Neuroeffector junction

Neuroeffector junction

A neuroeffector junction is the site where a motor neuron releases a neurotransmitter to affect a target (non-neuron) cell. This junction functions like a synapse. Somatic efferent motor neurons innervate skeletal muscle, and are always excitatory. Visceral efferent neurons innervate smooth muscle, cardiac muscle, and glands, and may be either excitatory or inhibitory. Neuroeffector junctions are known as neuromuscular junctions when the target cell is a muscle fiber.
