Book One -- The things that sustain and support the entire body, and what braces and attaches them all. [the bones and the ligaments that interconnect them] | Chapter 15 On the Vertebrae of the Neck or Cervix

The vertebra is made of several bones in children.

The first neck vertebra is made of two bones joined together like epiphyses. This union appears where the anterior part of the first (M in fig. 2, L in figs. 3 and 4) is located, and where the others sharpen into a spine (X in figs. 3 and 4). The remaining cervical, thoracic, and lumbar vertebrae (the first line would run in fig. 7 from the foramen through s; the second and third from the foramen through t and t) are constructed of three parts [lamina, pediculus arcus, corpus] besides the epiphyses. One line, filled with cartilage, 126 runs along the length of the spine from the foramen of the dorsal medulla to the tip of the spine. The two others, brought from the same foramen, separate the body of the vertebra from the two transverse processes and the remaining posterior parts of the vertebra, as can be seen in a lamb or a kid. 127 I should prefer, though, that it be seen in infants, because in them injuries of the bone occur more frequently than in persons strengthened by age. This large number of bones is lost in persons more advanced in age, but the epiphyses are sometimes not so hard to make out even in the prime of life.
