Question

Quizplus · Accepted Answer

Receptors are specialized cells or structures that respond to various physical or chemical changes in their environment, such as changes in light (in the case of the eye) or changes in temperature (in the case of the skin). They are not responsible for carrying impulses from the CNS (B), nor are they only found at the peripheral endings of efferent neurons (C). Additionally, receptors can be found in both the somatic and autonomic nervous systems, so D is also incorrect.
