AP PSYCHOLOGY

Detailed explanation-1: -Alpha motor neurons (also called lower motor neurons) innervate skeletal muscle and cause the muscle contractions that generate movement.

Detailed explanation-2: -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-3: -Motor nerves also known as efferent nerves, carry impulses away from the brain or spinal cord to muscles and glands. Sensory nerves also known as afferent nerves, carry impulses from sensory receptors towards the brain.

Detailed explanation-4: -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.

Detailed explanation-5: -The motor (efferent) division carries motor signals by way of efferent nerve fibers from the CNS to effectors (mainly glands and muscles).
