After puberty and during the whole of the child-bearing period large and mature (or almost mature) Graafian vesicles are also foundin the cortical layer in small numbers, and also corpora lutea, the remains ofvesicles which have burst and are undergoing atrophy and absorption. Beneaththis superficial stratum other larger and more mature Graafian vesicles are foundimbedded in the ovarian stroma. These increase in size as they recede from thesurface toward a highly vascular stroma in the centre of the organ, termed themedullary substance (zona vasculosa, Waldeyer). This stroma forms the tissue ofthe hilum by which the ovary is attached and through which the blood-vesselsenter; it does not contain any Graafian vesicles. The Graafian vesicles consist of an external fibro-vascular coat connected withthe surrounding stroma of the ovary by a network of blood-vessels, and
