Into this lutein layer sprout blood-vesselsand connective-tissue radial projections, which vascularize and support thecorpus luteum. The resultant picture of large epithelial cells, with pale stain-ing nuclei lying in contact with small thin-walled blood-vessels, corresponds tothe structural appearance commonly regarded as characteristic of organs ofinternal secretion. As will be seen, this is one of the arguments for the beliefthat the seat of the internal secretion of the ovary is in the corpus luteum. ;- :$&« %S*$$k.
