Anatomy
Structure
In the thoracic region and lumbar region, each vertebral foramen is additionally bounded anteriorly by (the inferior portion of) the body of vertebra (particularly in the thoracic region) and adjacent intervertebral disc (particularly in the lumbar region).[2]: 425
In the cervical region, a small part of the body of vertebra inferior to the intervertebral disc also forms the anterior boundary of the IVF (due to the fact that the junction of the pedicle with the body of vertebra is situated somewhat more inferiorly on the body).[2]: 425
Contents
A number of structures pass through the IVF: spinal nerve roots, a recurrent meningeal nerve,[3] radicular arteries (where present),[4][2]: 492–493 segmental medullary arteries (where present),[4] intervertebral veins,[5] and lymphatic vessels.[3]
