Verified step by step guidance1
Understand that the vestibular apparatus is a part of the inner ear involved in balance and spatial orientation.
Recognize that the vestibular apparatus consists of structures such as the semicircular canals and the otolith organs (utricle and saccule).
The semicircular canals detect rotational movements of the head, which are angular accelerations.
The otolith organs (utricle and saccule) detect linear accelerations and the effects of gravity, helping to sense head position relative to gravity.
Conclude that the vestibular apparatus is responsible for detecting gravity and head movement, not sound waves, temperature changes, or light.
