From "Cellular Communication:"

"Billions of years before cell phones, dropped calls and texting while driving biological cells were prodding the cell next to them and asking ‘R U there?’ Cells, particularly in confederations such as human bodies are constantly sending and receiving messages; constantly building and destroying the proteins and enzymes used like words for this communication. And like the phone system calls can be either local or long-distance. Local communication is through paracrine or synaptic signaling. In paracrine communication a cell creates and releases a protein into the interstitial fluid between cells. If this protein matches up with a receptor on an adjacent cell then that cell will ‘accept the call’ and perform an appropriate action. Synaptic signaling is similar but is only used by nerve and brain cells and the proteins are passed across much smaller distances (synaptic gaps) between very specific cells rather than simply being released into the intercellular fluid.
