Question

use the following graphic to answer question 49. 49. within the ear, the transmission of air vibrations leading to sensory impulses would activate structures in which sequence? a. v, p, r, and t b. p, r, s, and t c. v, p, q, and s d. p, q, r, and s hint: observe the diagram critically to differentiate where s and t originate. the two main functions of the ear (balance and hearing) must be kept separate in this question.

Explanation:

Sound waves first hit the eardrum (V in the diagram). Then, the vibrations are transferred through the ossicles (P). After that, they reach the cochlea (R) where sensory - hair cells convert them into nerve impulses. The structures related to balance (S and T) are not part of the sound - transmission pathway for hearing. So the correct sequence for sound - related activation is V, P, R.

Answer:

A. V, P, R, and T
