Introduction:

Nerve cell is the structural unit of the nervous system. The nervous system is categorized into the central nervous system and the peripheral nervous system. The central nervous system contains the brain and the spinal cord. The spinal cord arises from the brainstem and runs up to the lumbar region of the vertebral column. The spinal cord provides spinal nerves that run toward the body parts and regulates the communication process between the central nervous system and the body parts.
