Sympathetic Preganglionic Neurons

Question

Sympathetic preganglionic neurons
A)originate in the brainstem and sacral region of the spinal cord.
B)originate in the cerebrum of the brain.
C)originate in the thoracic and lumbar region of the spinal cord.
D)tend to be relatively long.
E)synapse in the terminal ganglion.

Accepted Answer

Sympathetic preganglionic neurons originate in the thoracic and lumbar region of the spinal cord, known as the thoracolumbar region. This is in contrast to parasympathetic preganglionic neurons, which originate in the brainstem and sacral region of the spinal cord. Sympathetic preganglionic neurons tend to be relatively short, and they synapse in the sympathetic chain ganglia located along the spinal cord.
