Paracrine signaling involves the secretion of a signal molecule by a cell into the local environment, which then affects nearby cells. This is different from endocrine signaling, which involves the secretion of hormones into the bloodstream to affect distant cells, and synaptic signaling, which involves the transmission of signals between neurons through specialized junctions called synapses. The extracellular matrix is not directly involved in signaling, although it can provide structure and support for cells.
