Neurons or Nerve Cells

Neurons or Nerve Cells

1. They're the building block of the Nervous System.

2. Types: Bipolar, Uni-polar, Multi-polar, and Pyramdical Cell.

3. Soma or "Cell body" is a neuron's life support

4. Dendrites: receive messages to activate action potential.

5. Axon: Delivers messages to other neurons

6. Myelin Sheath: Fatty layer of tissue surrounding the neuron, in order to insulate the electricity inside the neuron from the outside.

7. Synapse: Small gap between the neurons. Process: 1) Axon terminal-- 2) Synaptic Gap -- 3) Receptor Sites

8. Extra neurons go back to the original cell in a process called "Re-uptake"

9. They cause motion and emotion.

10. They're connected to the brain and spinal cord.

11. Neurotransmitters change moods.
