Term
postganglionic cell bodies
Definition
the _________ of sympathetic nerves and ganglia are located in a chain of paravertebral ganglia from cervical to sacral levels and preaortic ganglia in abdomen

Term
sympathetic preganglionic motor cell bodies
Definition
these are found only in T1-L2 spinal cord levels
Term
sympathetic preganglionic motor fibers
Definition
these travel in ventral root with somatic motor fibers and eventually into nerve formed by the union of dorsal and ventral roots
