brachycranic
Definition
Adjective: * Having a relatively short and broad skull shape, specifically characterized by a cephalic index (the ratio of the maximum width of the head to its maximum length multiplied by 100) of over 80.
Usage
The term is a technical adjective used primarily in physical anthropology, anatomy, and forensic science to describe and classify human skull morphology. It is a precise, scientific descriptor.
Examples
- The anthropologist noted that the ancient skull was brachycranic, indicating a population distinct from the neighboring dolichocranic group.
- Brachycranic individuals have a cephalic index that falls into the broad-headed category.
- The study compared brachycranic and dolichocranic cranial features across different geographic regions.
Advanced Usage
- The term is often used in contrast with its opposites: dolichocranic (long-headed, with a cephalic index under 75) and mesocranic (medium-headed, with a cephalic index between 75 and 80).
- It is typically applied to populations or specific skulls, not as a casual descriptor for living individuals.
