Question

Quizplus · Accepted Answer

The correct sequence for the sympathetic motor pathway starts with the neuron exiting the lumbar segment of the spinal cord (4), followed by the release of acetylcholine (6), which then binds to the nicotinic receptor (5). This leads to the depolarization of the postganglionic neuron (1), which releases acetylcholine (3), and finally, acetylcholine binds to the sweat gland's muscarinic receptor (2).
