Select the correct statement about equilibrium. a) the weight of the endolymph contained within the semicircular canals agains the maculae is responsible for static equilibrium.
b) due to dynamic equilibrium, movement can be perceived if rotation of the body continues at a constant rate
c) cristae respond to angular acceleration and deceleration.
d) hair cells of both types of equilibrium hyper polarize only, resulting in an increased rate of impulse transmission.

cc) cristae respond to angular acceleration and deceleration.

Explanation:

The vestibular system is the sensory apparatus of the inner ear that acts to maintain body equilibrium, as well as to coordinate the position of the head and eye movement. The vestibular system consists of five distinct sensory organs: three semicircular canals (i.e., anterior, posterior, and lateral) which are involved in dynamic equilibrium; and the two otoliths (i.e., utricle and saccule), involved in static equilibrium. The crista ampullary (​plural: cristae) is the sensory organ located in the semicircular canals of the inner ear of vertebrates, which act to detect angular acceleration and deceleration. The cristae of the semicircular canals respond to the rotational movement and are responsible for dynamic equilibrium.
