Definition
Noun: A specific type of fibrous joint (suture) in the human skull. It is the serrated, interlocking connection between the occipital bone (at the back and base of the skull) and the two parietal bones (forming the top and sides of the skull). Its name derives from its resemblance to the Greek letter lambda (Λ).
Usage
The term is used exclusively in anatomical, medical, and anthropological contexts to describe this precise cranial feature. - The sutura lamboidea closes and fuses in adulthood, a process known as synostosis. - Anthropologists study the pattern of the sutura lamboidea to help determine the age of skeletal remains.
Advanced Usage
- Lambdoid Suture: This is the more common English synonym. The phrase "sutura lamboidea" is the formal Latin-derived term used in technical nomenclature.
