Abstract

The atlas (first cervical vertebra) has undergone many structural modifications. It is critically located and close to the ‘life centres’. For this study, one hundred dried intact human atlas vertebrae from the Indian population were measured using a digital Vernier calliper that provides accurate resolution up to 0.01 mm. The distance between the tips of the transverse process, the outer and the inner distance between the foramen transversaria and various diameters of vertebral foramen were measured.
Materials and methods: One hundred dried human atlases of unknown sex, obtained from the Department of Anatomy GMCH Purnea, and periphery medical colleges were studied. Study duration of Two years. All samples were drawn from the Indian population. Atlases with pathological features were excluded from the study. The following parameters were measured for each atlas using a vermier caliper, That provides accurate resolutuion up to 0.01mm. as the maximum vertical distance at midline, and the maximum transverse width of the facet of the dens was measured as the maximum transverse distance.
Conclusion- studied one hundred dried first cervical  vertebra deriving from the Indian population to give us the opportunity to analyse metrical data
