Introduction to the Sutures of the Skull: Sutures (L., sutura, from suere ‘to sew’) are junctions (or lines of articulation) between adjacent bones of the skull. The coronal suture is a dense and fibrous association of connection tissue located in between the frontal and parietal bones of the skull. Composition of the Skull The adult human skull is comprised of twenty-two bones which are divided into two parts of differing embryological origin: the neurocranium and the viscerocranium. • One in three infants has some degree of skull distortion. How to use suture in a sentence. The sutures meet at the fontanels, the soft spots on your baby's head. At birth, the sutures decrease in size (molding) and allow the skull to become smaller.

When this occurs, the suture is said to “close.” In a baby with craniosynostosis, one or more of the sutures closes too early. In fact the intricate windy lines of these thin lines mark the adherence between the bones and the growth and closure of the cranial fontanelles.. Some types of sutures are available with specialized coatings on the surface to enhance properties like knotting, easy passage through tissue and reduce tissue reaction. ‘This is a small holopid with rounded whorls, deep sutures and a body whorl bearing coarse collabral threads.’ Skull definition, the bony framework of the head, enclosing the brain and supporting the face; the skeleton of the head. The skull is formed of several bones which, with the exception of the mandible, are joined together by sutures—synarthrodial (immovable) joints. 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.
