Detailed explanation-1: -Nerves of the PNS. The peripheral nervous system comprises thick bundles of axons, called nerves, carrying messages back and forth between the CNS and the muscles, organs, and senses in the body’s periphery (i.e., everything outside the CNS).
Detailed explanation-2: -The spinal cord carries messages back and forth between the brain and the nerves that run throughout the body.
Detailed explanation-3: -Messages, in the form of electrical impulses, constantly travel back and forth between the brain and other parts of the body. A special cell called a neuron is responsible for carrying these messages. There are about 100 billion neurons in the human brain.
Detailed explanation-4: -Neural pathways are groups of nerve fibers which carry information between the various parts of the CNS. Neural pathways that connect the CNS and spinal cord are called tracts.
Detailed explanation-5: -How is information carried to and from the CNS and the PNS? The afferent division carries sensory data from the PNS to CNS and the efferent division carries motor signals from the CNS to PNS.
