Answer 1

Answer: (D)

Vestibular apparatus are the inner ear structures that are associated with balance and position sense. It comprises of two components: the semicircular canal system, which indicate rotational movements; and the vestibule, which indicates linear accelerations. The vestibular system sends signals primarily to the neural structures, that control eye movement, and to the muscles to keep upright.
