  2. Why is it important??? • Communicate information and processes to causes it reaction in other parts of the body • A network that relays messages back and forth • Controlling different parts of your body like - breathing - digestion - sweating - shivering - many more! • processing the nerve impulses

  3. Spinal Cord - runs along the dorsal side of your body - contains cell bodies & dendrites Components of the Nervous System • Brian - cerebrum - cerebellum - brain stem - pituitary gland - hypothalamus

  4. Dendrites receives info from another cell & transmit the message to the cell body Cell body - nucleus - mitochondria Axon- conducts messages away from the cell body Anatomy and Physiology • Neuron is the functional unit • We have 100 billion neurons in our BRAIN alone.

  5. The ANS • Controls “vegetative” process & adaptation of stress • Effects the smooth & cardiac muscles & Exocrine Glands • Neurotransmitters Acetylcholine, Norepinephrine, & Dopamine • Hormone: Epinephrine (EPI)

  6. The PNS • Digestion and other GI & urinary tract functions, and many more! • “Targets” the activation of structures under PNS control • All PNS activity is accomplished, physiologically • It’s the peripheral nervous system

  7. The SNS • Mainly controls all cardiovascular functions-blood pressure & blood flow • The sympathetic branch of ANS uses two neurotransmitters. ACH and norepinephrine plus a hormone: epinephrine to control its target. • It’s sympathetic nervous system

  8. The CNS • Central (CNS) – The Brian and The Spinal Cord • Sympathetic-is a branch of the autonomic nervous system along with the enteric nervous system and parasympathetic nervous system -active during times of stress • Parasympathetic- serves as a slow heart rate, increase the intestinal & gland activity, & relaxes the sphincter muscles

  9. Name Fact 1 Fact 2 Fact 3 Huntington Disease Autosomally- inherited, people who have it fidget which develops into jery, choreiforn movements Leads to clementia and usually death. High thoughts of suicide Huntington patients, ratio 40:1, normal people its 160:1 Weber syndrome Due to damage to the structures at the base of the midbrain including the 3rd cranial nerve Characterized by complete 3rd neverpasy & associated with contralateral hemipelagia common causes: aneurysm in the posterior parts of the circle of the willis, tumor, & occasion vessels Disease & Disorder

  10. Weber Syndrome Pictures of... • Huntington Disease

  11. Name Fact 1 Fact 2 Fact 3 Locked-in syndrome Due to stroke, tumor, or trauma to the ventral part of the costrel pons Lesions there render the individual, unable to speak & incapable of facial movements Looks as if in a coma, but you can move your eyes Walsenburg Syndrome Difficulty in swallowing & hoarseness due to paralysis of the ipsilateral vocal cord Some cases, taste may be affected in the ipsilateral part of the tongue Likely to be loss of pain temperature sensation on the ipsilateral face Diseases & Disorders tongue

  12. Locked-in Syndrome Walsenburg Syndrome Pictures of…

  13. Drugs & Alcohol • Alcohol is a centeral nervous system depressant • Alcohol is a very small molecule and is soluble in “lipid” and water solutions because of these properties alocohol gets into the blood streamilery easily & also crosses the blood brian barrier
