In the cervical spine, Structure B corresponds to which feature?

• A. Intervertebral foramen
• B. Spinous process
• C. Pedicle
• D. Lamina

Answer: (A)

The structure is the intervertebral foramen—the opening between two adjacent cervical vertebrae through which the exiting spinal nerve travels from the spinal canal to the periphery. It is formed by the notches on the pedicles of the two vertebrae (the inferior notch of the upper vertebra and the superior notch of the lower vertebra). In imaging, especially oblique views of the cervical spine, this foramen appears as a lateral hole beside the vertebral bodies. The other options are features of a single vertebra: the spinous process is the posterior projection, the pedicle is the short connection from the body to the arch, and the lamina forms the posterior portion of the vertebral arch. These are not gaps between vertebrae where nerves exit, so they don’t match Structure B.
