How is synaptic signaling different from paracrine signaling?

Question

Quizplus · Accepted Answer

Synaptic signaling specifically involves neurotransmitters that are released from neurons, while paracrine signaling entails the release of signaling molecules from one cell that act on nearby target cells. Synaptic signaling is highly localized and rapid, while paracrine signaling is more diffuse and slower in comparison. Additionally, synaptic signaling requires receptors on the target cell to elicit a response, while paracrine signaling can utilize both receptor-mediated and non-receptor-mediated mechanisms. Therefore, choice A is the correct answer as it uniquely characterizes synaptic signaling.
