Answer 13

anywhere on surface germinal epithelium (covers almost whole ovary) ***

Question 14

which species has STRAIGHT shaped uterues? **

Answer 24

bitch

Question 25

How does distance between ovary and oviduct change closer to ovulation?

Answer 25

Gets smaller via utero-ovarian ligament so oviduct can "catch" ovulated oocyte

Question 26

Type of tubouterine junction in cattle

Answer 26

Type 2. Small ligament prevents backflow from uterus toward the oviduct/abdominal cavity by keeping the tube bent

Question 27

Type of tubouterine junction in cat/mare ***

Answer 27

Type 8. tubouterine junction protrudes into tip of horn of the uterus and there is a sphincter called the OVIDUCTAL PAPILLA ****KNOW

broad ligament

Answer 28

suspends uterus. A continuation of peritoneal fold
