100 sets of the cervical vertebrae from Chongqing were observed and measured (male 58

female 42} for the sagittal and transverse diameters of the foramen of the transverse process as well as the shape of the foramen.For the shape of the transverse foramen

most of them were elliptical

but some oval

round or irregular in shape; the double transverse foramen was often occured on C6

the incidence being 13.96+ 0.92%. Author.also used 20 cases of cadavers (40 sides) to determine the diameter of the vertebral vein at the lower margin of the transverse foramen of C7 and also the diameter of the vertebral artery

vertebral vein and vertebral nerve at the lower margin of the transverse foramen of C6 and the relationrhip between them .
