Quizplus · Accepted Answer

Hormones in the bloodstream act similarly to neurotransmitters in the synapse in that they both bind to specific receptors on target cells to produce a response. Just like how neurotransmitters bind to receptors on the postsynaptic cell to either excite or inhibit its response, hormones bind to receptors on target organs or tissues to induce a physiological response.
