The foramina

The foramen [f. vertebrale] carved out for the dorsal medulla in these vertebrae is smaller than the ones in the vertebrae that rest upon them to the degree that the dorsal medulla becomes narrower and thinner (E-F in fig. 1, ch. 11, Bk. 4) over its entire length because of the nerves that lead off from it. The foramen [f. intervertebrale] (Q in the fig. for ch. 14) carved on both sides of the vertebra to let out a nerve and to admit a vein and an artery is almost entirely made by the higher vertebra which forms its top and sides, while the vertebra below forms only the lower portion of the foramen.
