Autonomic motor neurons leaving the spinal cord synapse once prior to synapsing on the target organ.

Question

Quizplus · Accepted Answer

Autonomic motor neurons generally have two synapses before reaching their target organ - one in the autonomic ganglia and one at the target organ. However, some exceptions exist, such as in the adrenal medulla where the sympathetic preganglionic fibers directly synapse on chromaffin cells, which release adrenaline directly into the bloodstream.
