Does the spinal cord pass through the intervertebral foramen?

What passes through the intervertebral foramen?

The foramen allows for the passage of the spinal nerve root, dorsal root ganglion, the spinal artery of the segmental artery, communicating veins between the internal and external plexuses, recurrent meningeal (sinu-vertebral) nerves, and transforaminal ligaments.

Does the spinal cord pass through the intervertebral foramina?

The intervertebral foramen

The intervertebral foramina which transmit the spinal nerves and the accompanying radicular arteries (which supply the spinal cord) are on the lateral aspect of the vertebral column.

What spinal nerve passes through this intervertebral foramen?

The transverse cervical nerve, of C2 and C3, projects posteriorly and wraps around anteriorly to supply the skin of the anterior cervical region. The supraclavicular nerve, of C3 and C4, descends from the posterior sternocleidomastoid and provides sensory information from the skin over the clavicle and shoulder. [1][7]
