Web17 nov. 2024 · History. 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 ... WebA graded potential change that causes the resting membrane potential to change from -70 mv to -80mv is _____. an inhibitory postsynaptic potential (IPSP) What type of synapse …
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 result from the opening of mechanical, or ligand-gated channels. Graded potentials can be summed, or added on top of each other to increase the change. Stated …
