| Abstract: | The observation and measurement of foramen magnum and adjacent structures on 360 skullsunearthened in Henan province show that the ovate foramen magnum is the main shape with percentage of49.72,about 39.44% of all foramen magnum belongs to narrow type on the basis of their mean length di-ameter(35.71mm),breadth diameter(29.72mm)and length-breadth index(83.4).The emergence frequen-cy of canalis condyloideus is about 80.54% and 71.66% of them is open to foramen jugulare. |
