Select the correct statement about equilibrium.
A) Due to dynamic equilibrium, movement can be perceived if rotation of the body continues at a constant rate.
B) Cristae respond to angular acceleration and deceleration.
C) The weight of the endolymph contained within the semicircular canals against the maculae is responsible for static equilibrium.
D) Hair cells of both types of equilibrium hyperpolarize only, resulting in an increased rate of impulse transmission.

Question

Quizplus · Accepted Answer

Cristae are specialized receptor cells in the semicircular canals of the ear that respond to angular acceleration and deceleration. Option A is incorrect because dynamic equilibrium does not allow the perception of movement if the body is rotating at a constant rate. Option C is incorrect because the weight of the endolymph does not act against the maculae for static equilibrium, but rather the maculae themselves sense changes in the position of the head. Option D is incorrect because hair cells of both types of equilibrium (static and dynamic) depolarize or hyperpolarize depending on the direction of head movement, which leads to a change in the rate of impulse transmission.
