Central Nervous System / Spinal Cord

The central nervous system is one of the two main divisions of the human nervous system . It integrates all nervous function and deals with the information to and from the peripheral nervous system .

movement , hunger , thirst , memory and emotions . The spinal cord contains various types of nerve fibers from the brain and act as a switching relay terminal for the peripheral nervous system

The spinal cord is the main pathway for the messages traveling between the brain and the rest of the body . It provides neuron and synapse networks to produce involuntary responses to sensory stimulation . It carries sensory information to the brain and motor information from the brain . Nerve cells of the body branch out to supply every muscle and particle of skin , as well as all of the internal organs . They carry messages from the periphery through the spinal cord to the brain Similar messages travel back from the brain to the nerve fibers in the muscles to initiate movement

Any damage in the spinal cord , may it be due to trauma from fall vehicular accidents and violence will result to a decline in the motor and sensory function of the body . Paralysis...
