Definition

Noun: 1. A specific craniometric point on the skull: The stephanion is the precise anatomical point on the coronal suture of the human skull that is located directly superior to (above) the external opening of the acoustic meatus (ear canal). It is a landmark used in physical anthropology, forensic science, and medicine for precise measurement and description of skull morphology.

Usage Examples

• Noun:
  • The forensic anthropologist marked the stephanion to take a crucial cranial measurement.
  • In the study, the distance from the nasion to the stephanion was recorded for each specimen.

Advanced Usage

• As a fixed anatomical landmark: The term is used almost exclusively in technical, scientific contexts to refer to this specific, unvarying point. It is not used in everyday language.
  • The research paper detailed the spatial relationship between the stephanion and the pterion.

Variants and Related Words
