The coronal suture (sutura coronalis) is a dense, fibrous connective tissue joint that separates the frontal and 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. There are two possible deformities that can be caused by the premature closure of the coronal suture: a high, tower-like skull called "oxycephaly," or a twisted and asymmetrical skull called "plagiocephaly." 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 frontal bone (os frontale) is a bone in the human skull that resembles a cockle-shell in form, and consists of two portions—a vertical portion, the squama, corresponding with the region of the forehead; and an orbital or horizontal portion, which enters into the formation of the roofs... The parietal bones (os parietale) are bones in the human skull and form, by their union, the sides and roof of the cranium. ...
