the gi tract always has a

lumen (open space in center)

Front 4

four layers seen throughout the gi tract from lumen to serous memb

Front 5

submucosa

Back 5

areolar connective tissue

Front 6

muscularis

Back 6

also called muscularis externa to distinguish it from the thinner weaker muscle layer of the mucosa above

Front 7

serosa in abdomen

Back 7

serosa forms part of the peritoneal cavity

Front 8

mucosa is the layer that

Back 8

lines the lumen

Front 9

three sublayers of mucosa

Back 9

epithelium, lamina propria, muscularis mucosae

Front 10

epithelium

Back 10

stratified squamous in the mouth and simple columnar in the stomach and intestines

Front 11

a layer of areolar connective tissue with blood and lymphatic vessels to pick up material absorbed by the epithelium

Back 11

lamina propria

Front 12

a thin muscle layer that makes the inside of the GI tract all crinkly and folded

Back 12

muscularis mucosae

Front 13

what comprises areolar connective tissue. in it, we find blood and lymphatic vessels and the submucosal plexus of the enteric nervous system.

Back 13

submucosa

Front 14

striated (voluntary) muscle in the mouth and pharynx controls swallowing. Smooth muscle, usually in two layers, lines the rest of the GI tract and keeps materials moving through peristalisis

Back 14

muscularis

Front 15

the what is made up of areolar connective tissue covered by a simple squamous epithelium.

Back 15

serosa

Front 16

in the abdominal cavity, serosa is alled the

Back 16

visceral peritoneum becuase it forms guts side of peritoneal cavity

Front 17

buccal

Back 17

towards cheek

Front 18

lingual

Back 18

towards toungue

Front 19

occlusal

Back 19

for teeth, towards the surface where they meet other teeth

Front 20

mesial

Back 20

toward midline

Front 21

distal

Back 21

farther away from the midline

Front 22

incisors

Back 22

sharp cutting theeth

Front 23

cuspids

Back 23

canine teeth

Front 24

bicuspids

Back 24

premolars

Front 25

molars

Back 25

grindstone

Front 26

maxilla

Back 26

upper jaw

Front 27

mandible

Back 27

lower jaw

Front 28

numbering teeth

Back 28

starts from patients right distal maxillary molar

Front 29

children have how many teeth

Back 29

20 that fall out

Front 30

the part of the tooth above the gumline and visible is the

Back 30

crown

Front 31

the part just below the gumline

Back 31

neck

Front 32

the part of the tooth that attaches the tooth to the periodontal ligaments and then to the jawbone

Back 32

root

Front 33

the outher part of the tooth forming the occlusal surface and all four sides of the tooth

Back 33

enamel

Front 34

enamel made up of

Back 34

minerals calcium phosphate and calcium carbonate.

Front 35

enamel is harder than bone because

Back 35

it is almost all mineral with little organic matrix

Front 36

deep in the enamel is

Back 36

dentin

Front 37

what forms the bulk of the tooth

Back 37

dentin

Front 38

dentin contains

Back 38

dentinal tubules which allow fluid to move

Front 39

when dentin is exposed

Back 39

fluid can move (as if dentinal tubules are tiny drinking straws) and the nerves of the root send strong pain signal to brain

Front 40

the dentin of the root is covered by

Back 40

cementum

Front 41

cementum is connected to bone by a series of

Back 41

periodontal ligaments, a dense fibrous connective tissue

Front 42

what has proprioception and are resistant to anesthesia, which is why we can feel pressure during dental work

Back 42

periodontal ligaments

Front 43

the pain fibers and blood vessels of teeht are enxlosed in

Back 43

pulp cavity

Front 44

pulp cavity

Back 44

chamber formed by dentin with one to three outlets

Front 45

pain signals carried by apical foramina are carried on the

Back 45

trigeminal nerve

Front 46

tongue is made up of

Back 46

skeletal muscle covered by an epithelium

Front 47

filiform papillae

Back 47

look like threads cover mos of thongue surface. nontaste structure that gives rough texture

Front 48

what are clustered in taste buds

Back 48

gustatory receptor

Front 49

taste buds are found

Back 49

on the toungue in htree groupings

Front 50

three taste buds found on the tongue

Back 50

fungiform papillae, foliate papillae, vallate papillae

Front 51

foliate papillae are found on what part of the tongue

Back 51

laeral surface of the posterior tongue

Front 52

vallate papillae form a

Back 52

v shape row along the posterior tongue

Front 53

lingual glands

Back 53

secrete mucus plus an enzyme, lingual lipase, wich helps break down fatty foods in the mouth

Back 57

submandibular glands/ducts

Front 58

mucous acini

Back 58

make mucus

Front 59

serous acini

Back 59

make water and enzymes

Front 60
