Fig. 1. Profile reconstructions showing the spinal ganglia and their dorsal roots in the tail region of the human embryo
white - Last two lumbar ganglia
stippled - Sacral ganglia
solid black - coccygeal ganglia
It will be noted that in the period included between these two stages marked regressive changes have aflected the entire coccygeal region of the spinal cord, with complete disappearance of the last three coccygeal ganglia, in sharp contrast to the sacral region of the cord, which undergoes uninterrupted development. The reconstructions are taken from embryos No. 544, 11.5 mm, long, and No. 75, 30 mm. long, belonging to the Carnegie Collection.
