Intervertebral foramen, foramina formed between vertebrae; Lesser sciatic foramen, an opening between the pelvis and the posterior thigh; Obturator foramen, the opening created by the ischium and pubis bones of the pelvis; Vertebral foramen, the foramen formed by the anterior segment (the body), and the posterior part, the vertebral arch
Sacral foramina, which perforate the vertebral canal from the Sacrum (sacral bone), and through which the sacral nerves pass. Vertebral foramen, the foramen formed by the anterior segment (the body), and the posterior part, the vertebral arch. Foramen of Panizza, a hole connecting two aortas just after they leave the heart in crocodiles.
In a typical vertebra, the vertebral foramen is the foramen (opening) of a vertebra bounded ventrally/anteriorly by the body of the vertebra, and the dorsally/posteriorly by the vertebral arch. [ 1 ] : 421
These foramina are the entry and exit conduits for the spinal nerves. The body of the vertebra and the vertebral arch form the vertebral foramen, the larger, central opening that accommodates the spinal canal, which encloses and protects the spinal cord.
In the cervical region, a small part of the body of vertebra inferior to the intervertebral disc also forms the anterior boundary of the IVF (due to the fact that the junction of the pedicle with the body of vertebra is situated somewhat more inferiorly on the body). [2]: 425
A foramen is any opening, particularly referring to those in bone. [14] 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. An example is the foramen magnum in occipital bone.

It arises from the side of the body, is directed laterally in front of the foramen, and ends in a tubercle, the anterior tubercle. The posterior part, the true transverse process, springs from the vertebral arch behind the foramen and is directed forward and laterally; it ends in a flattened vertical tubercle, the posterior tubercle.
