First We Will Discuss ‘ORGANIZATION & CELLS OF NERVOUS SYSTEM’ then we will talk about ‘Overview of Central nervous system’ [CNS]. 2. ORGANIZATION OF NERVOUS SYSTEM. THE AUTONOMIC NERVOUS SYSTEM. The autonomic nervous system (ANS) is a motor or efferent system which connects the central nervous system with all smooth muscle, cardiac muscle and gland cells of the body.. 85 to 180 billion neurons in the human brain?! How does anything get done?. CENTRAL NERVOUS SYSTEM. Brain and spinal cord.. PERIPHERAL NERVOUS SYSTEM (PNS). Def. : all nerves that lie outside the brain and spinal cord.
