Document Summary
Communication been cells in direct contact review. Gap junctions between adjacent cells that let chemical and electrical signals pass between cells. The electrical signals are ion currents, involve ions. Involves the binding of one surface molecule on one cell into another surface molecule on another cell. Typically proteins and glycoproteins, can involve lipids as well. Crucial for the development of the nervous system. Local and long-distance cell communication by chemical signaling in animals. One cell releases a chemical and this chemical signal reacts on adjacent cells that are capable of responding to it. The chemicals that are released are only release at the synapse; they only in uence the adjacent target cell. The hormone chemicals enter the blood and causes a response in any cell that is capable of responding to it. One example of chemical communication between individuals dictyostelium discodium. To form fruiting bodies in response to a concentration gradient of a chemical signal released by other dicty.
