Question

1. the semi - circular canals are sensitive to

a. pressure
b. low frequency sound
c. high frequency sound
d. body position
use the following graphic to answer question 48.
the human inner ear
note: both q and r are sensory nerves.

1. which description of the sensory nerves of the inner ear is correct?

a. r carries impulses from sound receptors.
b. r carries impulses from motion receptors.
c. q carries impulses from sound receptors.
d. q carries impulses from chemoreceptors.
hint: be able to match the mechanoreceptors, chemoreceptors, photoreceptors, and thermoreceptors with their respective structures, organs.

Explanation:

The semi - circular canals in the inner ear are part of the vestibular system which is responsible for detecting body position and balance, not sound or pressure. The cochlea in the inner ear contains sound receptors, and the nerve associated with it carries sound - related impulses. Q is likely related to the vestibular system (motion and body position) and R is related to the cochlea (sound).

Answer:

1. D. body position
2. A. R carries impulses from sound receptors.
