arytenoid

Question 2

Answer 2

thyroarytenoid
posterior cricoarytenoid
lateral cricoarytenoid
arytenoid

Question 3

functions of the muscle of the palate

Answer 3

tesnor palati: depresses/flattens and tenses palate; open Eustachian tube

palatoglossus:
depresses palate and elevates tongue; aids in swallowing

levator palati:
raises and closes palate

musculus uvulae:
pulls velum mass up and forward

Question 4

hard palate

Answer 4

forms the roof of the mouth and is shelf across alveolar processes

Question 5

soft palate

Answer 5

posterior portion of roof of mouth, lowers to allow air passage to nasal cavity

Question 6

physiology of swallowing

Answer 6

oral phase-voluntary
lips close and tongue spreads over palate

pharyngeal-involuntary
velum elevates and superior, middle pharyngeal constrictors contract, forcing food down

esophageal phase-involuntary
inferior pharyngeal constrictor contracts, sending food into esophagus and initiating peristalsis which moves food throughout the body

Question 7

areas you assess when doing oral peripheral exam and exercise used to asses them

Answer 7

face, lips, tongue, teeth, palate, cheek, kinesthetic awareness

Question 8

structures and functions of outer ear

Answer 8

pinna: visible projections from head
supportive framework of yellow elastic cartilage

external auditory meatus: ear canal
from pinna to tympanic membrane
slants down to allow drainage

Question 9

lining of external auditory meatus contains

Answer 9

cilia
sebaceous glands: oils that lubricate skin
ceruminous glands: produce cerumen (earwax)

Question 10

tympanic membrane

Answer 10

ear drum; pearl-grey in color

-has a cone of light that appears as a white reflection in the lower quadrant
-malleolar stria is visible as a white streak
-funnel shape with malleus attached to apex

Question 11

ossicles of middle ear

Answer 11

bones of the middle ear

malleus
incus
stapes

Question 12

malleus

Answer 12

“hammer”

transmits vibrations from tympanic membrane to incus

parts:
head, neck, manubrium, anterior process, lateral process

Question 13

incus

Answer 13

anvil

transmits vibrations from malleus to stapes

parts:
body, short process, long process, and lenticular process

Question 14

stapes

Answer 14

stirrups

transmits vibration from incus to oval window

parts:
head neck, two crura, and a footplate

Question 15

muscles of middle ear

Answer 15

tensor tympani
stapedius

Question 16

Eustachian tube

Answer 16

opening slightly elevated off of floor of tympanic cavity to pharyngeal orifice of nasopharynx

35-38 mm
osseous- 12 mm (open)
cartilaginous- 18-24 mm (folded tube)

function: equalize pressure in middle ear and drain fluid

Question 17

structures in inner ear

Answer 17

vestibular system organs:
vestibular aqueduct
semi circular canals
utricle and saccule

hearing portion:
cochlea
scala media (cochlear duct)
