Apical foramen, the opening at the tip of the root of a tooth; Foramen ovale (heart), an opening between the venous and arterial sides of the fetal heart; Foramen transversarium, one of a pair of openings in each cervical vertebra, in which the vertebral artery travels; Greater sciatic foramen, a major foramen of the pelvis
In anatomy and osteology, a foramen (/ f ə ˈ r eɪ m ən /; [1] [2] pl.: foramina, / f ə ˈ r æ m ɪ n ə / or foramens / f ə ˈ r eɪ m ən z /; from Latin 'an opening produced by boring') is an opening or enclosed gap within the dense connective tissue (bones and deep fasciae) of extant and extinct amniote animals, typically to allow passage of nerves, arteries, veins or other soft ...
Its outer surface is rough and gives attachment to the occipitalis and posterior auricular muscles.It is perforated by numerous foramina (holes); for example, the mastoid foramen is situated near the posterior border and transmits a vein to the transverse sinus and a small branch of the occipital artery to the dura mater.
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.
The foramen magnum (Latin: large hole) is a large oval foramen longest front to back; it is wider behind than in front where it is encroached upon by the occipital condyles. The clivus, a smooth bony section, travels upwards on the front surface of the foramen, and the median internal occipital crest travels behind it. [3]
The intervertebral foramen (also neural foramen) (often abbreviated as IV foramen or IVF) is an opening between (the intervertebral notches of [1]) two pedicles (one above and one below) of adjacent vertebra in the articulated spine.
A glomus jugulare tumor grows in the temporal bone of the skull, in an area called the jugular foramen. The jugular foramen is also where the jugular vein and several important nerves exit the skull. This area contains nerve fibers, called glomus bodies. Normally, these nerves respond to changes in body temperature or blood pressure.
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
