do graded potentials occur in the axon
show more I'm studying graded and action potential...my teacher says the graded potential originates in the dendrite (the sodium coming in) but that graded potentials summate in the axon hillock, forming an action potential (if threshold is reached) How does the graded potential from the dendrite reach the axon... show more I'm studying graded and action potential...my teacher says the graded potential originates in the dendrite (the sodium coming in) but that graded potentials summate in ...
A stimulus-caused local change in membrane potential that does not lead to an action potential. 1. Most graded potentials occur in the cell body before the axon hillock. 2. Some graded potentials occur in cells that are not able to produce action potentials. because they donât have voltage gated ion channels that completely open and so they. donât have have a threshold potential.
