Bone conduction responses in Audiogram # 2 indicate that cochlear function is normal. True False
Added by Blanca P.
Step 1
Bone conduction audiometry assesses the function of the inner ear (cochlea) by bypassing the outer and middle ear. If bone conduction thresholds are within normal limits, it suggests that the cochlea is functioning properly. Show more…

C. Hearing (True-False) 1. Sound waves may reach the cochlea through the skull bones as well as via the tympanic membrane. 2. The more hair cells sending impulses, the louder will be the sound sensation. 3. Pitch is determined by the part of the basilar membrane that is activated. 4. Bending of the hair cells causes the formation of impulses. 5. There is no cure for conduction deafness, but nerve deafness may often be corrected. D. Equilibrium Select the structures described by the statements below. ampulla otoliths crista ampullaris saccule macula utricle 1. Two portions of the membranous labyrinth containing sensory receptors for static equilibrium. 2. Sensory hair cells in ampullae of semicircular canals. 3. Hair cells stimulated by the movement of the otoliths. 4. Hair cells stimulated by the force of endolymph. 5. Sensory receptors for dynamic equilibrium. 6. Enlarged base of a semicircular canal. 7. Calcium carbonate crystals. E. Hearing Tests Record your results of the hearing tests. Rinne Test Left ear Right ear
