Which term denotes a round or oval opening through a bone?

• A. Foramen
• B. Fossa
• C. Meatus
• D. Notch

Answer: (A)

A foramen is the correct term. It refers to a round or oval opening that goes through a bone, providing a passage for nerves, blood vessels, or other structures. That opening shape and purpose fit the idea of allowing things to pass from one side of the bone to the other, such as the foramen magnum through which the spinal cord passes. The other features describe different bone surfaces: a fossa is a shallow basin-like depression, a meatus is a canal or tunnel through bone, and a notch is an indentation along the edge of a bone.
