BRAINCAKEMotor Neurones
Motor neurones carry electrical impulses from the central nervous system (CNS) to effectors. Effectors are muscles or glands that bring about a response, such as a muscle contracting or a gland secreting a hormone.
The cell body of a motor neurone lies inside the CNS, in the brain or spinal cord. It has many short dendrites that receive impulses from relay neurones or sensory neurones.
