The central nervous system

The Nervous System The central nervous system consists of the brain and the spinal cord. This is the most complex of the body’s organs and it is the body’s communication system. Nerves that branch out from the spinal cord are called the peripheral nervous system. The subdivisions of the peripheral nervous system are called somatic and autonomic. These functions control breathing, digestion, and muscle movement. The nervous system enables the body to respond to light, sound, and changes in temperature. Migraine headaches are a disease of the nervous system. Migraines tend to be more common in women than in men and begin earlier on in life. The pain is usually moderate to severe on one or both sides of the head plus it can cause sensitivity to light, sounds, and smells, and may cause nausea and vomiting. In addition, they may cause numbness, dizziness, and blurred vision. Some causes are believed to be hereditary, lack of diet, lack of sleep, weather changes, hormone changes, and stress just to name a few. Some treatments for migraines include analgesics (aspirin and acetaminophen), nonsteroidal anti-inflammatory drugs (NSAIDs), ergotamine, and metoclopramide just to name a few. Most Triptans have a half-life of about 2 hours. Riztriptan is available in tablet form or rapid-dissolve form. In addition, lying down in a cold dark room with no noise can be helpful.
