obelion
Noun: A specific point on the top of the human skull. It is the craniometric point on the sagittal suture (the seam running from the front to the back along the top of the skull) where it is intersected by an imaginary line connecting the two parietal foramina (small holes in the parietal bones). It is located near the lamboid suture (the seam at the back of the skull).
The term 'obelion' is a highly specialized anatomical term used primarily in physical anthropology, osteology, and forensic science to describe a precise location on the cranium for measurement or identification purposes.
- In his research on skull variation, the anthropologist measured the distance from the obelion to the bregma.
- The presence of a metopic suture can affect the precise location of the obelion.
- A key landmark for certain cranial measurements is the obelion.
- Obelionic Region: Refers to the general area around the obelion point on the skull.
- The obelion is one of several standard craniometric points used to calculate cranial indices and study human biological variation.
- Craniometric Point (n): Any of the standard points on the skull used for making precise measurements. The obelion is one such point.
- Sagittal Suture (n): The fibrous joint between the two parietal bones of the skull, on which the obelion is located.
- Bregma (n): The craniometric point where the coronal and sagittal sutures meet, located anterior to the obelion.
- Lambda (n): The craniometric point where the sagittal and lamboid sutures meet, located posterior to the obelion.
- Cranial Landmark: A general term for any identifiable point on the skull used for reference. (Note: This is a broader, less precise synonym.)
This word has a single, very specific meaning within its technical field. It is not used in everyday language and has no idiomatic or phrasal verb applications.
