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 ...
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 otic ganglion is a small parasympathetic ganglion located immediately below the foramen ovale in the infratemporal fossa and on the medial surface of the mandibular nerve. It is functionally associated with the glossopharyngeal nerve and innervates the parotid gland for salivation. It is one of four parasympathetic ganglia of the head and neck.
The temporal fossa is a fossa (shallow depression) on the side of the skull bounded by the temporal lines above, and the zygomatic arch below. Its floor is formed by the outer surfaces of four bones of the skull.
