Which combination lists the border components of the spinal canal as listed?

• A. Body/Corpus; Pedicles (2); Laminae
• B. Body/Corpus; Pedicles
• C. Laminae
• D. Pedicles (2)

Answer: (A)

The border of the spinal canal is formed by three main regional elements: the vertebral body forms the anterior wall, the pedicles on either side form the lateral walls, and the laminae form the posterior wall. Including all three components—body, pedicles (two), and laminae—accurately lists the boundaries of the canal. The other options miss one of these essential elements, making them incomplete descriptions of the border.
