1 You’ve Got Some Nerve!!! Exploring the depths of your nervous system! By: Rosaida Rosado & Becka Hoadrea

2 Why is it important? Controls senses essential to life, like breathing, movement, and coordinates parts of the body and organs.

3 Components of Nervous System

4 Types of Nervous Systems Nervous Systems: Central, Peripheral, Somatic, Autonomic, Sympathetic, and Parasympathetic. Central: Contains the brain and spinal cord. Peripheral: Sensory receptors, nerves, and motor endings. Somatic: Sensory neurons that help the joints and muscles. Autonomic: Motor system for exocrine glands. Sympathetic: Helps the body deal with stress. Parasympathetic: Conserve resources and maintain homeostasis.

5 Anatomy & Physiology Allows you to feel, and see, and move, and think… It keeps all the body functions harmonized. Brain is the control center. In charge of involuntary and voluntary movement.

6 Alcohol! Depressant on the Central Nervous System. Factors that effect the affect: age, gender, amount of food intake, body’s condition, and any other drugs or medications being taken. Effects include, but are not limited to: body relaxation, less tension, slows reflexes, impairs concentration, slur speech, alter emotions, cause drowsiness, vomiting, breathing difficulties, and in worst case, coma.

7 Alzheimer's disease- occurs in brain(confusion,restlessness, impaired speech, etc) ALS-occurs in spinal chord and brain(twitching, muscle cramps, fatigue, etc) MS-occurs in central nervous system(numbness weakness, dizziness, etc) Parkinson’s disease-occurs in the brain(tremors, slowness in movement, lack of balance, etc) Epilepsy and Seizures- occurs in the brain(jerking, stiffness, confusion, etc) Diseases and Disorders

8 Diseases & Disorders Alzheimer's: Affects the Brain. Deterioration and forgetfulness. Down Syndrome: Chromosomal disorder. Extra chromosome that causes developmental problems and a different appearance. Muscle Cramps: When the voluntary movements of the body have a spasm, then the muscle is affected and tightens, causing pain.

9 Marijuana! Contains over 400 chemicals that alter the CNS. THC is the main active ingredient in marijuana because it affects the brain by binding to and activating specific receptors, known as cannabinoid receptors. Scientists have concluded that it can have an effect on brain functions because the chemicals tend to alter the chemical makeup of your brain.

10 Heroin! Heroin begins to work in 7 to 8 seconds when it is injected through a vein. If it is injected through a muscle, then the effects take longer, about 5 to 8 minutes. The main ingredient is opium. Most users inject heroin into their veins. Addiction is quick because the drug instantly is able to get to the Nervous System and change the brains chemical makeup.
