The nerves that transmit impulses out of the brain or spinal cord to effectors, such as muscles and glands, are known as motor (efferent) nerves. These nerves carry signals from the central nervous system (CNS) to peripheral effectors, facilitating actions like muscle contraction and gland secretion. Specifically, the somatic motor nerves control voluntary muscle movements, while autonomic motor nerves regulate involuntary functions like heart rate and digestion.
