Caption: Ovulation. False-colour scanning electron micrograph of the surface of the ovary at ovulation. The swollen surface at top reflects the presence of a mature Graafian follicle beneath in which the ovum is ready to be ejected into the Fallopian tube. The turgidness is caused by an enlarged cavity in the follicle, the follicular antrum, in which fluid is stored. At ovulation the mature follicle ruptures and the follicular fluid (blue) is expelled. When ovulation is over the ovulation site undergoes a transformation and becomes a gland known as the corpus luteum. Magnification: x67 at 6x7cm size. x100 at 4x5 inch.
