Question

Quizplus · Accepted Answer

Endocrine signaling involves the release of hormones from one cell (endocrine cell) and their transport through the bloodstream to reach other cells in distant organs where they exert their effects. Paracrine signaling occurs when the signaling molecule acts locally on neighboring cells, contact-to-contact signaling involves direct contact between cells, autocrine signaling is when the signaling molecule acts on the same cell that released it, and intercellular signaling is a more general term that encompasses all forms of signaling between cells.
