Summary
This summary is machine-generated.Facial diversity in Han Chinese populations reveals distinct northern, central, and southern groups. This study analyzed 14,838 facial traits, identifying shared and varying features that align with genetic data.
Area Of Science
- Anthropology
- Genetics
- Human Morphology
Background
- Facial phenotypic diversity in Han Chinese, the world's largest ethnic group, remains under-researched.
- Understanding facial morphology is crucial for population genetics and anthropological studies.
Purpose Of The Study
- To systematically analyze facial morphological diversity within Han Chinese populations.
- To identify shared and heterogeneous facial traits and their geographical distribution.
- To investigate phenotypic classification of Han Chinese populations and compare with genetic data.
Main Methods
- Analysis of 14,838 facial traits from 2379 Han Chinese individuals.
- Utilized a large-scale three-dimensional (3D) manual landmarking database.
- Employed computer-aided facial segmented phenotyping.
Main Results
- Identified 1560 shared facial features characterizing basic Han Chinese morphology.
- Observed significant geographical variation in facial traits, with the glabella-subalare-cheilion angle showing the greatest difference.
- Phenotypic analysis classified Han Chinese into northern, central, and southern groups, consistent with genetic findings.
Conclusions
- Han Chinese populations exhibit distinct facial morphological patterns across geographical regions.
- Central Han Chinese display intermediate facial variation between northern and southern groups.
- Findings offer insights into multidimensional phenotypes and provide a resource for phenotype-genotype association studies in East Asian populations.

The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
