Nerves Visceral Sacral

Internal sacral nerves (lat. Nervi splanchnici sacrales) are nerves that are part of the lumbosacral plexus.

The splanchnic sacral nerve (lat. nervus splanchnicus sacralis) is a nerve that is part of the sacral section of the spinal nerves.

They form the lumbocruciate plexus, which is located at the level of the L1-L4 bodies.

The lumbosacral nerve exits the abdominal cavity through the greater sciatic foramen, located on the border between the middle and outer third of the sacrum.

Splanchnic (internal) nerves - formed from the thoracic sympathetic trunk and S1-S4 spinal nerves; go towards the abdominal organs, for which they are called visceral.

The splanchnic nerves are divided depending on the place of exit. Along the line of attachment of nerve cell trunks, 1) true splanchnic nerves are distinguished; 2) cervical visceral; according to the number of branches - 3) one-sided (usually right or left); 4) bilateral; 5) multibranched (more than two branches are formed from one trunk). Sometimes isolated
