WebSelect all that apply. (select all that apply) It refers only to a small patch of the membrane; other parts of the neuron can still be stimulated while a small area of it is refractory. It occurs during the depolarization and repolarization phases of the action potential. No stimulus of any strength will trigger a new action potential. WebAn action potential is where things really become interesting and exciting—no pun intended; but remember that only excitable tissues can experience action potentials. An action …
WebGlutamate action is terminated by two mechanisms. Reuptake of glutamate molecules into the presynaptic terminal can occur, or glutamate can be transported into nearby glial cells.
