Explanation: 

Detailed explanation-1: -Nerves have cells called neurons. Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons.

Detailed explanation-2: -The neurons carrying impulses from the brain to muscles are called motor neurons.

Detailed explanation-3: -A motor neuron sends an impulse to a muscle or gland, and the muscle or gland then reacts in response. Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon. A nerve impulse travels along the neuron in the form of electrical and chemical signals. The axon tip ends at a synapse.
