ANATOMY

Detailed explanation-1: -The nervous system is made up of the central nervous system and the peripheral nervous system: The central nervous system includes the brain and spinal cord. The peripheral nervous system includes the nerves that run throughout the whole body.

Detailed explanation-2: -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-3: -The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord.

Detailed explanation-4: -Your nerves consist of bundles of nerve cells, which have long, arm-like extensions called axons. The nerve cells and their axons twist and intertwine together to form nerve fibers. This is similar to how multiple strands of spun cloth fibers twist together to form sewing thread.
