Document Summary

Resting state - the other channels are mostly closed. At threshold, voltage gated channels open - sodium flows in. Falling phase - potassium flows out while sodium channels are closed. Decision is made at axon hillock - action potential starts as sodium ions move in. Sequentially moving - action potential goes in one direction, moves down axon. Axons have myelination - to go long distances, nerves are myelinated to. What is the end point of action potential. Emil dubois reymond - there are nerves in muscles. Muscles will responding in elecrical way in response to chemicals. Adrenal glands, tested adrenal gland extracts on blood pressure/ heart rate. Walter dixon - amanita muscari - slows down heart rate - make us releaxed. Same as activating vagus nerve - make you feel invicinciple. Electrical stimulation of vagus nerve - slows down heart rate. Sir henry dale - isolated acetylcholine from the ergot fungus. Disruptions between neruons must be chemical not electrical.
