Cell Signaling and Receptors
... To function in a biological system, cells communicate with others cells and respond to the external environment. The language of cells is in the form of chemicals = signals There are two general types of signal transmission: 1. Intercellular (inside the cell) 2. Intracellular (between cells) Cel ...
