Question

multiple choice question
which of the following describes an autonomic preganglionic neuron?
it has its cell body in the spinal cord or the brainstem and its axon terminates in a ganglion.
it is myelinated and extends from the cns to the target cell.
it is unmyelinated and extends from the autonomic ganglion to the target cell.
need help? review these concept resources.

Explanation:

Autonomic preganglionic neurons have their cell bodies in the central nervous system (CNS - spinal cord or brainstem). Their axons (which are myelinated) terminate in autonomic ganglia. The second option is wrong as pre - ganglionic neurons do not extend to the target cell (post - ganglionic neurons do). The third option describes post - ganglionic neurons (unmyelinated and from ganglion to target cell).

Answer:

It has its cell body in the spinal cord or the brainstem and its axon terminates in a ganglion.
