The sagittal suture, also known as the interparietal suture and the sutura interparietalis, [citation needed] is a dense, fibrous connective tissue joint between the two parietal bones of the skull. The term is derived from the Latin word sagitta , meaning arrow .
Unless rarely, fracture involves the suture lines (more common in children), then epidural hematoma may cross the suture lines. [4] As the blood accumulated in the epidural space is confined within suture lines, accumulation of additional blood will cause bulging in this space, and thus resulting in a typical "biconvex" appearance on CT scans.

Side view of the skull Human skull side sutures right. A suture is a type of fibrous joint that is only found in the skull (cranial suture). The bones are bound together by Sharpey's fibres. A tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull. These joints are synarthroses. [1]
The swelling may obscure the fontanel and cross cranial suture lines, distinguishing it from cephalohematoma, [2] in which the bleed is confined by its subperiosteal location. [3] Patients with subgaleal hemorrhage may also have significant hyperbilirubinemia due to resorption of hemolyzed blood. Laboratory studies may demonstrate reduced ...
Wormian bones, also known as intrasutural bones or sutural bones, [1] are extra bone pieces that can occur within a suture (joint) in the skull.These are irregular isolated bones that can appear in addition to the usual centres of ossification of the skull and, although unusual, are not rare. [2]
It forms the main component of the skull roof. The calvaria is made up of the superior portions of the frontal bone, occipital bone, and parietal bones. [1] In the human skull, the sutures between the bones normally remain flexible during the first few years of postnatal development, and fontanelles are palpable.
Metopism is the condition of having a persistent metopic suture, [2] or persistence of the frontal metopic suture in the adult human skull. [3] Metopism is the opposite of craniosynostosis. [4] The main factor of the metopic suture is to increase the volume of the anterior cranial fossa.
