E) Synaptic

Question

Quizplus · Accepted Answer

Juxtacrine signaling is a type of cell-cell communication that requires the cells to be in direct contact with each other. This can occur through the interaction of membrane-bound molecules or by gap junctions that allow for the transfer of molecules between cells. Autocrine signaling occurs when cells respond to signals they produce themselves, while endocrine signaling involves the transmission of signals through the bloodstream to distant cells. Paracrine signaling involves the secretion of signaling molecules that act on nearby cells, and synaptic signaling occurs between neurons at specialized junctions called synapses.
