Which species have an ovulation fossa? Sheep Horse Pig Dog Cow Please select an option Incorrect. The structure of the equine ovary is reversed compared to other species. The cortex, which is where follicles develop, is in the centre and it is surrounded by a dense, richly vascularised connective tissue layer which is analagous to the medulla of other domestic mammals. The cortex reaches the surface of the ovary at the ovulation fossa, a deep indentation at the free margin. This is where mature follicles rupture in ovulation, as opposed to at various points on the surface in other domestic mammals. WikiVet Article: ovaries. Correct!

In which part of the female reproductive tract does fertilisation most commonly take place? Ampulla Ovary Uterine horn Isthmus Infundibulum Please select an option Correct! Fertilisation usually occurs in the ampulla of the oviduct, although it may also occur at the ampullary-isthmic junction and even at the infundibulum. WikiVet Article: oviduct. Incorrect. Ovulation takes place in the ovary. Fertilisation most commonly occurs in the ampulla of the oviduct, although it may also occur at the ampullary-isthmic junction and even at the infundibulum. WikiVet Article: oviduct. Incorrect. Implantation takes place in the uterine horn. Fertilisation usually occurs in the ampulla of the oviduct, although it may also occur at the ampullary-isthmic junction and even at the infundibulum. WikiVet Article: oviduct. Incorrect. The isthmus, which is found at the caudal end of the oviduct joining to the uterus, has a folded mucosa which forms a functional reservoir for sperm in the female reproductive tract. Fertilisation may sometimes occur at the ampullary-isthmic junction, but it most commonly occurs in the ampulla of the oviduct. WikiVet Article: oviduct. Incorrect. The infundibulum is the cranial end of the oviduct and it comprises of numerous fimbrae which 'pick up' the oocyte after ovulation. Fertilisation can in fact occur here occasionally, but it more usually occurs in the ampulla of the oviduct, or sometimes the ampullary-isthmic junction. WikiVet Article: oviduct.
