Question

question
which of the following does not describe the sympathetic division of the ans?
answer
most postganglionic fibers release ach at neuroeffector junctions.
it is also referred to as the thoracolumbar division of the ans.
preganglionic fibers release ach, stimulating ganglionic neurons.
preganglionic neurons are located in lateral gray horns of spinal cord segments t₁ - l₂.
i dont know yet

Explanation:

• In the sympathetic division of the ANS, most postganglionic fibers release norepinephrine (NE) at neuroeffector junctions, not acetylcholine (ACh).
• The sympathetic division is also called the thoracolumbar division as preganglionic neurons are located in lateral gray horns of spinal cord segments \(T_1 - L_2\).
• Preganglionic fibers in the sympathetic division do release ACh which stimulates ganglionic neurons.

Answer:

Most postganglionic fibers release ACh at neuroeffector junctions.
