The membrane "behind" the AP is in a refractory state and can't support the generation of a new AP. The membrane "ahead" of the AP hasn't been activated yet, so it can support an AP. What direction to APs usually propagate? (p. 130) For vertebrate neurons, the spike initiation zone is at the soma and APs propagate away from the soma.

The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. In bacterial and plant cells, a cell wall is attached to the plasma membrane on its outside surface. The plasma membrane consists of a lipid bilayer that is semipermeable.
