E)utricle and saccule in the inner ear

Question

Quizplus · Accepted Answer

The semicircular canals in the inner ear detect rotational acceleration or deceleration of the head.

Answer: A and B 
 The external ear and middle ear are not involved in detecting rotational acceleration or deceleration of the head. The external ear collects sound waves and the middle ear amplifies and transmits these sound waves to the inner ear.

Answer: C, E 
 The cochlea in the inner ear is responsible for hearing and the utricle and saccule in the inner ear are responsible for detecting linear acceleration and head position. Neither of these structures are specifically involved in detecting rotational acceleration or deceleration of the head.
