WebOne example of paracrine signaling is the transfer of signals across synapses between nerve cells. A nerve cell consists of a cell body, several short, branched extensions called dendrites that receive stimuli, and a long extension called an axon, which transmits signals to other nerve cells or muscle cells. WebFor example, yeast produce chemical signals that allow them to find mates. Some species of bacteria coordinate their actions in order to form large complexes called biofilms, or to organize the production of toxins to kill competing organisms.
