Squamosal Suture

The Squamosal Suture (pronunciation: skwəˈmōsəl sūCHər) is a cranial suture that connects the temporal bone and the parietal bone in the human skull.

Etymology

The term "Squamosal Suture" is derived from the Latin word "squama" meaning "scale", and the Latin word "sutura" meaning "seam". This is in reference to the scale-like appearance of the suture and its function as a seam between the temporal and parietal bones.

Anatomy

The Squamosal Suture is located on the side of the skull, running in an anteroposterior direction. It is a type of fibrous joint, specifically a synarthrosis, which allows for very little movement. The suture is formed by the overlapping of the squamous part of the temporal bone and the lower border of the parietal bone.
