This distinctive term is of importance in connection with thedevelopment of the ova and will be more particularly alluded to after-wards. On section and microscopical examination, the ovary is found to con-sist of connective tissue with the structures known as the Graafian folliclesembedded in it, along with blood-vessels, nerves, lymphatics, and someunstriped muscular fibre. These are enclosed in the epithelial coveringalready described. The connective tissue is divided into a cortical andmedullary layer ; the former lying beneath the peritoneum, the latter be-ing at and near the hilus (Fig. 23). The medullary layer is very vascular,. 24. Section through the cortical part of the ovary (Turner), e, germ epithelium; s, s, ovarian stroma;1, 1, large-sized ovarian follicles; 2, 2, middle-sized; and 3, 3, smaller-sized Graafian follicles; o, ovumwithin Graafian follicles; v, v, blood-vessels in the stroma; g, cells of membrana granulosa. and has some unstriped muscular fibre round the branches of the ovarianartery (Fig. 24). • The Graafian follicles are scattered through the whole substance of theovary. The following points should be carefully noted : a. The younger and smaller Graafian follicles lie in the cortical size is generally about -roTrth ^n-> an(^ they exist in immensenumbers. According to careful estimates, the ovary of a female infantmay contain 40,000 to 70,000 such follicles. b. The larger follicles are much fewer in number and lie deeper in theovary. Size -^h to T£oth in. c. There are also still larger follicles nearer the surface than the ANATOMY OF THE FEMA
