Question

in the sympathetic division, varicosities that release neurotransmitter near target cells are characteristic of which of the following?

Explanation:

• Somatic motor neurons form neuromuscular junctions, not varicosities near target cells.
• Preganglionic fibers in the sympathetic division do not have varicosities releasing neurotransmitter near target cells in this characteristic way.
• Neuroeffector junctions in the sympathetic division have varicosities that release neurotransmitter near target cells.

Answer:

Neuroeffector junctions
