The middle meningeal artery is the largest of the three (paired) arteries that supply the meninges, the others being the anterior meningeal artery and the posterior meningeal artery. The anterior branch of the middle meningeal artery runs beneath the pterion. It is vulnerable to injury at this point, where the skull is thin. Rupture of the ...
Reid's base line is used as the zero plane in computed tomography. Paediatric base line is an anatomic line that maintains a fixed relation to facial bones throughout the period of growth. In 1962, the World Federation of Radiology defined it as the line between the infraorbital margin and the upper margin of the external auditory meatus.
middle meningeal artery: meningeal branch of the mandibular nerve (V 3) sphenoid: middle cranial fossa: foramen lacerum: 2: artery of pterygoid canal, Meningeal branch of ascending pharyngeal artery, emissary vein: nerve of pterygoid canal through its anterior wall temporal: middle cranial fossa: carotid canal: 2: internal carotid artery
The middle region is a mostly fibrous portion. It consists of two layers: the endosteal layer, which lies closest to the skull, and the inner meningeal layer, which lies closer to the brain. [7] It contains larger blood vessels that split into the capillaries in the pia mater. It is composed of dense fibrous tissue, and its inner surface is ...
The middle cranial fossa is formed by the sphenoid bones, and the temporal bones. It lodges the temporal lobes, and the pituitary gland. [1] [2] It is deeper than the anterior cranial fossa, is narrow medially and widens laterally to the sides of the skull. It is separated from the posterior cranial fossa by the clivus and the petrous crest.
The infratemporal fossa contains the maxillary artery (originating from the external carotid artery). [1] It also contains some of its branches, including the: middle meningeal artery; inferior alveolar artery; deep temporal artery; buccal artery
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.

The base of skull, also known as the cranial base or the cranial floor, is the most inferior area of the skull. It is composed of the endocranium and the lower parts of the calvaria . Structure
