In anatomy, the middle temporal artery is a major artery which arises immediately above the zygomatic arch, and, perforating the temporal fascia, gives branches to the temporalis, anastomosing with the deep temporal branches of the internal maxillary.
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 ...
Its outer surface is smooth and convex; it affords attachment to the temporal muscle, and forms part of the temporal fossa; on its hinder part is a vertical groove for the middle temporal artery. A curved line, the temporal line, or supramastoid crest, runs backward and upward across its posterior part; it serves for the attachment of the ...
The foramen spinosum varies in size and location. The foramen is rarely absent, usually unilaterally, in which case the middle meningeal artery enters the cranial cavity through the foramen ovale. [3] It may be incomplete, which may occur in almost half of the population.
In the temporal bone, between the posterior wall of the external acoustic meatus and the posterior root of the zygomatic process is the area called the suprameatal triangle, suprameatal pit, mastoid fossa, foveola suprameatica, or Macewen's triangle, through which an instrument may be pushed into the mastoid antrum.

The inner surface of the mastoid portion presents a deep, curved groove, the sigmoid sulcus, which lodges part of the transverse sinus; in it may be seen in the opening of the mastoid foramen. The groove for the transverse sinus is separated from the innermost of the mastoid cells by a very thin lamina of bone, and even this may be partly ...
The deep temporal arteries anastomose with the middle temporal artery. The anterior artery communicates with the lacrimal artery [1] by means of small branches which perforate the zygomatic bone and greater wing of the sphenoid bone. It may also communicate with the ophthalmic artery, a branch of the internal carotid artery. [1]
