The infratemporal fossa is connected to other spaces in the skull. 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.
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 ...
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 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.
The pterygomaxillary fissure is a fissure of the human skull.It is vertical, and descends at right angles from the medial end of the inferior orbital fissure.It is a triangular interval, formed by the divergence of the maxilla from the pterygoid process of the sphenoid.
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 infratemporal fenestra, also called the lateral temporal fenestra or lower temporal fenestra, is the lower of the two and is exposed primarily in lateral (side) view. Temporal fenestrae in relation to the other skull openings in the dinosaur Massospondylus , a type of diapsid .
Chorda tympani then exits the skull by descending through the petrotympanic fissure into the infratemporal fossa. Here it joins the lingual nerve, a branch of the mandibular nerve (CN V 3). Traveling with the lingual nerve, the fibers of chorda tympani enter the sublingual space to reach the anterior 2/3 of the tongue and submandibular ganglion ...
The posterior part of the mandibular fossa, formed by the tympanic part of the bone, is non-articular, and sometimes lodges a portion of the parotid gland. The petrotympanic fissure leads into the middle ear or tympanic cavity ; it lodges the anterior process of the malleus , and transmits the tympanic branch of the internal maxillary artery .
