Encyclopedia > Sagittal suture

The sagittal suture (sutura sagittalis) is a dense, fibrous connective tissue joint between the two parietal bones of the skull. At birth, the bones of the skull do not meet. If certain bones of the skull grow too fast then "premature closure" of the sutures may occur. This can result is skull deformities. If the sagittal suture closes early the skull becomes long, narrow, and wedge-shaped, a condition called "scaphocephaly." Connective tissue is any type of biological tissue with an extensive extracellular matrix and often serves to support, bind together, and protect organs. ... This article is about a joint in zootomical anatomy. ... The parietal bones (os parietale) are bones in the human skull and form, by their union, the sides and roof of the cranium. ... A Hippopotamuss skull A skull, or cranium, is a bony structure of Craniates which serves as the general framework for a head. ... Cephalic disorders are congenital conditions that stem from damage to, or abnormal development of, the budding nervous system. ...


Two anatomical landmarks are found on the sagittal suture: the bregma and the vertex of the skull. The bregma is formed by the intersection of the sagittal and coronal sutures, and the vertex is the highest point on the skull and is many times near the midpoint of the sagittal suture.


The sagittal suture is also known as the "interparietal suture" and the "sutura interparietalis."

Scaphocephaly - Skull Base Institute (384 words)
Scaphocephaly, is the premature closure of the sagittal suture.
The sagittal suture is the long suture on the top of the head that runs from front to back starting at the anterior fontanelle and extending backwards along the middle of the skull to the back of the head.
The head typically is elongated in the anterior-posterior diameter and shortened in the biparietal diameter and the ridging of the sagittal suture is palpable.
