WebApr 8, 2024 · The resting membrane potential of cells varies depending on the cell type. For neurones, this typically sits between -50 and -75mV. ... An action potential begins at the axon hillock as a result of depolarisation. During depolarisation, voltage-gated sodium ion channels open due to an electrical stimulus. As the sodium ions rush back into the ... WebAxon hillock. Red labeled is pointing directly at the axon hillock. The axon hillock is a specialized part of the cell body (or soma) of a neuron that connects to the axon. It can be identified using light microscopy from its appearance and location in a neuron and from its sparse distribution of Nissl substance. [1]
