Nerve pathways that carry motor information away from the central nervous system.

Spinal Reflex

Central Nervous System (CNS)

Part of the nervous system that consists of the brain and spinal cord.

Peripheral Nervous System (PNS)

Part of the nervous system that consists of all the nerves outside the CNS.

Somatic Nervous System

Part of the nervous system responsible for voluntary movements.
