3 Function of the Nervous System 1.Control center for all body activities 2.Responds and adapts to changes that occur both inside and outside the body (Ex: pain, temperature, pregnancy) 3.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: 1.Central nervous system (brain and spinal cord). 2.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: 1.Cerebrum 2.Cerebellum 3.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 1.Cryosurgery (An instrument with a nozzle is used to spray liquid nitrogen or liquid carbon dioxide to freeze and destroy abnormal tissue) 2.spinal puncture, spinal tap 3.vagotomy (removal of, or at least severing) of part of the vagus nerve

12 Some abbreviations EEG: electro encephalon gram LP: lumber puncture MS: multiple sclerosis CNS: Central nervous system CVA: cerebra vascular accident ICP: intra cranial pressure MRI: Magnetic resonance imaging

13 ANS: autonomic nervous system CP: Cerebral palsy CT Scan: computed tomography TIA: transient ischemic attack
