  3. The Anatomical Divisions of the Nervous System • Brain • Central Nervous System (CNS) • Peripheral Nervous System (CNS) • Spinal cord • It consists of the brain and spinal cord enclosed by cranium and vertebral column. • Nerves • Ganglia • It is all the nervous system except the brain and spinal cord. • It consists of nerves and ganglia. It is responsible for integrating, processing and coordinating sensory data and motor commands. It deliveries sensory information to the CNS and carries motor commands to peripheral tissues and system. Nerve: It is a bundle of nerve fibers (axons) wrapped in fibrous connective tissue. It is a bundle of nerve fibers (axons) in the CNS (white matter). Tract: • It is a concentration of neuron cell bodies in the CNS (gray mater). Nucleus: • It is a knot-like swelling in a nerve where neuron cell bodies are concentrated. Ganglion:
