Animal Cell Picture

Action potential is an event in which the membrane potential of a cell first increases and then decreases. It is a characteristic property of a number of animal cells namely, neurons, muscle cells and endocrine cells. Some plant cells also produce them. Neurons play a very crucial role in cell-to-cell communication. In beta cells of pancreas action potential is associated with the release of insulin. Plasma membrane has special type of voltage-gated ion channels for producing action potential. These channels remain closed when the membrane potential is close to the resting potential of the cell but if the membrane Read the rest of this entry »
