Nerve Ganglion

Saturday, August 2, 2014

A nerve ganglion is a group of neurons (nerve cells) that constitute a nerve center, which sends out and receives nerve fibers connecting to other nerves or ganglia. It is located outside the brain and the spinal cord, that is to say, outside the central nervous system. Ganglia are part of the peripheral nervous system. There is a chain of ganglia lying along both sides of the spinal column, being interconnected with the spinal cord nerve roots; they form what is called the sympathetic trunk.
