75308. Anatomical terminology. [edit on Wikidata] The infratemporal fossa is an irregularly shaped cavity that is a part of the skull. It is situated below and medial to the zygomatic arch. It is not fully enclosed by bone in all directions. It contains superficial muscles, including the lower part of the temporalis muscle, the lateral ...
Infratemporal space. Lateral view of skull, with part of the zygomatic complex removed. The infratemporal space is inferior to the base of skull and lateral to the lateral pterygoid plate. The infratemporal space (also termed the infra-temporal space or the infra-temporal portion of the deep temporal space) [1] is a fascial space of the head ...
The deep temporal space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the side of the head, and is paired on either side. It is located deep to the temporalis muscle. The inferior portion of the deep temporal space is also termed the infratemporal space.
In the human skull, the zygomatic bone (from Ancient Greek: ζῠγόν, romanized: zugón, lit. 'yoke'), also called cheekbone or malar bone, is a paired irregular bone, situated at the upper and lateral part of the face and forming part of the lateral wall and floor of the orbit, of the temporal fossa and the infratemporal fossa.
The lateral surface of the greater wing of the sphenoid is convex, and divided by a transverse ridge, the infratemporal crest, into two portions.. The superior or temporal portion, convex from above downward, concave from before backward, forms a part of the temporal fossa, and gives attachment to the Temporalis; the inferior or infratemporal, smaller in size and concave, enters into the ...
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 ...
Temporal fenestrae are commonly (although not universally) seen in the fossilized skulls of dinosaurs and other sauropsids (the total group of reptiles, including birds). [1] The major reptile group Diapsida, for example, is defined by the presence of two temporal fenestrae on each side of the skull. The infratemporal fenestra, also called the ...
Sphenoid bone. Upper surface. (Spina angularis labeled at bottom left.) Articulation of the mandible. Medial aspect. (Spine of sphenoid labeled at center top.) The sphenoidal spine (Latin: " spina angularis ") is a downwardly directed process at the apex of the great wings of the sphenoid bone that serves as the origin of the sphenomandibular ...
