List of bones of the human skeleton
From Wikipedia, the free encyclopedia
A typical adult human skeleton consists of 206, 208 or more bones depending on the counting method. The count of 208 considers the sternum to be made up of three bones instead of one; manubrium, body of sternum (gladiolus) and xiphoid process. Anatomical variation may also result in the formation of more or less bones. More common variations include cervical ribs or an additional lumbar vertebra. Babies are born with around 300 to 350 bones, many of which fuse together.
