Anatomy and Physiology Review
The nervous system is the basis for all human function. It is the center of thinking, memory, judgment, sensation, movement, cognition, communication, behavior, and personality.
In addition to its direct control over many processes, the nervous system innervates many other body systems.
The major divisions of the nervous system are the Central Nervous System and the Peripheral Nervous System.
The brain and spinal cord are the major components of the Central Nervous System.
The Peripheral Nervous System is composed of 12 pairs of cranial nerves, 1 pairs of spinal nerves and the autonomic nervous system.
