What is temporal and infratemporal fossa?
The infratemporal fossa is an irregular space at the lateral aspect of the skull. As its name suggests, it is situated just inferior to the temporal fossa and deep to the ramus of the mandible. The temporal and infratemporal fossae communicate with each other through the opening deep to the zygomatic arch.
What do the temporal fossa and infratemporal fossa contain?
The infratemporal fossa contains the mandibular nerve, the inferior alveolar nerve, the lingual nerve, the buccal nerve, the chorda tympani nerve, and the otic ganglion.
What is the significance of the infratemporal fossa?
Nerves coursing through and around the infratemporal fossa are responsible for providing a vast majority of sensory and motor function to the lower face and other important structures such as the dura mater.
What structure marks the boundary between the temporal and infratemporal fossa?
Bony framework Bones that contribute significantly to the boundaries of the temporal and infratemporal fossae include the temporal, zygomatic, and sphenoid bones, and the maxilla and mandible.
What is temporal fossa?
The temporal fossa is the area on the side of the cranium from which the temporal muscle arises. The skin over this area is relatively thin and derives its blood supply from branches of the superficial temporal artery. It is drained chiefly by the superficial temporal vein.
Where is the temporal fossa located?
cranium
The temporal fossa is the area on the side of the cranium from which the temporal muscle arises. The skin over this area is relatively thin and derives its blood supply from branches of the superficial temporal artery. It is drained chiefly by the superficial temporal vein.
What is the infratemporal surface of the maxilla?
The infratemporal surface is convex, directed backward and lateralward, and forms part of the infratemporal fossa. It is separated from the anterior surface by the zygomatic process and by a strong ridge, extending upward from the socket of the first molar tooth.
What is the temporal fossa?
Which of the following structures is located or travels within the infratemporal fossa?
The infratemporal fossa contains several vascular structures: Maxillary artery – the terminal branch of the external carotid artery. It travels through the infratemporal fossa. Within the fossa, it gives rise to the middle meningeal artery, which passes through the superior border via the foramen spinosum.
Where is the temporal fossa found?
What is infratemporal surface?
What does temporal fossa mean?
The space on the side of the cranium bounded by the temporal lines and terminating below at the level of the zygomatic arch.
What bone is the temporal fossa on?
The bony part of the temporal fossa is formed anteriorly by the zygomatic bone, somewhat more posteriorly by the greater wing of the sphenoid, and still farther posteriorly by the temporal squama. But the upper margin of the temporal muscle is applied to the squama of the frontal bone and to the parietal bone.
What structure lies in the temporal fossa?
The temporal fossa contains several nervous branches that include: The deep temporal nerves (of mandibular nerve) The zygomaticotemporal nerve (of maxillary nerve) The auriculotemporal nerve (of maxillary nerve)
