Ventral primary ramus
Introduction
Overview
Overview
The ventral ramus (anterior ramus, anterior branch, anterior divisions of the spinal nerves) supply the antero-lateral parts of the trunk, and the limbs; they are for the most part larger than the posterior divisions.
In the thoracic region they run independently of one another, but in the cervical, lumbar, and sacral regions they unite near their origins to form plexuses.
The Ventral rami, including the sinuvertebral nerve branches, supply structures anterior to the facet joint, including the vertebral bodies, the discs and their ligaments and joints other spinal nerves to form the lumbo-sacral plexus.
