Which structure is listed as a content of the intervertebral foramen in the provided material?

• A. Dorsal Root Ganglion
• B. Spinal Artery
• C. Epidural Space
• D. Vertebral Body

Answer: (B)

Intervertebral foramen contents include the spinal nerve as it exits the spinal canal, along with sensory structures like the dorsal root ganglion and accompanying vessels that travel with the nerve. Among the options, the spinal artery represents a vascular structure that accompanies the nerve through the foramen as a radicular/segmental artery to supply the nerve roots and surrounding meninges, which is why it is listed as a content of the foramen. The other options don’t pass through the foramen in the same way: the epidural space lies outside the dura, the vertebral body sits anterior to the foramen, and while the dorsal root ganglion is associated with the nerve, the material in question highlights the vascular content.
