Nervous System

By Kiyah Darden

Sensory Input, Integration, and Motor output are the major functions of the nervous system.

  1. Your endocrine system works closely with your brain and central nervous system to control the creation of specific hormones and enzymes. Your digestive and excretory systems work with the nervous system in both conscious and unconscious ways. The nervous system sends signals to your brain to make your body alert that something is wrong. For example , if you fall on your knee , your nervous systems sends signals to your brain to let your body know that you've been hurt.
  2. Epilepsy, in which abnormal electrical discharges from brain cells cause seizures
  3. Parkinson's disease, which is a progressive nerve disease that affects movement
  4. Multiple sclerosis (MS), in which the protective lining of the nerves is attacked by the body’s immune system
  5. Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a motor neuron disease which weakens the muscles and progressively hampers physical function
  6. Huntington's disease, which is an inherited condition that cause the nerve cells in the brain to degenerate
  7. Alzheimer's disease, which covers a wide range of disorders that impacts mental functions, particularly memory.  These are all diseases and disorders associated with the nervous system.
