The Sympathetic Nerves
Henry Gray
(1825–1861). Anatomy of the Human Body.
1918.
The sympathetic nervous
system innervates all the smooth muscles and the various glands of the body,
and the striated muscle of the heart. The efferent sympathetic fibers which
leave the central nervous system in connection with certain of the cranial and
spinal nerves all end in sympathetic ganglia and are known as preganglionic
fibers. From these ganglia postganglionic fibers arise and conduct impulses
to the different organs. In addition, afferent or sensory fibers connect many of
these structures with the central nervous system.

and its connections with the thoracic, abdominal, and pelvic plexuses. (After

The Nervous System - Groups of Nerves
Your nervous system is composed
of the central nervous system, the cranial nerves, and the peripheral nerves.
The brain and spinal cord together form the central nervous system. The cranial
nerves connect the brain to the head. The four groups of nerves that branch from
the cervical, thoracic, lumbar, and sacral regions of the spinal cord are called
the peripheral nerves. Anatomy
