Explanation:
Detailed explanation-1: -A motor neuron is a nerve cell that transmits impulses from the brain or spinal cord to a muscle or gland.
Detailed explanation-2: -A neuron sending a signal (i.e., a presynaptic neuron) releases a chemical called a neurotransmitter, which binds to a receptor on the surface of the receiving (i.e., postsynaptic) neuron. Neurotransmitters are released from presynaptic terminals, which may branch to communicate with several postsynaptic neurons.
