What do dendrites do?
Receive/listen to messages from other cells.
What do axons do?
Send messages away from the cell body to other neurons/muscles/glands.
What does Myelin Sheath do?
Covers the axon of some neurons; it enables greater transmission speeds.
Multiple Sclerosis
Degenerative myelin sheath
-Trouble with muscle correlation
-Transmission speeds of signals changes all the time.
Action Potential
Neural impulse/ionic charge
What ions are found inside axons?
Negatively charged potassium
What ions are found outside axons?
Positively charged sodium
