Final answer:
The statement is True; dynamic equilibrium receptors in the semicircular canals respond to changes in angular motion, such as acceleration or deceleration, but not to constant velocity.
Step-by-step explanation:
The response of dynamic equilibrium receptors is indeed a reaction to changes in angular motion, making the statement True. These receptors, located in the fluid-filled semicircular canals of the inner ear, are sensitive to angular acceleration and deceleration. The receptors in question are known as mechanoreceptors, which are sensors in the body modified to respond to mechanical disturbances. They consist of hair cells that are stimulated by the movement of fluid within the canals when the head experiences angular motion such as turning or tilting. It is the change in velocity, rather than the constant motion, that triggers the sensory response. This is crucial for maintaining balance and orienting oneself in three-dimensional space
