Obelion
Obelion
Obelion (pronounced: /oʊˈbiːliən/) is a term used in anatomy to refer to a specific point on the human skull.
Etymology
The term "Obelion" is derived from the Greek word "obelos" which means "needle". This is due to the obelion point being located at the approximate position where the sagittal suture of the skull, which resembles a needle in shape, reaches its highest point.
Definition
The obelion is a craniometric point in the human skull. It is located on the sagittal suture, which is the line where the two parietal bones of the skull meet. The obelion is specifically situated between the anterior fontanelle and posterior fontanelle, closer to the latter.
