1

Which muscles form the floor of the mouth?

Mylohyoid

Geniohyoid

2

What is the innervation of the geniohyoid muscle?

C1 spinal nerve fibres

(travel alongside hypoglossal nerve)

3

What is the innervation of the mylohyoid muscle?

CN V3

4

What are the three bilateral pairs of major salivary glands?

  1. Parotid
  2. Submandibular
  3. Sublingual

5

What is the function of minor salivary glands?

Basal secretion of saliva to keep mouth moist

6

Where does the submandibular duct enter the oral cavity?

Floor via lingual caruncle

7

What is the innervation to sublingual salivary gland?

Facial nerve (CN VII)

8

What is the innervation to the submandibular salivary glands?

Facial nerve (CN VII)

9

What is the innervation of the parotid gland?

Auriculotemporal nerve (branch of CN V3)

(glossopharyngeal nerve supplies otic ganglion which supplies auriculotemporal nerve)

10

Where does the submandibular gland secrete saliva?

Lingual caruncle

11

What innervates the submandibular glands?

Facial nerve

(Via chorda tympani which joins with lingual nerve, a branch of CN V3)

12

What innervates the sublingual glands?

Facial nerve

(Via chorda tympani which joins with lingual nerve, a branch of CN V3)

13

Which types of lingual papillae are related to taste?

  1. Vallate
  2. Fungiform
  3. Foliate

14

Which type of papillae on the tongue is associated with toch and temperature?

Filiform

15

What are the lymphoid nodules on the mucosa of the posterior tongue collectively known as?

Lingual tonsil

16

By which other name is the submandibular duct called?

Wharten's duct

17

What provides general sensation to the anterior 2/3rd of the tongue?

Lingual nerve

(branch of CN V3)

18

What provides taste sensation to the anterior 2/3rd of the tongue?

CN VII

(via chorda tympani)

19

What provides tatste and general sensation to the posterior part of the tongue?

CN IX

20

How do thyroid swellings move on swallowing?

Superiorly then inferiorly

21

What are the 4 extrinsic muscles of the tongue?

  1. Palatoglossus
  2. Styloglossus
  3. Genioglossus
  4. Hyoglossus

22

What is the motor innervation of the extrinsic muscles of tongue?

All CN XII except palatoglossus (pharyngeal plexus (from CN X))

23

Where do the rootlets of the hypoglossal nerve attach to the brain?

Medulla oblongata

24

What is the extracranial pathway of the hypoglossal nerve?

Descends in neck lateral to the carotid sheath

Passes anteriorly at the level of the hyoid bone towards lateral tongue

25

How can CN XII be clinically tested?

Stick out tongue

(tongue tip should remain in the midline upon protrusion)

(if it deviates to one side, that is the side with the dysfunctional nerve)

26

Arteries pass ________ to the hyoglossus and nerves pass _________ to the hyoglossus

Arteries pass medial to the hyoglossus and nerves pass lateral to the hyoglossus

27

Which bones form the hard palate?

  1. Palatine processes of maxilla
  2. Palatine bones
  3. Sphenoid bone

28

How do the epithelia of the hard and soft palate differ?

Hard - Keratinised stratified squamous

Soft - Non-keratinised stratified squamous

29

Name the muscles associated with the soft palate

  1. Tensor veli palatini
  2. Palatopharyngeus
  3. Palatoglossus
  4. Musculus uvulae
  5. Levator veli palatini

30

What is the innervation of all of the muscles of the soft palate and what is the exception?

CN X

Tensor veli palatini - CN V3
