Obelion

Obelion is an anatomical landmark located on the human skull. It is situated on the sagittal suture, which is the fibrous connective tissue joint between the two parietal bones of the skull. The obelion is specifically found between the parietal foramina, which are small openings in the parietal bones that allow the passage of emissary veins.

Anatomy

The obelion is an important point of reference in craniometry, the measurement of the cranium (the part of the skull that encloses the brain). It is used to assess the shape and size of the skull, which can be significant in various fields such as anthropology, forensic science, and medicine.

Location

The obelion is located on the sagittal suture, which runs along the midline of the skull, extending from the front to the back. It is positioned between the parietal foramina, which are typically found near the posterior part of the parietal bones.

Clinical Significance

In clinical practice, the obelion can be used as a reference point during certain surgical procedures involving the skull. Its precise location can help surgeons navigate and avoid critical areas, reducing the risk of complications.
