Superior Articular Facets of Atlas Vertebra - Amorphological Study

Superior Articular Facets (SAF) are present on atlas vertebra facing superomedially& they occupy most of the upper surface of the lateral mass and lie obliquely, their anterior ends being always nearer to the midline than the posterior ends. This study was carried using 100 adult dry atlas vertebrae of unknown ages and sexes. The importance of such morphological studies lies in the field of kinesiology. Any variation in the articulating surfaces also affects the movements occurring at that particular joint
