    Cranial nerves arise from the brain, including the brain stem, with 12 pairs best seen from an inferior view. Learning their functions is aided by memorizing a diagram of a head and shoulders. Each nerve has specific roles: Olfactory nerve (smell), Optic nerve (vision), Oculomotor nerve (eye movements, autonomic functions like eyelid elevation), Trochlea nerve (eye movement down and out), Trigeminal nerve (facial sensation, motor functions like chewing), Abducens nerve (eye abduction), Facial nerve (facial expression, taste), Vestibular cochlear nerve (hearing and balance), Glossopharyngeal nerve (taste, swallowing), Vagus nerve (pharynx/larynx sensation, autonomic functions), Accessory nerve (shoulder movement), and Hypoglossal nerve (tongue movement).

    hi-yah welcome to biomed sessions with
  • 00:00:02
    me Ruth today we're going to be learning
  • 00:00:04
    the functions of the cranial nerves
  • 00:00:07
    cranial nerves are nerves arising from
  • 00:00:09
    the brain including brain stem they are
  • 00:00:11
    best seen from an inferior view
  • 00:00:13
    I either on the side of the brain and
  • 00:00:15
    there are 12 pairs of them in total
  • 00:00:17
    numbered according to where each emerges
  • 00:00:19
    a good way of learning cranial nerve
  • 00:00:21
    functions is by copying out and
  • 00:00:24
    memorizing this picture which is
  • 00:00:26
    basically just a head with shoulders
  • 00:00:27
    composed of the numbers of all 1 2 3 4 5
  • 00:00:32
    6 7 8 9 10 11 12 pairs of cranial nerves
  • 00:00:38
    learn this and you'll have a pretty good
  • 00:00:40
    idea of what each pair does we'll go for
  • 00:00:42
    it together cranial nerve one is the
  • 00:00:45
    olfactory nerve it is sensory therefore
  • 00:00:47
    relays information back to the brain in
  • 00:00:49
    this case this will be in relation to
  • 00:00:51
    olfaction which is basically just your
  • 00:00:54
    sense of smell handy because the number
  • 00:00:56
    one is the nose in the diagram cranial
  • 00:00:59
    nerve two also sensory is the optic
  • 00:01:01
    nerve and is involved in vision
  • 00:01:03
    number three is the oculomotor nerve
  • 00:01:06
    it's is mainly motor
  • 00:01:08
    hence relays information from the brain
  • 00:01:10
    to effectors such as muscle alongside
  • 00:01:12
    cranial nerves four and six the
  • 00:01:14
    oculomotor nerve is involved in eye
  • 00:01:16
    movements it is in fact related to so
  • 00:01:19
    many eye movements that it would be best
  • 00:01:20
    to learn which eye movements is not
  • 00:01:22
    involved in if isolated it cannot help
  • 00:01:24
    move the eye down and out
  • 00:01:26
    this is the job of cranial nerve 4 and
  • 00:01:28
    it does not help abduct the eye this is
  • 00:01:31
    the job of cranial nerve 6 the
  • 00:01:33
    oculomotor nerve also has autonomic
  • 00:01:35
    functions ie those that are involuntary
  • 00:01:38
    / unconscious these include eyelid
  • 00:01:40
    elevation pupil constriction and changes
  • 00:01:43
    in the shape of the lens in order to
  • 00:01:45
    focus on objects this is known as lens
  • 00:01:47
    accomodation cranial nerve 4 is the
  • 00:01:50
    trochlea nerve as mentioned previously
  • 00:01:52
    it is involved in moving the eye down
  • 00:01:54
    and out this actually occurs for a
  • 00:01:56
    combination of depression abduction and
  • 00:01:59
    inward rotation of the eye cranial nerve
  • 00:02:01
    5 the trigeminal nerve is mixed carrying
  • 00:02:04
    both sensory and motor fibres tri means
  • 00:02:07
    three which hints at the fact that this
  • 00:02:09
    nerve has three branches which together
  • 00:02:11
    aid in facial and tea
  • 00:02:13
    sensation in addition to sensation from
  • 00:02:15
    the front and middle thirds of the
  • 00:02:17
    tongue or more officially the anterior
  • 00:02:19
    two-thirds also it has motor fibers
  • 00:02:22
    which are involved in mastication ie
  • 00:02:24
    biting and chewing as we know the
  • 00:02:27
    abducens nerve cranial nerve six the
  • 00:02:29
    lustres of free nerves involved in eye
  • 00:02:30
    movement abducts the eye abducens
  • 00:02:33
    abduction cranial nerve seven is the
  • 00:02:36
    facial nerve
  • 00:02:36
    it has motor fibres for facial
  • 00:02:38
    expression and sensory fibers which are
  • 00:02:40
    involved in taste from the anterior
  • 00:02:42
    two-thirds of the tongue not to be
  • 00:02:44
    confused with the trigeminal nerve which
  • 00:02:46
    aids in general sensation to this same
  • 00:02:48
    region a good way of remembering the
  • 00:02:49
    facial nervous function is to imagine
  • 00:02:51
    your facial expression as you taste your
  • 00:02:53
    favorite piece of food additionally the
  • 00:02:56
    facial nerve is involved in saliva and
  • 00:02:58
    tear secretion the vestibular cochlear
  • 00:03:00
    nerve cranial nerve 8 is a sensory nerve
  • 00:03:03
    which gets its name from the structures
  • 00:03:05
    in the inner ear which it innervates the
  • 00:03:06
    cochlea which is involved in hearing and
  • 00:03:09
    the vestibule which is involved in
  • 00:03:11
    balance
  • 00:03:11
    hence the vestibular cochlear nerve aids
  • 00:03:13
    in these functions the glossopharyngeal
  • 00:03:15
    nerve cranial nerve nine also has an
  • 00:03:18
    interesting name Glosser
  • 00:03:20
    means tongue and pharynx is the back
  • 00:03:22
    part of the throat hence it's no
  • 00:03:24
    surprise that it carries sensory fibers
  • 00:03:26
    for taste and sensation from the
  • 00:03:28
    posterior third are you the back part of
  • 00:03:30
    the tongue and has motor fibers that aid
  • 00:03:32
    in swallowing it is also involved in
  • 00:03:34
    saliva secretion cranial nerve 10 is the
  • 00:03:37
    vagus nerve now although I drew it
  • 00:03:39
    really small on this diagram the vagus
  • 00:03:41
    nerve is actually a huge nerve which is
  • 00:03:43
    mixed and extends further than all of
  • 00:03:44
    the cranial nerve which is why it is
  • 00:03:46
    referred to as the wandering nerve
  • 00:03:47
    indeed it wanders about and supplies a
  • 00:03:49
    wide range of structures on the sensory
  • 00:03:52
    side it carries sensations from the
  • 00:03:53
    pharynx larynx 4ax abdomen etc it is
  • 00:03:57
    also involved in taste using a flap of
  • 00:03:59
    tissue at the back of the throat known
  • 00:04:00
    as the epiglottis it has motor fibres
  • 00:04:02
    which aid in swallowing and speech and
  • 00:04:04
    autonomic functions such as decreasing
  • 00:04:06
    heart rate gastrointestinal tract
  • 00:04:08
    contractions to aid in moving along food
  • 00:04:10
    and sweating you'll be relieved to know
  • 00:04:13
    that our next nerve cranial nerve 11 is
  • 00:04:15
    much simpler in terms of function the
  • 00:04:17
    accessory nerve carries motor fibers
  • 00:04:19
    which help you shrug your shoulders and
  • 00:04:20
    turn / tilt your head and finally
  • 00:04:23
    cranial nerve 12 is a hypoglossal nerve
  • 00:04:25
    which is purely motor
  • 00:04:27
    if you remember glossa means tongue and
  • 00:04:29
    hypo actually means under hence this is
  • 00:04:31
    a nerve that is part of the on the
  • 00:04:33
    surface of the tongue and aids in tongue
  • 00:04:35
    movements okay that's how 12 pairs of
  • 00:04:37
    cranial nerves done if you found this
  • 00:04:39
    tutorial helpful give it a thumbs up and
  • 00:04:41
