Flashcards in Head & Neck Deck (29):
1

What muscle closes the inferior aspect of the jaw?

Mylohyoid (mandible - hyoid bone)

2

Foramen caecum

apex of sulcus terminalis; remnant of the duct that forms the thyroid gland

3

Unilateral damage to the hypoglossal nerve presents as

protrusion of the normal side but not the affected side - tongue deviates towards the side of the lesion

4

Inferior alveolar nerve is a branch of

Mandibular (V3)

5

Superior alveolar nerve is a branch of

Maxillary (V2)

6

The duct of the parotid gland passes

anterior to the masseter

7

The duct of the parotid gland opens into

the vestibule between the lip and the gum at the upper 2nd molar

8

What are the 3 salivary glands?

parotid, sublingual, and submandibular

9

What is the position of the submandibular gland?

Wraps around the free lateral edge of the mylohyoid muscle

10

Where does the duct of the submandibular gland travel?

From the superior internal portion into a papilla lateral to the frenulum

11

Where is the sublingual gland?

lateral to the tongue in the floor of the mouth under the mucosa

12

Where does the sublingual gland open to?

Mucosa of the floor of the mouth lateral to the tongue

13

Where does the palatine tonsil sit?

Between the palatoglossal and palatopharyngeal arches on the lateral wall of the oropharynx

14

What is the function of the soft palate?

Closes off the nose during swallowing, coughing, and suction (elevation); seals off the oral cavity (depression) to allow breathing while chewing

15

The soft palate is attached to

the horizontal plate of the palatine bone

16

What is Waldeyer's ring?

incomplete ring of lymphoid tissue (tonsils) around the oral and nasal cavities; first line of defence; primes immune system in early life

17

What comprises Waldeyer's ring?

pharyngeal, tubual, palatine, and lingual tonsils

18

What forms the roof of the oral cavity?

Palatine process of maxilla and horizontal plate of palatine bone, soft palate, uvula

19

What forms the floor of the mouth?

Mylohyoid, digastric, geniohyoid muscles

20

Sulcus terminalis

divides tongue into posterior 1/3 and anterior 2/3

21

Valate papillae

anterior to sulcus terminalis

22

Foliate papillae

sides of tongue

23

Fungiform papillae

tongue

24

Where are the taste buds?

Around the bases of the fungiform papillae

25

Where are the lingual tonsils?

Posterior tongue

26

What are the 4 types of teeth?

2 each: incisors, canines, premolars, molars (3rd molars are wisdom teeth)

27

What is the nerve supply to the upper teeth?

Superior alveolar (V2)

28

What is the nerve supply to the lower teeth?

Inferior alveolar (V3)

29

Pain in the lower teeth can refer to

External auditory meatus via posterior auricular branch of V3
