The only ring shaped cervical vertebra present in human body is atlas, having articulations with occipital and axis vertebra. Presence of dorsal and ventral arches is responsible for its typical shape. On the sides where transverse processes are there, one foramen on each side named Foramen transversarium is present. 120 macerated dry atlas vertebrae were studied for the normal and accessory foramen transversarium. The present study is focused to investigate the presence of accessory foramen tranversarium in dry atlas vertebra obtained from bone banks and to understand its significance, if any.
