Foramen

In anatomy and osteology, a foramen (/fəˈrmən/;[1][2] plural foramina, /fəˈræmɪnə/ or foramens /fəˈrmənz/) is an open hole that is present in extant or extinct amniotes. Foramina inside the body of animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another.

Skull

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

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.
