module 22 (done)

Question 1

bony labrinth

Answer 1

series of canals embedded within the temporal bone

contains perilymph

Question 2

membranous labyrinth

Answer 2

endolymph

Question 3

round window

Answer 3

covered by a membrane that contains perilymph within the bony labyrinth
remaining energy to be dissipated and preventing echoes within the cochlea

Question 4

oval window

Answer 4

located at the beginning of a fluid-filled (perilymph) tube within the cochlea called the scala vestibuli

Question 5

scala vestibuli

Answer 5

extends from the oval window, traveling above the cochlear duct

Question 6

scala tympani

Answer 6

uppermost tip of the cochlea –> curves over the top of the cochlear duct
–> still perilymph tube, scala tympani, returns to the base of the cochlea, this time traveling under the cochlear duct –> ends at round window

Question 7

cochlear duct

Answer 7

contains endolymph
spiral organs of corti –> transduce waves into neural signals

Question 8

basilar membrane

Answer 8

organs of corti lay ontop

Question 9

which things monitor head position?

Answer 9

utricle and saccule

Question 10

head movement?

Answer 10

semicircular canals

Question 11

otolithic mebrane

Answer 11

viscous gel and has otoliths ontop

Question 12

macula

Answer 12

utricle and saccule are both largely composed of macula tissue

Question 13

cupula

Answer 13

cups the hair cells in the semicircular canals

Question 14

auditory pathway

Answer 14

cochlear nerve –> vestibulocochlear nerve —> pons –> MGN of thalamus

Question 15

vestibular pathway

Answer 15

CN VIII –> brainstem –> integrate sensory info and relay it to spinal cord, cerebellum, cerebrum and many CN
