WebPostsynaptic Potentials. Postsynaptic potentials are changes in membrane potential that move the cell away from its resting state. For our purposes, postsynaptic potentials are … WebStages of an Action Potential. Plotting voltage measured across the cell membrane against time, the events of the action potential can be related to specific changes in the membrane voltage. (1) At rest, the membrane voltage is -70 mV. (2) The membrane begins to depolarize when an external stimulus is applied.

The all-or-none law is a principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fiber will fire. 1. According to the all-or-none law, there will either be a full response or no response at all ...

WebGraded potentials can be of two sorts, either they are depolarizing or hyperpolarizing (Figure 1). For a membrane at the resting potential, a graded potential represents a change in that voltage either above −70 mV or below −70 mV. Depolarizing graded potentials are often the result of Na+ or Ca2+ entering the cell. WebGraded potentials and action potentials are the way in which the stimulus in the body are received, transmitted and integrated into the nervous system in the body. The graded potential is...
