Front 6

What are the four ganglions associated with parasympathetic of cranial nerves

Back 6

Ciliary ganglion [CN 3]
Submandibular ganglion [CN 7]
Otic ganglion [CN 9]

Front 7

Function of chorda tympani

Back 7

- Some fibers will provide parasympathetic stimulation to glands below the oral fissure
- Some fibers will provide taste sensation to the anterior 2/3 of the tongue

Front 8

Where did preganglionic fibers of CN 9 exit the skull

Back 8

Through foramen ovale

Front 9

BB Week 7

Back 9

Tongue, pharynx, larynx

Front 10

In the neutral position, are the soft palate and epiglottis open or closed

Back 10

both open, allows passage of air from nose and mouth into trachea
- soft palate partially elevated

Front 11

What occurs in oral cavity during chewing and breathing (through nose).

Back 11

- back of tongue elevated
- palate depressed
- oropharyngeal isthmus closed

Front 12

What happens during swallowing

Back 12

- Opening between nasal and oral parts of the phaynx closed by soft palate
– Larynx and hyoid pulled up and forward resulting in opening the esophagus
– Epiglottis closed over the laryngeal inlet
– Oropharyngeal isthmus open

Back 14

anterior: VII
posterior: IX

Front 15

Motor to anterior and posterior tongue

Back 15

anterior AND posterior: XII

Front 16

Which muscle is responsible for moving the tongue left and right

Back 16

Genio-glossus muscle

Front 17

Which muscle is responsible for retraction of the tongue

Back 17

Hyo-glossus and Styloglossus

Front 18

Veins draining tongue

Back 18

- deep lingual vein (drug absorption)
- sublingual vein

Front 19

Motor innervation to palatoglossus

Back 19

X (pharyngeal branch)

Front 20

What are the longitudinal muscles of the palate

Back 20

- stylophayngeus m.
- palatophayngeus m.
- salpingophayngeus m.

Front 21

Which muscles are responsible for elevation of the palate

Back 21

Longitudinal palatal muscles (stylo-, palato- and salpingo- pharyngeus)

Front 22

Role of salpingophayngeus muscle

Back 22

- elevates pharynx
- opens eustacian tube --> equalization of pressure with middle ear
- swallowing reopens tube to allow air to re-enter

Front 23

Sensory and motor supply to pharynx

Back 23

phayngeal branches of:
sensory: V2, IX, X
motor: IX*, and X

* only to salpinopharyngeus m.

sensory: IX
motor: X

Nerves supplying larynx

Back 25

sensory and motor by X (laryngeal branch)

Back 26

Tensor veli palatini m. (tenses soft palate)

Levator veli palatini m. (elevates palate)

Front 27

Which muscle move the palate down

Back 27

Palatophayngeus m.

Front 28

The palato-glossal arch this form by which muscle

Back 28

palatoglossus m.

Front 29

The palatopharyngeus m. is form by which muscle

Back 29

palatophayngeus m.

Front 30

The soft palate muscles are innervated by which nerve(s)

Back 30

All muscles of soft palate are innervated by X
EXCEPT

tensor veli palatini - V3

Front 31

Functions of the palatoglossal muscles

Back 31

– Elevate the back of the tongue
– Move the palatoglossal arches of mucosa towards the midline
– Depress the soft palate
