Other articles where Chemical signaling is discussed: cell: Cell-to-cell communication via chemical signaling: In addition to cell-matrix and cell-cell interactions, cell behaviour in multicellular organisms is coordinated by the passage of chemical or electrical signals between cells. Additionally, this signaling is unidirectional. A benefit of electrical synapses is they will transmit signals in both directions. autocrines, paracrines, neurotransmitters, hormones, neurohormones, chemical acts on another cell which is located close to the cell from which it is released, chemical acts on another cell which is locate far away from the cell which it is released, utilised bloodstream as a transport system, chemical acts on same cell from which it is released, often a mechanism for limiting release of the chemical, derived from individual cells, effect on neighbouring cells in immediate environment of their site of secretion, don't enter blood as inactivated by enzymes, Histamine released by mast cell (connective tissue) dilates blood vessels in the vicinity.
