Question

Which of the following is true about postganglionic axons of autonomic neurons?
A) They are unmyelinated.
B) They are myelinated.
C) They are located in the spinal cord.
D) They are located in the brain.

Postganglionic axons of autonomic neurons are typically unmyelinated, which contrasts with the often myelinated preganglionic axons. This characteristic contributes to the different conduction speeds between these two types of fibers.
