The following picture is an illustration of the first cervical vertebrae -Os Atlas- of a horse. I made this illustration for Veterinary Osteo-Myology Book. In this page, I've tried to make annotations for the illustration, in order to make it easier for the students (reader) to identify the parts of the bone. I use the application (Flickr photo embedding utility) the way Dr. Ismael Concha does (Anatomy Lab., College of Veterinary Medicine, Oregon State University. See his project here).
