  1. What is Alcohol? By: ShannenSolatan Leila Nevalasca Kay Mendoza

  2. ALCOHOL

  3. Alcohol Effects on the Nervous System Serotonin: • Increases the Serotonin levels in the brain, which is the reason of alcohol being addictive. Dopamine: • Increases the Dopamine levels, which also contributes to the addictive effect. GABA (gamma-aminobutyric acid) • Alcohol increases GABA activity, which inhibits the brain activity. Glutamate • The excitatory neurotransmitter, alcohol reduces glutamate activity, the result is slurred speech and discoordination.

  4. ALCOHOL - The blood stream absorbs the alcohol and the nervous system slows down dramatically. Short Term Effect • Poor vision • Slow reaction time • Reduced Coordination • Slower brain activity • Sleepiness • Slurred Speech • Vomiting

  5. ALCOHOL - The blood stream absorbsthe alcohol and the nervous system slows down dramatically. Long Term Effect • Brain cells die • Cancer • Hyperglycermia • Kidney Disease • Nervous Disorders • Coma • Death • Higher chance of heart attack/stroke

  6. COCAINE

  7. COCAINE - When it is used it interferes with the absorption of dopamine. Short Term Effect • Constricted blood vessels • Dilated pupils • Increased body temperature • Increased Heart Rate • Higher blood pressure Long Term Effect • Irregular Heart Beat • Heart Attack • Chest Pain • Respiratory Failure • Stroke • Seizures • Nausea • Death

  8. Using cocaine can damage a person's brain. The use of cocaine can cause strokes by constricting blood vessels to the brain. Cocaine also increases the concentration of dopamine in the synapse.

  9. Functions of the nervous system • Sensory Input - by receptors, the nervous system monitors changes in the environment both outside and within the body • Integration – the CNS (Central Nervous System) processes the sensory inputs, interprets and integrates them • Motor Output – the nervous system triggers a response by stimulating the effector organs; muscles and glands.

  10. The main organs of the nervous system are the brain and the spinal cord.

  11. -Severe intoxication could lead to many things. -It can can further deteriorate with disorder of consciousness and of the respiratory cardiac centers -lead to unconsciousness or severe instability, respiratory failure, or cardiac arrest. Severe intoxication could also lead to disorder of the reflexes. it could also lead to hypothermia. Hypothermia is a condition in which the core temperature drops below the required temperature for normal metabolism and body functions.

  13. Did you know? - The impulses of the nervous system are 0.1 volts (100 millivolts) strong. - The average adult human brain weighs just below three pounds. - There is a character from the cartoon "The Powerpuff Girls" with a similar name to a certain part of the brain: the cerebellum (Sara Bellum)

  14. Drugs - Good or bad?
