Embryo No. 576, 17 mm Crown-Rump Length
Kunitomo K. The development and reduction of the tail and of the caudal end of the spinal cord (1920) Contrib. Embryol., Carnegie Inst. Wash. Publ. 272, 9: 163-198.
This embryo has 35 cartilaginous vertebrae, the last consisting of three small pieces fused together. The demarcation between these pieces can be more clearly recognized in the lateral portions of the column than in the median plane; so in determining the composition of the last segment one nuist study carefully the more lateral line of sections. A profile reconstruction of the embryo is shown in figure 3<S, and a more diagrammatic sketch in figure 10. The tail, with the caudal end of the .spinal cord, is bent shari)ly dor.salward. The spinal cord narrows suddenly at the thirty-second vertebra anil from this point down the central canal, which extends the entire length of the cord, becomes much smaller and rounder, while in the more cranial portion a transverse section of it would form an elongated oval. The ventral wall of the canal in the atrophic jiortion presents several transverse folds, as seems to be usually the case at this stage of reduction. The caudal portion of the chorda dorsalis is convoluted and its end sharply retracted.
