1. The longitudinal growth of the human vertebral body is depicted by a series of sagittally cut specimens taken from fresh autopsy material, ranging from one of an 8-centimeter foetus to one of a twenty-three-year-old adult.
2. Longitudinal growth of the vertebral body takes place by means of true epiphysealcartilage plates, as does longiwdinal grollth in the metaphyses of long bones.
3. The vertebral ring, often observed in the roentgenograms of growing vertebrae, is all apophysis rather than an epiphysis, and takes no part in the longitudinal growth of the vertebral body.
