The foramen spinosum is a small open hole in the greater wing of the sphenoid bone that gives passage to the middle meningeal artery and vein, and the meningeal branch of the mandibular nerve (sometimes it passes through the foramen ovale instead).
Apical foramen, the opening at the tip of the root of a tooth; Foramen ovale (heart), an opening between the venous and arterial sides of the fetal heart; Foramen transversarium, one of a pair of openings in each cervical vertebra, in which the vertebral artery travels; Greater sciatic foramen, a major foramen of the pelvis
The meningeal branch of the mandibular nerve (also known as the nervus spinosus) [1] is a sensory branch of the mandibular nerve (CN V3) that enters the middle cranial fossa through either the foramen spinosum or foramen ovale to innervate the meninges of this fossa as well as the mastoid air cells. [2]
After branching off the maxillary artery in the infratemporal fossa, it runs through the foramen spinosum to supply the dura mater (the outer meningeal layer) and the calvaria. 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 ...
It is connected to the middle cranial fossa by the foramen ovale and the foramen spinosum. It is connected to the temporal fossa, which lies deep to zygomatic arch. It is connected to the pterygopalatine fossa through the pterygomaxillary fissure. It is connected to the orbit through the inferior orbital fissure.

The foramen rotundum is a circular hole in the sphenoid bone of the skull. It connects the middle cranial fossa and the pterygopalatine fossa . It allows for the passage of the maxillary nerve (V 2 ), a branch of the trigeminal nerve .
Foramen ovale. The foramen ovale is an opening in the greater wing of the sphenoid bone. [1] 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.
