Ganglion Sympathetic Paravertebral

Paravertebral sympathetic ganglion (g. trunci sympathici, pna, bna, jna; synonym for sympathetic trunk) is a collection of nerve cells located along the sympathetic trunk on both sides of the spine. It is part of the sympathetic nervous system.

The ganglion includes the bodies of neurons, the processes of which innervate internal organs, blood and lymphatic vessels. The ganglion regulates their activity, participating in maintaining homeostasis of the body. It is closely related to the parasympathetic nervous system and together with it forms the autonomic nervous system.

The ganglion has a fusiform shape and consists of several sections in the cervical, thoracic, lumbar and sacral spine. The size and number of neurons in it depends on the level of location. The ganglion plays an important role in regulating the vital functions of the body.

The paraverteral sympathetic ganglion is a small cavity located next to the spine. It serves as a passageway for nerve fibers that transmit signals from the brain and spinal cord to various organs and tissues.
