Response – action performed by an effector
A response is any action performed by an effector arising from a signal from the nervous system.
The Rapid Response vehicle was drive by Action Man.
Responses usually take the form of a muscle contracting or relaxing to allow movement, or a gland contracting to release a hormone into the blood or digestive system.
That responses can happen both consciously (somatic) or without any thought (autonomic). Many body controls and functions are taken care of autonomically.
