Sympathetic

Explanation:

Preganglionic motor neurons are a part of the autonomic nervous system - a part of the nervous system that acts mostly involuntarily and regulates bodily functions, such as the heart rate, breathing, digestion, etc.

A preganglionic motor neuron is a type of motor neuron, the cell body of which is located in the brain or spinal cord, while its axon leaves the central nervous system as part of a cranial or spinal nerve before separating and entering the autonomic ganglion.

The preganglionic neurons that originate in the thoracic and lumbar regions of the spinal cord are the sympathetic preganglionic neurons.
