Detailed explanation-1: -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: -The three primary roles of the spinal cord are to send motor commands from the brain to the body, send sensory information from the body to the brain, and coordinate reflexes. The spinal cord is organized segmentally, with thirty-one pairs of spinal nerves emanating from it.
Detailed explanation-3: -The spinal cord comprises three parts: the cervical (neck), thoracic (chest), and lumbar (lower back) regions. Three layers of tissue protect the spinal cord: the dura mater, arachnoid mater, and pia mater.
