GENERAL HISTOLOGY

Detailed explanation-1: -An effector acts in special ways in response to a nerve impulse. Effectors in multicellular organisms are either glands or muscles. In humans, these effectors may either be muscles, which contract in response to neural stimuli, or glands, which produce secretions.

Detailed explanation-2: -Once the receptor has detected a stimulus, it sends a message to the central nervous system (CNS). The CNS then sends a signal to an effector which produces a response. An effector is a muscle or organ which acts in a certain way to maintain homeostasis despite the effects of the stimulus.

Detailed explanation-3: -Effectors include muscles and glands-that produce a specific response to a detected stimulus. For example: a muscle contracting to move an arm.
