Phyl 141 Nervous System Action Potentials Ion Movement Youtube Guest appearance by drake!. Starts off with resting membrane potential 1. graded potential reaches threshold—action potential is triggered 2. depolarization—sodium ions rush in via sodium channels, making the cell more positive 3. repolarization—too much positive ions in the cell, potassium ions are pushed out via potassium channels 4. Ion channels are membrane proteins that facilitate and regulate the movement of ions, such as na , k , ca 2 and cl through the cell membrane. these channels play a key role in essential cell functions including generation of action potentials and graded membrane potentials in neurons as well as synaptic communication between neurons. Phyl 141 | nervous system | saltatory & continuous propagation action potentials 2 voltage gated ion channels. 004 ion channels: proteins in the membrane of.
