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 cranial cavity, also known as intracranial space, is the space within the skull that accommodates the brain.The skull is also known as the cranium. [1] The cranial cavity is formed by eight cranial bones known as the neurocranium that in humans includes the skull cap and forms the protective case around the brain.
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.
A cranial fossa is formed by the floor of the cranial cavity. There are three distinct cranial fossae: [1] Anterior cranial fossa (fossa cranii anterior), housing the projecting frontal lobes of the brain [2] Middle cranial fossa (fossa cranii media), separated from the posterior fossa by the clivus and the petrous crest housing the temporal ...
The cranial bones are joined at firm fibrous junctions called sutures and contains many foramina, fossae, processes, and sinuses. In zoology, the openings in the skull are called fenestrae, the most prominent of which is the foramen magnum, where the brainstem goes through to join the spinal cord.
The anterior cranial fossa is a depression in the floor of the cranial base which houses the projecting frontal lobes of the brain. It is formed by the orbital plates of the frontal, the cribriform plate of the ethmoid, and the small wings and front part of the body of the sphenoid; it is limited behind by the posterior borders of the small wings of the sphenoid and by the anterior margin of ...
Inner surface of the base of skull, showing cranial foramina. The foramen is situated just anterior to the sphenopetrosal suture. [1]: 509 It is located posterolateral to the foramen ovale, and anterior to the sphenoidal spine. [2] A groove for the middle meningeal artery and vein extends anterolaterally from the foramen.
