Question

Quizplus · Accepted Answer

Paracrine agents are signaling molecules released by cells that affect other cell types in close proximity to the releasing cell. Pheromones are released into the environment to affect the behavior of other organisms, while hormones are released into the bloodstream to have systemic effects on the body. Neurotransmitters are released by neurons to affect neighboring cells in the nervous system. Autocrine agents are self-signaling molecules that bind to receptors on the same cell that released them.
