ANATOMY

Detailed explanation-1: -The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

Detailed explanation-2: -Nervous tissue, present in both the CNS and PNS, contains two basic types of cells: neurons and glial cells.

Detailed explanation-3: -Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord.

Detailed explanation-4: -The two divisions of the PNS are the somatic nervous system and the autonomic nervous system. The somatic system includes the nerves that transmit motor and sensory information to and from the CNS. The autonomic system regulates automatic body functions including digestion and blood pressure.

Detailed explanation-5: -The main function of the peripheral nervous system is to connect the central nervous system to the limbs and organs, essentially serving as a relay between the CNS i.e. the brain and spinal cord and the rest of the body.
