Flashcards in Mouth and tongue Deck (61):
1

What is the thin epidermis that covers the lips?

Transitional zone

2

The border between the lips and the orbicularis oris muscle

Vermilion border

3

Another name for the cleft of the lip

Philtrum

4

Extension of the inner alveolar mucosa at midline from base of each lip to adjacent gum

Frenulum

5

What is between the buccinator and the superficial skin?

Buccal fat pad

6

Space between the teeth and gums internally/lips and cheeks externally

Oral vestibule

7

Space internal to the teeth, and mandibular/maxillary alveoli

Oral cavity proper

8

Muscular floor of the mouth is formed by what?

Mylohyoid and geniohyoid

9

Muscle that runs from the mental spines to the hyoid

Geniohyoid

10

Mandibular attachment point for the mylohyoid

Mylohyoid line

11

Fold of mucosa extending from the midline of the floor of the mouth, across inferior surface of the tongue towards the tip of the tongue

Frenulum of the tongue

12

Gland just deep to the mucosa of the floor of the mouth, forming a ridge

Sublingual gland (forms sublingual ridge)

13

Location of superficial part of the submandibular gland

Deep to platysma in submandibular triangle (more inferior than deep part)

14

Location of deep part of the submandibular gland

Superior to the mylohyoid (closer to submandibular gland)

15

Exit point for the saliva of the submandibular gland

Sublingual caruncle

16

4 types of teeth

incisor, canine, premolar, molar

17

3 free surfaces of a tooth

Superficial, deep, occlusive

18

3 parts of a tooth

Crown, neck, root

19

What is a tooth primarily composed of?

Dentin

20

Covers the dentin of the crown

Enamel

21

Covers the dentin of the root

Cement

22

Where does enamel transition into cement?

Neck of the tooth

23

Interior of the tooth

pulp cavity

24

Contents of the pulp cavity

Connective tissue, blood vessels, nerves

25

Entrance/exit of the blood vessels/nerves in the pulp cavity

Apical foramen

26

Fibrous connective tissue that connects the neck of the tooth to the alveolus of the bone

Gingivae

27

Connects the cement and the periosteum of surrounding bone

Periodontal ligament

28

How many teeth do 2-3 y/o typically have?

20

29

How many teeth do adults typically have?

32

30

Divisions of the tongue

Root, body, apex

31

V-shaped groove at the boundary between the root and the body of the tongue

Terminal sulcus

32

Small pit at the midline of the terminal sulcus

Foramen cecum. (remnant of embryonic thyroglossal duct)

33

Midline of the dorsum of the tongue

Median sulcus

34

Divides the tongue into left and right halves

Median septum

35

Tongue receptors sensitive to touch

Filiform receptors

36

Shallow fossae on the superior aspect of the epiglottis

Epiglottic valleculae

37

General group of tongue mucsles that attach to bone

Extrinsic muscles

38

Large, fan-shaped muscle used for protusion of the tongue

Genioglossus

39

Arises from the body/greater wing of hyoid, depresses/retracts the tongue

Hyoglossus

40

Arises from the styloid process, participates in retraction/elevation of the tongue

Styloglossus

41

Arises from the palate, pulls the soft palate inferiorly

Palatoglossus

42

Muscles of the tongue that do NOT connect to bone

Intrinsic muscles

43

Muscles that control the tip of the tongue/help to retract the protruded tongue

Superior/inferior longitudinal muscles

44

Tongue muscles that arise from the septum and extend to the lateral edge of the tongue

Transverse group of muscles

45

Path of inferior alveolar artery

Branches off of maxillary artery, thru inferior alveolar canal, supplies lower teeth/gums/mandible

46

Superior alveolar artery path

From maxillary artery in infratemporal fossa, supplises posterior maxilla/teeth/gums

47

Supplies blood to anterior maxilla/teeth/gums

Infraorbital artery

48

Venous drainage of mouth

Into the pterygoid plexus then internal jugular vein

49

Path of lingual artery

Branches off of ECA, deep to hyoglossus, branches into dorsal/deep/sublingual/palatine tonsil
