WebbWhat distinguishes nerve cells and other excitable membranes (e.g., muscle cells) is that they are capable of changing their resting potential. In the case of nerve cells, for integrating information and transmitting information, whereas, in the case of muscle cells, for producing muscle contractions. Action potentials. Webb“Cell signalling is the process by which cells communicate with other cells within their body or with the external environment.” Cell signalling occurs by several distinct pathways. Multicellular organisms need cell signalling to regulate different functions. E.g. nerve cells in coordinate with muscle cells to help in body movement.
