Axis (anatomy) The condition, where the dens is separated from the body of the axis, is called os odontoideum, and may cause nerve and circulation compression syndrome. On its anterior surface is an oval or nearly circular facet for articulation with that on the anterior arch of the atlas. On the back of the neck, and frequently extending on to its lateral surfaces, is a shallow groove for the transverse atlantal ligament which retains the process in position. The apex is pointed, and gives attachment to the apical odontoid ligament; below the apex the process is somewhat enlarged, and presents on either
Atlas of Genetics and Cytogenetics in Oncology and Haematology a cancer-prone condition and 110 "Deep Insights" on related subjects, 40,000 internal links and 730,000 external links. More than 3,300 authors have/are contributing. It includes an iconography of about 35,000 images. The Atlas is part of the genome project and participates in research on cancer epidemiology. The Atlas is accessed by: 1- researchers in cytogenetics, molecular biology, cell biology; 2- clinicians, haematologists, cytogeneticists, pathologists, from the university hospitals, indeed, but also from general hospitals where the Atlas is one of the rare free resources. Junior doctors in haematology or oncology, are also most receptive to the Atlas that they see
