Resumen

TLDRIn this educational video, the viewer is guided through the bones of the human skeleton with Mortimer, a skeletal model. The skeleton is divided into two main sections: the axial skeleton, which includes the skull, vertebrae, and ribs, and the appendicular skeleton, consisting of the arms, clavicle, scapula, and legs. Starting with the skull, the video covers bones like the frontal, parietal, temporal, and occipital bones, followed by the mandible and maxilla. Mortimer helps illustrate the body's core structure, including the sternum and ribs, explaining the difference between true, false, and floating ribs. Vertebrae are categorized into cervical, thoracic, and lumbar groups, ending with the sacrum and coccyx. The video transitions to the appendicular skeleton, discussing the clavicle, scapula, and limbs. The arms consist of the humerus, radius, ulna, carpals, metacarpals, and phalanges, while the legs include the femur, patella, tibia, fibula, and foot bones such as the calcaneus and tarsals. The lesson concludes with a review quiz and encourages interaction with the skeletal model, Mortimer. The tutorial provides a comprehensive understanding of human skeletal anatomy, focusing on structure, categorization, and connection between bones.

Cronología

  • 00:00:00 - 00:05:00

    The video begins with the presenters discussing their excitement about learning the bones of the skeletal system. They intend to cover the bones starting from the skull and working down through the axial skeleton, then moving to the appendicular skeleton. The skull is introduced, highlighting its developmental process from cartilage to bone, and the various bones it comprises such as the frontal, parietal, occipital, and temporal bones. The skull's role in housing and protecting the brain is emphasized, and its connection to the spinal cord is pointed out. Further discussion involves the mandible and maxilla, explaining their placement and function in relation to the skull.

  • 00:05:00 - 00:14:22

    The narrative progresses to the sternum and ribs, detailing the composition and categories of ribs as true, false, and floating. The speaker counts the ribs and describes the anatomy, explaining the connection via costal cartilage. The vertebrae of the spine are covered, categorized by cervical, thoracic, lumbar, sacral, and coccyx. The presenter relates these bones to the protection they offer, housing and safeguarding the brain, spinal cord, and vital organ structures. The segment continues to distinguish between the axial and appendicular skeletons, setting up for the explanation of limbs, starting with the arms, elucidating the clavicle, scapula, humerus, radius, and ulna, and detailing how the bones work for flexibility and motion. The bones of the hand, including carpals, metacarpals, and phalanges, are examined, focusing on their roles in hand movement and structure.

    for the wait a minute
  • 00:00:03
    you all seen mortimer hey mortimer dude
  • 00:00:06
    i'm here what's up
  • 00:00:06
    dude we can't do the bones of the
  • 00:00:08
    skeletal system without you get over
  • 00:00:09
    here
  • 00:00:10
    wait what did he say it's time to do the
  • 00:00:12
    bones of the skeleton video
  • 00:00:13
    i've been waiting for this my entire
  • 00:00:15
    life i'm so excited i could cry if only
  • 00:00:17
    i had tear ducts
  • 00:00:18
    i'm coming i'm coming here we go i'm so
  • 00:00:21
    excited
  • 00:00:26
    all right that's more like it like i
  • 00:00:28
    said we're gonna learn all the bones of
  • 00:00:29
    the skeleton in this video
  • 00:00:31
    mortimer's here and we're ready to get
  • 00:00:32
    started let's do it
  • 00:00:34
    all right we're going to start from the
  • 00:00:35
    top on the skull and work our way down
  • 00:00:37
    through what we call the axial skeleton
  • 00:00:39
    and then we'll move to the arms and the
  • 00:00:41
    legs which we call the appendicular
  • 00:00:42
    skeleton and at the end of the video
  • 00:00:44
    we'll review all the bones again with
  • 00:00:45
    mortimer
  • 00:00:46
    and you can take a quick self quiz to
  • 00:00:48
    see what bones you've learned and what
  • 00:00:49
    you still need to practice
  • 00:00:50
    let's start with the skull at the top
  • 00:00:51
    which is removable here sorry mortimer
  • 00:00:54
    whether tis noble in the minds of
  • 00:00:56
    yeah i don't know what that line is so
  • 00:00:58
    here's the skull of course and it houses
  • 00:00:59
    your brain
  • 00:01:00
    the main part of the skull here contains
  • 00:01:02
    several bones that get sutured together
  • 00:01:04
    whenever you're developing as a baby you
  • 00:01:06
    know how babies have a soft spot on
  • 00:01:07
    their head
  • 00:01:08
    that's because a lot of this is
  • 00:01:09
    cartilage and then it fills in with bone
  • 00:01:11
    over time as these bones grow together
  • 00:01:14
    and form your adult skull
  • 00:01:15
    the parts of the skull also match the
  • 00:01:17
    lobes of the cerebrum so if you know
  • 00:01:18
    those lobes
  • 00:01:19
    the names of these parts of the skull
  • 00:01:21
    will sound very familiar to you first
  • 00:01:22
    off we have the frontal bone
  • 00:01:24
    which is going to cover this frontal
  • 00:01:25
    part we have the parietal bones which
  • 00:01:27
    will be these bones right here
  • 00:01:29
    on the top of your head and we have the
  • 00:01:30
    occipital bone
  • 00:01:32
    around the back right here on either
  • 00:01:34
    side we have what's called the temporal
  • 00:01:35
    bone
  • 00:01:36
    like your temples so again those are the
  • 00:01:38
    frontal bone the parietal bones
  • 00:01:40
    the occipital bone and then the temporal
  • 00:01:42
    bones one of which you have on each side
  • 00:01:45
    like i said the skull houses your brain
  • 00:01:47
    and you can see
  • 00:01:48
    these kind of interesting shapes and
  • 00:01:50
    that's where the brain sits in there and
  • 00:01:51
    you see this big hole right here
  • 00:01:52
    which is where the brain connects to the
  • 00:01:54
    spinal cord did you know you had a big
  • 00:01:56
    spike in your head
  • 00:01:57
    in case you didn't know that's not
  • 00:01:59
    really there that's just for the model
  • 00:02:00
    by the way
  • 00:02:01
    if you do have a large metal spike in
  • 00:02:02
    your head go to the doctor right now
  • 00:02:04
    like seriously call 9-1-1 two more parts
  • 00:02:06
    of the skull this part right here that's
  • 00:02:08
    superior to your mouth is called the
  • 00:02:09
    maxilla
  • 00:02:10
    and down here we have the mandible go
  • 00:02:12
    ahead and take a moment and stretch your
  • 00:02:14
    mandible out there
  • 00:02:16
    if you notice the mandible is actually
  • 00:02:18
    not really attached to the rest of the
  • 00:02:20
    skull
  • 00:02:20
    except by the joint in the jaw right
  • 00:02:23
    there so it's able to move freely from
  • 00:02:25
    the rest of the skull
  • 00:02:29
    much better
  • 00:02:32
    the next bone i want to talk about is
  • 00:02:33
    the sternum the sternum runs from here
  • 00:02:36
    down to this tip at the bottom and you
  • 00:02:37
    can feel your own there'll be a little
  • 00:02:39
    notch in your neck right here
  • 00:02:41
    and that's going to be that indentation
  • 00:02:43
    between these two bones
  • 00:02:45
    and your sternum and if you go down from
  • 00:02:47
    there down sort of in the center you
  • 00:02:49
    should be at the bottom of your sternum
  • 00:02:50
    you can feel where it sort of like pokes
  • 00:02:52
    down a little bit
  • 00:02:53
    that's going to be the bottom of the
  • 00:02:54
    sternum right here now branching out of
  • 00:02:56
    your sternum are a bunch of pieces of
  • 00:02:58
    cartilage
  • 00:02:59
    you see those pieces of cartilage right
  • 00:03:01
    here we call those the costal cartilage
  • 00:03:04
    and they connect your sternum to your
  • 00:03:06
    ribs right here as far as your ribs go
  • 00:03:08
    you've got 12 pairs of ribs if i count
  • 00:03:11
    in the front though i won't count 12
  • 00:03:12
    i'll count 1 2
  • 00:03:13
    3 4 5 6 7 8 sort of
  • 00:03:16
    so we can't really count them from the
  • 00:03:18
    front so i'm going to spin mortimer
  • 00:03:19
    around in the back so you can see
  • 00:03:20
    all of those ribs we can count the 12
  • 00:03:22
    pairs a little bit better from the back
  • 00:03:24
    here we've got 1
  • 00:03:24
    2 3 4 5 6 7 8 9
  • 00:03:28
    10 11 12 ribs and there's three
  • 00:03:30
    categories that we use for the ribs
  • 00:03:32
    we've got true ribs false ribs and
  • 00:03:34
    floating ribs here's how you can tell
  • 00:03:35
    the difference the true ribs are going
  • 00:03:37
    to connect
  • 00:03:37
    from the vertebrae of the spine to the
  • 00:03:40
    sternum
  • 00:03:41
    and there's going to be one piece of
  • 00:03:43
    costal cartilage for each
  • 00:03:45
    of the true ribs so we have a true rib
  • 00:03:47
    here a true rib here
  • 00:03:48
    a true rib here here and here for a
  • 00:03:51
    total of one two three four
  • 00:03:52
    five pairs of true ribs the false ribs
  • 00:03:55
    are where the rib
  • 00:03:56
    connects to a piece of costal cartilage
  • 00:03:58
    that joins with other costal cartilage
  • 00:04:00
    here so we've got one two three four
  • 00:04:02
    five
  • 00:04:03
    false ribs and finally we have two pairs
  • 00:04:05
    of floating ribs
  • 00:04:06
    you can see the floating rims actually
  • 00:04:08
    don't connect in the front they start
  • 00:04:09
    with the vertebrae right here
  • 00:04:11
    and they just extend out and they sort
  • 00:04:12
    of just float there they don't connect
  • 00:04:14
    in the front
  • 00:04:15
    so one two pairs of floating ribs so 12
  • 00:04:18
    pairs of ribs total
  • 00:04:19
    we've got five true ribs five false ribs
  • 00:04:22
    and two floating ribs in the back there
  • 00:04:25
    now connecting the skull to the ribs of
  • 00:04:26
    course are the vertebrae
  • 00:04:28
    of your spine and we categorize the
  • 00:04:29
    different vertebrae depending on where
  • 00:04:31
    they are and what they attach to
  • 00:04:32
    and if you know the names of the spinal
  • 00:04:34
    nerves these terms will sound very
  • 00:04:35
    familiar to you so in the most superior
  • 00:04:37
    part we have eight
  • 00:04:38
    cervical vertebrae we have 12 thoracic
  • 00:04:41
    vertebrae and the thoracic vertebrae are
  • 00:04:42
    called thoracic vertebrae because they
  • 00:04:44
    connect to the ribs that's why we have
  • 00:04:45
    12 of those in that category
  • 00:04:47
    so 8 cervical vertebrae 12 thoracic
  • 00:04:50
    vertebrae
  • 00:04:51
    then we have 5 lumbar vertebrae down
  • 00:04:53
    here and then we have this bone called
  • 00:04:54
    the sacrum
  • 00:04:55
    which has multiple nerves that extend
  • 00:04:57
    out of it and finally the tailbone which
  • 00:04:59
    is called the coccyx so 8 cervical
  • 00:05:00
    vertebrae
  • 00:05:01
    12 thoracic vertebrae 5 lumbar vertebrae
  • 00:05:04
    and then the sacrum and the coccyx now
  • 00:05:06
    all the bones that we've talked about so
  • 00:05:08
    far
  • 00:05:08
    the skull the vertebrae and the ribs are
  • 00:05:12
    all about protection the skull of course
  • 00:05:14
    protects your brain the vertebrae
  • 00:05:15
    protect your spinal cord your spinal
  • 00:05:17
    cord runs down
  • 00:05:18
    through the middle of all those
  • 00:05:19
    vertebrae and the ribs of course protect
  • 00:05:21
    your heart and your lungs
  • 00:05:22
    also all the bones that we've learned so
  • 00:05:23
    far are part of the axial
  • 00:05:25
    skeleton the axial skeleton is
  • 00:05:27
    everything kind of down the middle we've
  • 00:05:29
    got the skull
  • 00:05:30
    the maxilla mandible the sternum the
  • 00:05:32
    ribs
  • 00:05:33
    the vertebrae and the sacrum and coccyx
  • 00:05:36
    that's all part of the axial skeleton
  • 00:05:38
    everything else that i draw on the
  • 00:05:39
    diagram all in blue is going to be part
  • 00:05:40
    of the appendicular skeleton
  • 00:05:42
    appendicular the same as appendage means
  • 00:05:44
    things that are sticking out and so your
  • 00:05:46
    arms and your legs sort of stick out
  • 00:05:47
    from the main part of your torso
  • 00:05:49
    which is why they get the name
  • 00:05:50
    appendicular we'll start with the
  • 00:05:52
    shoulder and the arms
  • 00:05:53
    these two bones right here are your
  • 00:05:54
    collar bones or clavicles
  • 00:05:56
    you can feel your clavicle if you feel
  • 00:05:58
    right there on your neck
  • 00:06:00
    and those will connect from the sternum
  • 00:06:02
    to your shoulder blades which is called
  • 00:06:03
    your scapula your scapulas are posterior
  • 00:06:06
    to your ribs or behind your ribs
  • 00:06:08
    and they sort of slide around if you can
  • 00:06:10
    feel your scapula
  • 00:06:11
    you can feel it sliding around if you
  • 00:06:12
    move your shoulders like this if you
  • 00:06:14
    move your shoulders like this
  • 00:06:17
    and your scapula and your clavicle which
  • 00:06:19
    combined or known as the
  • 00:06:20
    pectoral girdle are going to form a
  • 00:06:22
    joint with this bone the humerus
  • 00:06:24
    your humerus of course is also known as
  • 00:06:26
    your funny bone
  • 00:06:30
    so this is your shoulder joint clavicle
  • 00:06:32
    scapula and the humerus
  • 00:06:34
    if we follow the humerus from the
  • 00:06:35
    proximal end down to the distal end
  • 00:06:37
    it's going to connect at your elbow
  • 00:06:39
    joint to two bones called the radius
  • 00:06:41
    and the ulna of these two bones in the
  • 00:06:43
    forearm the way to tell which is which
  • 00:06:45
    is to find the one that's on your thumb
  • 00:06:47
    side on your thumb side is going to be
  • 00:06:49
    the radius and i think of it like this i
  • 00:06:51
    take my thumb and i move it in a circle
  • 00:06:52
    well circles have a radius the bone on
  • 00:06:54
    the pinky side is called the ulna which
  • 00:06:56
    is kind of a tiny little word like your
  • 00:06:58
    tiny little pinky a lot of cute little
  • 00:07:00
    ulna
  • 00:07:00
    the reason i like to use the thumb and
  • 00:07:02
    the pinky to remember which is which is
  • 00:07:03
    because these bones actually move
  • 00:07:05
    across each other whenever you turn your
  • 00:07:07
    wrist like this
  • 00:07:08
    watch as the radius goes back and forth
  • 00:07:10
    over the ulna as
  • 00:07:11
    mortimer moves his wrist which brings us
  • 00:07:13
    to the bones in the hand
  • 00:07:15
    the wrist bones right here are called
  • 00:07:16
    the carpals and you've got a bunch of
  • 00:07:18
    them
  • 00:07:18
    you can see lots of tiny little bones
  • 00:07:20
    there those are the carpals
  • 00:07:21
    you can find those there in your wrist
  • 00:07:23
    just distal to the wrist are the
  • 00:07:25
    metacarpals
  • 00:07:26
    and these are the bones of the hand so
  • 00:07:28
    your metacarpals are these bones right
  • 00:07:29
    across here
  • 00:07:31
    so carpals metacarpals here the bones in
  • 00:07:33
    your fingers are called phalanges
  • 00:07:35
    high five yeah we're tight like that
  • 00:07:39
    and one single phalanges bone is not a
  • 00:07:41
    phalange it's called a phalanx so one
  • 00:07:44
    phalanx
  • 00:07:45
    or a bunch of phalanges so those are the
  • 00:07:47
    bones of the arm we've got the clavicle
  • 00:07:49
    the scapular shoulder blade in the back
  • 00:07:51
    there we've got the humerus
  • 00:07:53
    here we have the radius on the thumb
  • 00:07:55
    side the ulna on the pinky side
  • 00:07:57
    we have the carpals the metacarpals and
  • 00:07:59
    the phalanges
  • 00:08:00
    all right let's move down to the bones
  • 00:08:02
    of the leg and we'll start with what we
  • 00:08:03
    call the pelvic girdle
  • 00:08:04
    the pelvic girdle is made of the pelvis
  • 00:08:07
    which we see
  • 00:08:08
    right here and that connects directly to
  • 00:08:10
    the sacrum
  • 00:08:11
    back in there now on mortimer you see
  • 00:08:13
    all of the white which is the bone but
  • 00:08:14
    you see this yellowish color here as
  • 00:08:16
    well and you see it between the two
  • 00:08:17
    halves of the pelvis
  • 00:08:18
    that yellowish color right there is
  • 00:08:20
    cartilage so there's actually a piece of
  • 00:08:22
    cartilage between the two halves of the
  • 00:08:24
    pelvis which we call the pubic
  • 00:08:26
    symphysis we see this in the spine as
  • 00:08:28
    well there's all of these
  • 00:08:29
    yellowish discs right there those are
  • 00:08:31
    called the intervertebral discs
  • 00:08:34
    or the cartilage discs between each of
  • 00:08:36
    the vertebrae and that just makes your
  • 00:08:37
    spine a little bit more flexible
  • 00:08:39
    and this makes your pelvis a little bit
  • 00:08:40
    more flexible now the bones of the leg
  • 00:08:42
    will start with this the femur
  • 00:08:44
    which is the longest bone of the body
  • 00:08:46
    the proximal end of the femur connects
  • 00:08:48
    to the pelvis
  • 00:08:49
    and the distal end of the femur this
  • 00:08:51
    little bone called the patella or your
  • 00:08:52
    kneecap and the patella
  • 00:08:54
    can actually slide from here down over
  • 00:08:56
    your knee as you bend it mortimer you're
  • 00:08:58
    so flexible
  • 00:08:59
    look at that range of motion we have two
  • 00:09:00
    bones in the lower leg
  • 00:09:02
    here we have the tibia which is going to
  • 00:09:04
    be the bigger of the two bones
  • 00:09:05
    that's also your shin bone so if you
  • 00:09:07
    ever bang your shin on something
  • 00:09:09
    you're hitting your tibia right here and
  • 00:09:10
    there's not a lot of cushion between
  • 00:09:11
    your tibia
  • 00:09:12
    and the skin over your shin it's not
  • 00:09:14
    like the back of your leg where you got
  • 00:09:16
    your big calf muscle there for cushion
  • 00:09:17
    that's why your shin is so vulnerable to
  • 00:09:19
    painful collisions so you can feel your
  • 00:09:21
    tibia your fibula though which is sort
  • 00:09:23
    of surrounded by muscles on all sides
  • 00:09:25
    you can't really feel that one as easily
  • 00:09:27
    but this is the fibula right here so
  • 00:09:29
    tibia is the big bone fibula is the
  • 00:09:32
    smaller bone
  • 00:09:33
    whoa cool ankle bracelet now in the foot
  • 00:09:35
    itself we have your heel bone called the
  • 00:09:37
    calcaneus
  • 00:09:38
    wave with your foot the rest of the
  • 00:09:39
    bones of the foot kind of mirror the
  • 00:09:40
    bones of the hand
  • 00:09:41
    instead of the carpals we have the
  • 00:09:43
    tarsal bones so the tarsal bones are all
  • 00:09:45
    here
  • 00:09:45
    and then down here we have the calcaneus
  • 00:09:47
    and if we have tarsals then we have
  • 00:09:49
    metatarsals calcaneus tarsals
  • 00:09:52
    metatarsals and finally the bones of
  • 00:09:54
    your toes are also called phalanges easy
  • 00:09:56
    enough to remember so go ahead and take
  • 00:09:57
    a moment
  • 00:09:58
    wiggle all of your phalanges your
  • 00:09:59
    fingers and your toes
  • 00:10:01
    phalanges all right let's go and review
  • 00:10:02
    all the bones of the leg again we have
  • 00:10:04
    the pelvis here and the pubic symphysis
  • 00:10:06
    in between the two halves of the pelvis
  • 00:10:07
    we've got the femur we've got the
  • 00:10:09
    patella our kneecap
  • 00:10:10
    we've got the tibia that's the bigger
  • 00:10:12
    bone the shin bone
  • 00:10:14
    we've got the fibula you can also
  • 00:10:15
    remember that the fibula is always on
  • 00:10:17
    the side
  • 00:10:18
    i kind of remember it like it's got the
  • 00:10:19
    word fib in it like it's lying about who
  • 00:10:21
    it is it's like
  • 00:10:22
    yeah i contribute a lot to the stability
  • 00:10:24
    of the leg when really the tibia is
  • 00:10:25
    doing all the work the fibula is sort of
  • 00:10:26
    lying about its usefulness
  • 00:10:28
    that's probably not completely true it
  • 00:10:29
    probably is really important but that's
  • 00:10:31
    how i remember tibia
  • 00:10:32
    versus fibula the fibula it's lying it's
  • 00:10:33
    not doing that much it's a smaller one
  • 00:10:35
    and then we have the calcaneus or the
  • 00:10:36
    heel bone
  • 00:10:37
    we've got the tarsals the metatarsals
  • 00:10:40
    and the phalanges all right now mortimer
  • 00:10:42
    is going to provide us with the bones of
  • 00:10:44
    the skeleton tour let's go
  • 00:10:46
    here we have the skull of course we've
  • 00:10:49
    got the frontal bone right there
  • 00:10:51
    we've got the parietal bones on the top
  • 00:10:54
    there
  • 00:10:54
    we've got the occipital bone and of
  • 00:10:56
    course the temporal bone on the side
  • 00:10:59
    we've got the maxilla right there and
  • 00:11:01
    the mandible
  • 00:11:02
    down there and here's a view from the
  • 00:11:04
    bottom that's kind of cool looking
  • 00:11:05
    that big hole is where the spinal cord
  • 00:11:07
    enters up into the brain
  • 00:11:10
    all right you just chill right there for
  • 00:11:12
    a second i'll be right back okay boss
  • 00:11:13
    here we've got the sternum with the
  • 00:11:14
    notch right there
  • 00:11:16
    and then this protrusion sticking out
  • 00:11:17
    right there we've got the costal
  • 00:11:19
    cartilage
  • 00:11:20
    which connects from the sternum to the
  • 00:11:22
    ribs and of course we have five true
  • 00:11:24
    ribs
  • 00:11:24
    five false ribs and in the back here we
  • 00:11:26
    can see the two floating ribs they don't
  • 00:11:28
    connect to anything
  • 00:11:30
    anymore around the back we've got
  • 00:11:33
    cervical vertebrae up here eight of
  • 00:11:35
    those
  • 00:11:36
    twelve thoracic vertebrae that are all
  • 00:11:37
    connected to one of the ribs
  • 00:11:39
    the lumbar vertebrae we've got the
  • 00:11:42
    sacrum
  • 00:11:42
    and then the coccyx or the tailbone
  • 00:11:45
    back to the front we've got the clavicle
  • 00:11:48
    which connects from the sternum
  • 00:11:49
    over to the scapula the scapula is kind
  • 00:11:51
    of a strain shaped bone it's kind of a v
  • 00:11:53
    shape right here plus it's got this
  • 00:11:54
    protrusion sticking out right there
  • 00:11:56
    that's your shoulder blade it connects
  • 00:11:57
    to the humerus
  • 00:11:58
    the humerus runs down here where it
  • 00:12:00
    connects to the radius
  • 00:12:01
    and the ulna here's the radius on the
  • 00:12:04
    thumb side
  • 00:12:05
    here's the ulna on the peaky side and of
  • 00:12:07
    course we have got the carpals
  • 00:12:09
    the metacarpals of the hand and then the
  • 00:12:11
    phalanges
  • 00:12:15
    up here we've got the pelvis and the
  • 00:12:17
    pubic symphysis which is the cartilage
  • 00:12:19
    between the two halves of the pelvis
  • 00:12:21
    we've got the femur which runs all the
  • 00:12:23
    way down here
  • 00:12:24
    oop apparently more stand is broken
  • 00:12:26
    we've got the patella or the kneecap
  • 00:12:28
    we have the tibia that's the big bone
  • 00:12:30
    there we've got the fibula the small
  • 00:12:32
    bone
  • 00:12:32
    down over here we've got the calcaneus
  • 00:12:35
    that's the heel bone back there
  • 00:12:37
    we've got the tarsals the metatarsals
  • 00:12:40
    and then finally the phalanges there at
  • 00:12:42
    the bottom all right thanks for the tour
  • 00:12:44
    mortem
  • 00:12:45
    oops thanks for the tour mortimer uh no
  • 00:12:47
    problem can you put my head back on now
  • 00:12:49
    uh no problem
  • 00:12:50
    you got it all right here's a blank
  • 00:12:52
    version of our diagram
  • 00:12:53
    take a moment pause the video and see if
  • 00:12:54
    you can identify all of the bones in the
  • 00:12:56
    diagram
  • 00:12:58
    all right here we have the skull and of
  • 00:12:59
    course the skull contains the frontal
  • 00:13:01
    bone parietal bone occipital bone
  • 00:13:03
    temporal bone maxilla and mandible we've
  • 00:13:06
    got the vertebrae which will include 8
  • 00:13:08
    cervical
  • 00:13:08
    12 thoracic 5 lumbar and then the sacrum
  • 00:13:12
    and the coccyx
  • 00:13:13
    we have the sternum and we have the
  • 00:13:14
    costal cartilage branching out of the
  • 00:13:16
    sternum which connect to the ribs
  • 00:13:18
    we've got five true ribs five false ribs
  • 00:13:21
    and two floating ribs in the back we
  • 00:13:23
    have the pectoral girdle which includes
  • 00:13:24
    the clavicle
  • 00:13:25
    the scapula or shoulder blade the
  • 00:13:28
    humerus the radius on the thumb side the
  • 00:13:30
    ulna on the pinky side
  • 00:13:32
    the carpals metacarpals and phalanges
  • 00:13:35
    and then all of the leg bones we have
  • 00:13:36
    the pelvis
  • 00:13:37
    the pubic symphysis is a piece of
  • 00:13:38
    cartilage between the halves of the
  • 00:13:40
    pelvis the femur
  • 00:13:41
    the kneecap called the patella we've got
  • 00:13:44
    the tibia
  • 00:13:45
    fibula calcaneus tarsals
  • 00:13:48
    metatarsals and the phalanges of the
  • 00:13:50
    feet and of course all these bones
  • 00:13:52
    down the center are called the axial
  • 00:13:54
    skeleton and all the bones of the arms
  • 00:13:56
    and the legs are called the appendicular
  • 00:13:58
    skeleton
  • 00:13:59
    mortimer should we start a band what
  • 00:14:00
    would i do well i could see
  • 00:14:03
    no i can't sing really skull is
  • 00:14:05
    connected to the
  • 00:14:06
    cervical vertebrae cervical vertebra
  • 00:14:08
    connected to the thoracic vertebrae
  • 00:14:10
    the thoracic vertebra connected to the
  • 00:14:11
    ribs the ribs are connected to the
  • 00:14:14
    sternum the vertebrae also connected to
  • 00:14:16
    the
  • 00:14:17
    you know it's hard to do an anatomically
  • 00:14:19
    correct version of that song
