Which term describes a narrow, slitlike opening; cleft or groove?

Explanation:
Think about how openings in bone are described by their shape. A fissure is a narrow, slit‑like opening that allows nerves or vessels to pass through. In contrast, a foramen is a round or oval hole, a groove is a long shallow groove or channel that can guide structures but isn’t a hole, and a notch is an indentation at the edge of a bone. Because the prompt specifies a narrow slit‑like opening, fissure is the best fit. An example is the superior orbital fissure in the skull, a slit‑like passage for nerves and vessels.
