Which is also a bony border of the IVF?

• A. Vertebral Notches
• B. Pedicles
• C. Laminae
• D. Spinous processes

Answer: (A)

The opening through which a spinal nerve exits (the intervertebral foramen) gets its top and bottom margins from the vertebral notches. Each vertebra has a superior and an inferior vertebral notch along its pedicle. When two vertebrae sit one above the other, the inferior notch of the upper vertebra lines up with the superior notch of the lower vertebra to form the superior and inferior borders of the foramen. The foramen’s front is the adjacent vertebral bodies and intervertebral disc, while the back is formed by the facet joints and related ligaments. So the vertebral notches are the specific bony borders in question.
