Avisceral motor neuron whose cell body is within the cns is called a( neuron. a visceral motor neuron whose cell body is within the cns is called a( neuron. upper motor preganglionic somatomotor lower motor postganglionic

I believe the answer is preganglionic neuron. Preganglionic neurons originates in the brainstem or the spinal cord. It is part of the autonomic nervous system. The preganglionic fibers affect the heart, lungs, and abdominal organs with exception of the distal portion of the colon. The cell body of preganglionic neuron is in the brain or spinal cord (CNS), its axon exits the CNS as part of a cranial or spinal nerve. It convey nerve impulses from the CNS to autonomic ganglia.
