Which forms the superior border of an IVF?

• A. lamina
• B. spinous process
• C. pedicle
• D. uncinate process

Answer: (C)

The opening between two adjacent vertebrae, the intervertebral foramen, is shaped mainly by the pedicles. The borders of this foramen are formed by the notches on the pedicles, with the superior border specifically created by the inferior notch of the pedicle of the vertebra above (and the inferior border by the superior notch of the pedicle of the vertebra below). The lamina and spinous process are part of the posterior elements of the vertebral arch and do not form the foraminal borders, while the uncinate process is a cervical feature that forms uncovertebral joints rather than contributing to the foraminal boundary. So, the structure that forms the border is the pedicle.
