2. Nervous system

3. Function of the Nervous System
Control center for all body activities
Responds and adapts to changes that occur both inside and outside the body (Ex: pain, temperature, pregnancy)
Carries electrical messages to and from the brain and spinal cord.
When the brain ceases functioning, the body dies.

4. Structures of the Nervous System
Nervous System is divided into:
Central nervous system (brain and spinal cord).
Peripheral nervous system (cranial nerves and spinal nerves)
Nerve is one or more bundles of impulse carrying fibers that connect the brain and spinal cord with body.

5. Central Nervous System
Neurons : microscopic nerve cells that make up the brain, spinal cord, and nerves
- 30,000 neurons can fit on a pinhead

6. Parts of the brain Brains (encephalo) divided into: Cerebrum
Cerebellum
Brainstem

8. Medical terms related to nervous system
Alzheimer disease: Brain disorder marked by deterioration of mental capacity
Epilepsy: Chronic brain disorder characterized by recurrent seizure activity.
Meningitis: Inflammation of the meninges (membranes surrounding the brain and spinal cord)
Multiple sclerosis: Destruction of the myelin sheath on nerve cells in the central nervous system , with replacement by hard tissues.

9. Diagnosis procedure
Cerebral angiography:
X-ray image of blood vessels in the brain after injection of contrast

10. Echoencephalography(C.C.G):
Record of the electrical activity in the brain
Computed tomography (C.T scan):
Cross-sectional x-ray images of the brain and spinal cord

11. Surgical therapeutic procedure
Cryosurgery (An instrument with a nozzle is used to spray liquid nitrogen or liquid carbon dioxide to freeze and destroy abnormal tissue)
spinal puncture, spinal tap
3.vagotomy (removal of, or at least severing) of part of the vagus nerve
