Detailed explanation-1: -An effector is a part of the body which can respond to a stimulus according to the instructions sent from the nervous system (spinal cord and brain). Example: Glands and muscles.
Detailed explanation-2: -An effector is a part of the body that responds when the receptor cells send out signals to the central nervous system. The responses made by the effectors, such as the contraction of a muscle or the release of a particular hormone, are made as a result of the stimulation received by the receptor cells.
Detailed explanation-3: -There are two types of effectors, the muscles (also called “motor effectors") and exocrine glands (also called “secretory efectors"). All effectors are stimulated by nerves ie are “innervated". The nerves are called cranial nerves if they exit from the skull or spinal nerves if they exit from the spinal cord.
Detailed explanation-4: -The two types of effector organs are the muscles and glands. These are stimulated by nerves in response to the stimuli. The muscles are called motor effectors while the glands are called secretory effectors.
