Fig. 620 a and b. Transverse section through the ovary of a human embryo of 180 mm trunk length, 270 mm head-foot length

(Embryo R. Meyer 152, from the collection of Professor R. Meyer, Berlin.) X 230.

The trabecular of connective tissue have grown throughout the entire ovary and have reached the superficial epithelium. Towards the centre the meshes are wide, towards the periphery narrow. The three zones — neogenic, peripheral, and central — can still be recognized, but the superficial epithelium is indistinctly marked off from the neogenic zone. As a glance at the orientation figure shows, only the outermost layer of the central zone is drawn. In the meshes of the connective-tissue strands are ova spheres, the most of whose ova are degenerating. In the neogenic zone are numerous genitaloid cells, in the central zone already circumscribed primary follicles. In all lumina of blood-vessels a "G " is inscribed.
