From Embryology
Regnier de Graaf (1641 – 1673) was a Dutch anatomist and physician who described the anatomy of the uterine tube and the development of follicles in the ovary. He was first to describe the "Graafian follicle" (preovulatory follicle) in the ovary of mammals, but erroneously believed the entire follicle to be the mammalian oocyte (egg). |
