The<unk><unk>  (anterior<unk> , anterior branch, anterior divisions of the spinal<unk> s) 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<unk>  rami, including the sinuvertebral<unk>  branches, supply structures anterior to the facet joint, including the vertebral bodies, the discs and their ligaments and joints other spinal<unk> s to form the lumbo-sacral plexus.
