The foramina in the base of the skull are exit and entry points for veins, arteries and cranial nerves. The cranial nerves as they exit through various foramina. Sphenoidal lingula; Subarcuate fossa; Dorsum sellae; Jugular process; Petro-occipital fissure; Condylar canal; Jugular tubercle; Tuberculum sellae; Carotid groove; Fossa hypophyseos ...
The foramen ovale is one of two cranial foramina in the greater wing, the other being the foramen spinosum. [2]: 771 The foramen ovale is posterolateral to the foramen rotundum and anteromedial to the foramen spinosum. Posterior and medial to the foramen is the opening for the carotid canal. [2]: 776
A jugular foramen is one of the two (left and right) large foramina (openings) in the base of the skull, located behind the carotid canal. It is formed by the temporal bone and the occipital bone. It allows many structures to pass, including the inferior petrosal sinus, three cranial nerves, the sigmoid sinus, and meningeal arteries.
The human skull is the bone structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain. Like the skulls of other vertebrates, it protects the brain from injury. [6] The skull consists of three parts, of different embryological origin—the neurocranium, the sutures, and the ...
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 posterior cranial fossa is the part of the cranial cavity located between the foramen magnum, and tentorium cerebelli. It is formed by the sphenoid bones, temporal bones, and occipital bone. It lodges the cerebellum, and parts of the brainstem.
