"If the foramen is not open," Costa stresses, "there is no flow of spirit to the posterior part of the brain and the person does not remember and will not respond to the questions he is asked.
The first is a structure called the foramen ovale.
Nerves exit the spine through a small space called a foramen.
What we do know for certain is that walking bipedally coincided with a change in where our spinal column enters the skull through a "big hole" called the foramen magnum.
It travels through an opening, or foramen, that is close to the jawbone and serves many of the organs of the upper chest, including the heart, stomach, and esophagus.
Near the middle of this surface is the nutrient foramen, which is directed downward.
The Anterior Median Fissure (fissura mediana anterior; ventral or ventromedian fissure) contains a fold of pia mater, and extends along the entire length of the medulla oblongata: it ends at the lower border of the pons in a small triangular expansion, termed the foramen cecum.
The curved, expanded plate behind the foramen magnum is named the squama; the thick, somewhat quadrilateral piece in front of the foramen is called the basilar part, whilst on either side of the foramen is the lateral portion.
At the junction of the upper and middle thirds of the volar surface is the nutrient foramen, which is directed obliquely upward.
Above the foramen is the margin of the orbit, which affords attachment to part of the Quadratus labii superioris.
