Which of the following is true of receptors for dynamic equilibrium?
a) the receptors for dynamic equilibrium are located in the vestibule of the ear.
b) the receptors for dynamic equilibrium are not stimulated by head movement.
c) the receptors for dynamic equilibrium are called maculae.
d) the receptors for dynamic equilibrium respond to rotational forces.

The correct answer is option D.

Explanation:

Dynamic equilibrium refers to the sense, which interprets angular acceleration in the three-axis of rotation that when combined provides a sense of equilibrium when movement takes place. The receptors for dynamic equilibrium are known as ampulla, maculae are the receptors of static equilibrium.  

The movement of the head does stimulate dynamic equilibrium receptors, as these receptors are situated in the inner ear that moves with the head. The receptors for dynamic equilibrium are situated in the semicircular canals. The receptors for dynamic equilibrium react to rotational forces, as the receptors are located on the three-axis, thus, they can detect rotation, that is, angular momentum.  

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
