questions for final exam functions of
00:00:13
the justice system main functions
00:00:16
breaking down food for absorption into
00:00:20
the body for energy production for
00:00:26
synthesis of substances necessary for
00:00:30
the body
00:00:32
this process is include intestine of the
00:00:36
food it's shaving moist in and swallowin
00:00:40
we take place in the oral cavity the
00:00:45
gradation of food by digestive enzymes
00:00:49
absorption of the products and release
00:00:53
of undigested remnants of food through
00:00:58
anus the juices system consists of
00:01:04
elementary canal and big digestive
00:01:10
glands located outside elementary kernel
00:01:18
includes oral cavity pharynx is a Fergus
00:01:26
stomach and intestine
00:01:32
all of them are tubular organs big
00:01:37
digestive glands includes big thorough
00:01:42
glands liver and pancreas there / in

00:02:45
the Lamont era Colonel wall as in all
00:02:51
other tubular organs consists of three
00:02:56
membranes the inner membrane called
00:02:59
Makos membrane middle called muscular
00:03:04
membrane and outer called Searles
00:03:09
membrane or augmentation
00:03:13
every membrane consists of layers this
00:03:22
figure demonstrate is a plane of a

part three membrane Mako's membrane
00:04:07
where muscle membrane and advanced issue
00:04:15
or surahs' membrane
00:04:21
Mako's memory consists of four layers
00:04:24
epithelial layer in an Turin and
00:04:30
postural parts it represented by
00:04:34
stratified squamous mostly
00:04:38
non-keratinized epithelium in the middle
00:04:44
part it simple columnar at the theorem
00:04:54
in the stomach is simple columnar
00:05:00
secretory because it's secreted mucus in
00:05:07
intestine it's simple columnar
00:05:13
absorptive because it's contained brush
00:05:18
border micro village for but absorption
00:05:23
of products of digestion of food
00:05:34
second layer lamina propria it's a loose
00:05:39
connective tissue
00:05:45

00:09:08
epithelium for exception of this
00:09:14
certainly
00:09:17
there are several organs inside oral

Hooten have sparked represented by skin
00:11:45
intermediate part covered by stratified
00:11:51
squamous non-keratinized epithelium
00:11:54
quite thin so it's lucid it's a reason
00:12:04
where the color is red bright pink
00:12:10
because the red blood in numerous blood
00:12:18
vessel whistles visible through the
00:12:21
episode on the inner mucosal part
00:12:27
covered by maquas membrane and it's
00:12:32
lamina propria and stratified squamous
00:12:39
non-keratinized epithelium but it's much
00:12:43
see this is a tan this longitudinal
00:12:47

eight and
00:13:32
circumvallate papillae they surrounded
00:13:36
these are a latch but flat they
00:13:41
surrounded by volume so it's
00:13:45
circumvallate papillae and around also
00:13:51
the foldings of mucous membrane popular
00:13:56
are really the connective tissue core
00:14:03
covered by epithelium in epithelium in
00:14:10
these three types of papilla of the

oral cavity there are three types of
00:17:12
secretary potions Cyril's consist of oxy
00:17:18
fill excels is around new clay which
00:17:24
produce watery
00:17:27
secret and proteins enzymes like amylase
00:17:34
to digest carbohydrates
00:17:37
Mako's secretary post produce mucus the
00:17:44
complex glycoproteins molecules with

00:19:02
oxy philic they called Searles semi
00:19:07
loons
00:19:09
parotid gland contain only shiro
00:19:15
secretary potions
00:19:17
submandibular glands contain both
00:19:26
Searles and mixed secretary portions and
00:19:32
sublingual gland contain fewer moko
00:19:41
secretary portion mixed and few zeros
00:19:49
the DAX system consists of the smallest
00:19:55
intercalated ducts linen by cuboidal or
00:20:04
squamous epithelium they damn it a much
00:20:10
smaller than socotra portions then
00:20:15
straight it that's because in basal part
00:20:19
they have stration consists of folds of

00:20:35
irregular in these false
00:20:41
it demonstrated the ability for
00:20:44
transport of ions between blood and

saliva from several Global's
00:21:23
and finally the main duct which release
00:21:28
secret from all Mobile's into the oral
00:21:33
cavity in addition of there are special
00:21:37
cells his long processes which covered
00:21:46
the circulatory portions
00:21:47
it's my epithelial cells which can
00:21:53
contract and push they secret into the
00:21:58
ducts this is a micro photograph of
00:22:03
parotid parotid gland contain only cyril
00:22:10
secretary potion and here the straight
00:22:15
duct visible and this picture
00:22:20
demonstrates the sublingual glands which
00:22:24
contained mostly Makos secretary
00:22:29
portions and mixed is Searles similans
00:22:36

00:23:18
about one and half little salut up a day
00:23:22
in the current function big seller of
00:23:27
let's produce insulin parity in grozny
00:23:32
factors factor or growth of epithelium
00:23:40
excretory they can express it excrete
00:23:45
release some waste products like uric
00:23:49
acid Croton in iron a organ protective
00:23:55
they produce listen enzymes which digest
00:24:00
the bacterial wall lipid epithelial
00:24:05
throat ring of pirogov aldair its
00:24:11
include five types of tonsils this
00:24:18
polythene Danzo he is foreign girl tone
00:24:23
so for example they're located between
00:24:27
oral cavity and pharynx so adjust the
00:24:34
entrance into the elementary kernel and
00:24:40
Airways the structure of all tonsils
00:24:45
quite similar for example here is a
00:24:50
picture of collagen Danzo
00:24:55
here the mucous membrane make tubalove
00:25:00
folds called groups in lamina propria
00:25:07
and epithelium innumerous an emphatic
00:25:12
follicles located this geminal light
00:25:19
germinal centers inside there be zones
00:25:25
they located they composed by B
00:25:31
lymphocytes and between T zones contains
00:25:37
some T lymphocytes so here's a antigen
00:25:44
dependent proliferation and
00:25:46
differentiation of teen B lymphocytes
00:25:51
take place so lymphocytes here contact
00:25:58
these antigens cloning the phrase and
00:26:05
converged to effector cells me and cover
00:26:09
an epithelium here infiltrated by
00:26:12
lymphocytes so it looks much darker as
00:26:18
compared to normal at the theorem there
00:26:24
is also the cops'll around connective
00:26:29
tissue layer so it looks like parenchyma
00:26:33
organ this
00:26:39
is an hour and out there are 32 teeth
00:26:45
and quarter will be eight two incisors
00:26:55
one cannon two premolars and three
00:27:02
molars so eight four four thirty two
00:27:09
parts of those crowns neck and root and
00:27:15
here only crowns visible if you remove
00:27:23
the soft tissues you can see the next
00:27:28
day under gums if you remove some bone
00:27:41
jeweler bones we can see the roots most
00:27:48
of this is one route but molars have two
00:27:56
or three roots which located in Alva
00:28:01
halls of the maxilla or mandibular so
00:28:07
parts of tooth crown neck intrude
00:28:16
from histological point of view tooth
00:28:22
consists of dense and soft tissues dense
00:28:29
enamel dentin teen and cementum cement
00:28:40
governs root and soft tissue represented
00:28:48
by pulp inside inside pulp cavity in
00:28:57
kernel and periodontal or this ligament
00:29:04
between a root of tools and alveolar
00:29:15
bone so to structure dense tissues
00:29:23
animal the hardest issue of the body
00:29:30
contained 96% of minerals consists of
00:29:37
s-shape prisms
00:29:46
connected by matrix arrow prism consists
00:29:53
of parallel collagen fibrils it is
00:30:02
crystals of hydroxyapatite between no
00:30:08
cells available here did dentine like
00:30:18
born contactable 70 percents of minerals
00:30:22
also mainly as crystals of
00:30:28
hydroxyapatite there is no cells in
00:30:33
Denton only processes of cells allocated
00:30:40
in Denton canaliculi in dentin tubules
00:30:46
going in parallel up to animo the bodies
00:30:54
of 19 hablas located in pulp on the
00:31:01
border near the border of dentin they
00:31:10
secrete some dentin components in adults
00:31:18
also cementum covers the root of tooth
00:31:26
cement contain 70% of minerals consist
00:31:34
of cellular cementum in the deeper part
00:31:40
of root it contained the cells cement
00:31:45
asides so the structure of Salalah
00:31:49
cementum like the ridiculous ebro's born
00:31:53
but there was still says and Ansel over
00:32:03
cementum in Abbas contained no cells
00:32:09
only into cellular matrix soft tissues
00:32:14
consists of two spalled
00:32:20
and periodontal dispell consists of
00:32:28
three layers peripheral contained in
00:32:33
tanam blasts and poured in teen
00:32:38
intermediate contained stem cells
00:32:43
precursors of lanthanum blasts and
00:32:47
central but loose connective tissue is
00:32:51
blood vessels and nerves period aunt or
00:32:58
two segments consist of dense irregular
00:33:02
connective tissue and collagen fibers
00:33:06
going in parallel from cementum till
00:33:15
alveolar bone and they connected tooth
00:33:20
and bone and fix the tools in our all of
00:33:32
bones max-level mandibular jeweler bone
00:33:37
and gums cover of the neck of tooth they
00:33:50
covered by stratified non-keratinized at
00:33:55
the theorem squamous non-keratinized
00:33:58
epithelium which connected with animal
00:34:03
tooth development animal organ the tooth
00:34:12
rudiments appeared on the second third
00:34:17
months of embryogenesis
00:34:24
from the passivity zen dental lamina
00:34:30
developed then tooth baths which grow
00:34:39
win became big and bigger and surrounded
00:34:46
missing home push this body and
00:34:52
mesenchyme around produces tooth animal
00:34:57
suck so this animal organ consists of
00:35:04
three layers of cells in a outer and
00:35:10
intermediate and it's contained the neck
00:35:17
this is a precursor of for every tooth
00:35:26
and from these precursors bull tissues
00:35:37
of tooth developed there are three main
00:35:44
types of cells ameloblasts or animal
00:35:50
oblasts which appeared from the inner
00:35:56
life animal organs they will produce
00:36:03
animal from the amazin home of dental
00:36:10
papilla appeared in tina Blas which
00:36:16
produce dentine from mesenchyme the
00:36:24
cementum appeared pulp
00:36:29
and Peter don't
00:36:33
and this microphotography must raise the
00:36:41
tooth board animal organ and development
00:36:48
of TCO animal hablas which produce
00:36:52
animal and dentin hablas which produced
00:36:55
dentin and as a result the rudiments of
00:37:03
milk the permanent teeth appeared and
00:37:14
between six months two years after
00:37:18
delivery
00:37:24
of the Milky 20 yen milky teeth appeared
00:37:31
later between six and thirty years
00:37:35
they're destroyed placed for permanent
00:37:41
permanent teeth certainly only twenty
00:37:46
milk cheese replaced by permanent molars
00:37:52
twelve molars
00:37:55
you know permanent teeth the teeth
00:38:03
Boris consists of dense very strong
00:38:08
dense tissues but a very quality quite
00:38:13
sensitive to destruction
00:38:16
for example animal can be destroyed by
00:38:21
acids and the defects if they appeared
00:38:28
cannot normally and naturally replaced
00:38:32
by new animal because no cells here in
00:38:40
Denton the defects may be very slow
00:38:47
replaced by second rent in it produced
00:38:52
by dentin oblasts and the same situation
00:38:57
for cementum
00:39:07
you
