This gallery features representative cervical (neck) & thoracic (back) vertebrae from a five year old mare. Refer back to the "Skeletal Development" page for explanations of the ossification process.
The fusion of the cranial physis is complete in the axial skeleton of the 5-year-old. The physeal line of the caudal physis is still distinguishable so final stages of mineralization are not yet complete.
