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
The foramen magnum varies in size between individuals. Earlier ossification of the occipital bone leads to a smaller foramen. [5] The foramen magnum varies in size and shape when comparing different populations to each other. In humans, men tend to have a larger sized foramen magnum than women, but the overall shape is consistent. [6]
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 ...
The largest of these is the foramen magnum, ... The facial skeleton is one seventh of the size of the calvaria. (In the adult it is half the size).
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 obturator foramen is the large, [citation needed] bilaterally paired opening of the bony pelvis. It is formed by the pubis and ischium . It is mostly closed by the obturator membrane except for a small opening, the obturator canal , through which the obturator nerve and vessels pass.
Those burned turned out to be part of the largest ever T-Rex skeleton to ever be discovered, a 65. On August 12, 1990, Susan Hendrickson -- a fossil hunter -- discovered three huge bones ...
In a typical vertebra, the vertebral foramen is the foramen (opening) of a vertebra bounded ventrally/anteriorly by the body of the vertebra, ...
