The pterygoid canal, also known as the Vidian canal, is a foramen in the base of skull, located in the sphenoid bone, inferomedial to the foramen rotundum. It transmits the Vidian artery and Vidian nerve from the middle cranial fossa to the pterygopalatine fossa. It is an important structure a...
The sphenoethmoidal suture marks the osseous union between the crest of sphenoid bone and the perpendicular and cribiform plates of ethmoid bone.
The parietotemporal/parietomastoid suture represents the articulation between the parietal and temporal bones posteriorly. Anteriorly, they articulate at the squamosal suture. The parietotemporal suture is considered the most posterior continuation of squamosal suture and is at times interrupted...
The sphenopetrosal suture is the cranial suture connecting the greater wing of sphenoid with the petrous part of the temporal bone in the middle cranial fossa. This fissure is located immediately posterior to the foramen ovale and forms part of the posterior wall of the foramen lacerum.
The occipitotemporal/occipitomastoid suture is the obliquely oriented articulation of the anterior border of the squamous occipital bone and the mastoid portion of the temporal bone. A mastoid foramen is occasionally located near or in it. The occipitotemporal suture and the parietotemporal sut...
