The
sagittal suture 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. The derivation of this term may be demonstrated by observing how the sagittal suture is notched posteriorly, like an arrow, by the
lambdoid suture. The sagittal suture is also known as the
interparietal suture and the
sutura interparietalis.
