Unformatted text preview: inside the cell, more Na+ on outside of cell b. Stimulation occurs > neurotransmitter released > Na+ gates open c. Depolarization of the membrane > begins action potential d. Na+ gates close > cell leaks potassium e. Na+ - K+ pump is activated = active transport, needs ATP 4. Neurotransmitters a. Excitatory - Ach b. Inhibitory - GABA c. Threshold must be reached for AP (action potential) to occur d. Neurolemma = nerve cell membrane...
