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; Interventricular foramen, channels connecting ventricles in the brain
The foramen of Magendie is named for François Magendie, who first described it. [6] The term "foramen of Magendie" is commonly used, and this opening is frequently described and illustrated as a foramen in the inferior roof of the fourth ventricle. However, the opening is an aperture, rather than a foramen. [5] CSF circulation
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 ...
Cross section of the gut. The lumen is the space in the middle also known as the volume. Normal histology of the breast, with lumen annotated at bottom right [1] In biology, a lumen (pl.: lumina) is the inside space of a tubular structure, such as an artery or intestine. [2]
The interventricular foramina are two holes (Latin: foramen, pl. foramina) that connect the left and the right lateral ventricles to the third ventricle. [1]They are located on the underside near the midline of the lateral ventricles, [2] and join the third ventricle where its roof meets its anterior surface. [3]
It is most distinct above and at the sides of the fossa ovalis; below, it is deficient. A small slit-like valvular opening is occasionally found, at the upper margin of the fossa, leading upward beneath the limbus, into the left atrium; it is the remains of the fetal aperture the foramen ovale between the two atria.
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.
The superior surface of the sphenoid bone is bounded behind by a ridge, which forms the anterior border of a narrow, transverse groove, the chiasmatic groove (optic groove), above and behind which lies the optic chiasma; the groove ends on either side in the optic foramen, which transmits the optic nerve and ophthalmic artery (with accompanying ...
