    columnar epithelium which encloses the liquor foVicuJi; at one side there is a cellular eminence called the discus proligerus^ which encloses the ovum. The outer covering of the ovum is the vitelline membrmie, or zona pellvcida^ surrounding the vitdlns or yolk. At one point of the latter is seen the r/ennincd vesicle, and within this the gennincd spot. A Graafian follicle measures from ^ko to 2^ inch in diameter; a germinal spot, not over 30W i^ich. Give the arterial and venous supply of the ovaries. The ovaries are supplied by the ovarian arteries, which arise du'ectly from the aorta. The veins of the ovaiy emerge at the hilum and enter the collec- tion of veins called the '' bulb of the ovary,'' This communicates with the veins from the Fallopian tube and upper portion of the uteras, forming a collection called the pampiniform or ovarian plexus ; from this springs the ovarian vein, which, on the right side, terminates in the inferior vena cava, on the left side, in the left renal vein. The left ovarian vein has no valve at its termination. Some apply the term pampiniform plexus to all the veins in the broad ligament. Give the lymphatics and nerve supply of the ovary. The lymphatics join with those from the tube and upper portion of the uterus and terminate in the lumbar glands. The nerve sup- ply is from che inferior hypogastric plexus. What is the position of the long axis of the ovary ? This question has been much discussed. The long axis of the ovary may be regarded as lying a little obliquely to the transverse axis of the pelvis, and with a direction slightly backward. His describes the long axis as vertical, but this does not coincide with the results of autopsies where the pelvic contents have been normal. What are the functions of the ovary ? 1. The production and liberation of the ova. 2. The production of a hormone or internal secretion, which is concerned with the development of the secondary sexual characters. 3. The production of a substance in the corpus luteum, which is necessary in order that the uterine mucosa should respond to the stimulus of the pregnant ovum by transforming itself into the de- cidua.
