SUTURA INTERPARIETALIS Meaning and
Definition
-
Sutura interparietalis refers to a specific type of cranial suture found in the human skull. It is commonly known as the internasal suture or the interparietal suture and is located in the midline of the cranium, between the parietal bones. The suture is formed by the union of the two parietal bones along the sagittal plane.
The internasal suture can vary in appearance from person to person. In some individuals, this suture is completely fused and cannot be distinguished, while in others, it may present as a visible ridge or line on the midline of the skull. The suture usually begins to fuse and become less visible during early adulthood.
During fetal development, the internasal suture serves a crucial role in facilitating the growth and ossification of the skull. It allows for the expansion of the cranium to accommodate the developing brain. However, once the skull has reached its mature size, the suture starts to close and eventually turns into a bony fusion.
The sutura interparietalis is of importance in the field of anatomy, particularly in the study of human skull morphology. It is used as a reference point for various anatomical measurements and assessments, as well as in determining age estimation in forensic and anthropological contexts.

Etymology of SUTURA INTERPARIETALIS
The word "sutura interparietalis" has Latin origins. "Sutura" means "suture" in Latin, referring to the stitching or joining of two bones together. "Interparietalis" is derived from the Latin words "inter", meaning "between", and "parietalis", meaning "parietal".
In anatomy, the "sutura interparietalis" specifically refers to the suture that joins the two parietal bones of the skull at the midline. This suture is commonly present in infants and is eventually replaced by the "sutura sagittalis" as the skull bones develop during growth.
