Question

question
which of the following accurately describes preganglionic neurons of the
sympathetic division of the ans?
answer
their cell bodies occupy the lateral portion of anterior
gray horns of spinal segments t₁ - l₂.
their myelinated fibers are carried together as the white
ramus communicans into a nearby collateral ganglion.
none of the listed responses is correct.
their axons enter the ventral roots of spinal segments t₁ -
l₂.
i dont know yet

Explanation:

• Preganglionic neurons of the sympathetic division of the ANS have their cell bodies in the lateral gray horns (not anterior) of spinal segments \(T_1 - L_2\), so the first option is incorrect.
• Their myelinated fibers are carried as white rami communicans to paravertebral (not collateral) ganglia, so the second option is wrong.
• Their axons do enter the ventral roots of spinal segments \(T_1 - L_2\), so the fourth option is correct.

Answer:

Their axons enter the ventral roots of spinal segments \(T_1 - L_2\).
