Foramen

Summary

In anatomy, a foramen (/fəˈrmən/;[1][2] plural foramina, /fəˈræmɪnə/ or foramens /fəˈrmənz/) is any opening. Foramina inside the body of humans and other animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another.

Skull

The skulls of vertebrates (including humans) have foramina through which nerves, arteries, veins and other structures pass. For example, a human skull has parietal foramen.

Spine

Within the vertebral column (spine) of vertebrates, including the human spine, each bone has an opening at both its top and bottom to allow nerves, arteries, veins, etc. to pass through.
