Senile features in the skeleton of an aged Japanese monkey

Abstract

The senile features in the skeleton of a male Japanese monkey, who is presumed to be about 40 years old, were examined in comparison with younger individuals. As for the skull, every part is constructed solidly, and the sutures around the temporal and parietal bones are for the most part closed. In the dentition many of the front teeth are destroyed or lost, and the cheek teeth are severely worn. In the vertebrae, the annular epiphyseal discs unite completely with the body at its anterior and posterior surfaces, and the porosity and deformation of the bodies are remarkable. The hip bones, in the pelvis, unite with each other by solid ossification of the pubic symphysis. The long bones of the anterior and posterior limbs are marked by their general thickness, the rugged increase of bone around the joints, especially in the arms, and the complete union of each epiphysis with the shaft through the ossification of the epiphyseal cartilage. These senile features furnish a clue as to the establishment of a criterion for age estimation in Japanese monkeys.
