Cell-to-cell communication through secretion of chemical signals into the bloodstream to target cells throughout the body is called _____ signaling.
A) synaptic
B) paracrine
C) endocrine
D) autocrine

Question

Quizplus · Accepted Answer

Endocrine signaling is accomplished by specialized endocrine cells that secrete hormones that travel via the bloodstream to target cells throughout the body.Synaptic signaling occurs at specialized junctions between the nerve cell and its target cell; the neuron secretes a chemical neurotransmitter into a small space between the nerve and target cell.In paracrine signaling,chemicals are secreted into a localized area,and only those cells in the immediate area are affected.Autocrine signaling occurs when cells respond to signaling molecules that they secrete and provides feedback to that cell rather than other cells.
