WebPreganglionic nerve fibers. In the autonomic nervous system, fibers from the CNS to the ganglion are known as preganglionic fibers. All preganglionic fibers, whether they are in the sympathetic division or in … WebThe sympathetic preganglionic neurons (SPNs) lie within the spinal cord and their axons traverse the ventral horn to exit in ventral roots where they form synapses onto postganglionic neurons. Thus, these neurons are the last point at which the central nervous system can exert an effect to enable changes in sympathetic outflow. This review ... WebApr 11, 2024 · The second (preganglionic) neuron originates from the ciliospinal center and goes to the superior cervical ganglion in the neck. It exits the spinal cord through the dorsal spinal root and enters the paravertebral sympathetic chain.
