2. Neurotransmitters

2.1. Acetylcholine

2.1.1. Def: Most common type of neurotransmitter. This one activates muscles that help the body move. Also involves learning and memory.

2.1.2. Too much: Paralysis.

2.1.3. Too little: Memory loss.

2.2. Dopamine

2.2.1. Def: Pleasure neurotransmitter that is in nerve cells and helps with thinking and planning.

2.2.2. Too much: Schizophrenia.

2.2.3. Too little: Parkinson's disease.

2.3. Def: Chemical substances that are stored in very tiny sacs within neuron's terminal buttons and involved in transmitting info across a synaptic gap to the next neuron.

2.4. Serotonin

2.4.1. Def: Pleasure neurotransmitter in digestive system and blood platelets. Controls sleep and mood.

2.4.2. Too much: Seizures.

2.4.3. Too little: Depression.

2.5. Norepinephrine

2.5.1. Def: Naturally occurring chemical in the body that acts as both a stress hormone and neurotransmitter. It controls alertness and fires neurons.

2.5.2. Too much: Manic states.

2.5.3. Too little: Depression and Bipolar.

3. Parasympathetic Nervous System

3.1. Def: The part of the autonomic nervous system that calms the body.

4. Central Nervous System (CNS)

4.1. Def: The brain and spinal cord in a complex organization of nerve tissues.

4.2. Connections: Uses neurotransmitters to communicate.

5. Spinal Cord

5.1. Def: A long tubular bundle of nerve fibers.

5.2. Connections: Part of the CNS and is connected to the brain.

6. Neuron

6.1. Def: One of two types of cells in the nervous system; neurons are the nerve cells that handle the info-processing information.

7. Axon

7.1. Def: The part of the neuron that carries info away from the cell body toward other cells.

8. Dendrites

8.1. Def: Treelike fibers projecting from a neuron, which receive info and orient it toward the neuron's cell body.

9. Myelin Sheath

9.1. Def: A layer of fat cells that encases and insulates most axons.

10. Peripheral Nervous System (PNS)

10.1. Def: The network of nerves that connects the brain and spinal cord to other parts of the body.

11. Autonomic Nervous System (ANS)

11.1. Def: The body system that takes messages to and from the body's internal organs, monitoring such processes as breathing, heart rate, and digestion.

12. Sympathetic Nervous System

12.1. Def: The part of the autonomic nervous system that arouses the body to mobilize it for action and thus is involved in the experience of stress. Fight or flight.
