NEET PG 2019 Favorite
Anatomy of the Female Gonad: The Ovary
Some topics are really hot and favorites for students. You should know relevant facts about those topics. Our experts recommend some topics for this year’s Preparation. Based on our research it has been seen that lots of questions in NEET PG were asked in Anatomy and Obs Gynae from ovary. So we thought of pinning the most important points about the female Gonad.
These are female gonads.
Lie in the ovarian fossa bounded in front by obliterated umbilical artery and posteriorly by ureter and internal iliac artery.
In nullipara they are vertical and greyish pink in colour but in multipara it is horizontal because of the pull by the pregnant uterus.
Before ovulation they have a smooth surface ,but later they become puckered due to scars of ovulation.
Each ovary has two ends or poles the upper or tubal and lower or uterine.
There are two borders anterior or mesovarian and posterior or free.
The surfaces are medial and lateral. The medial surface is largely covered by the uterine tube. The peritoneal recess between the mesosalpinx and this surface is known as ovarian bursa.
The ovary is covered by peritoneum except along the anterior border where the two layers are reflected on to the posterior layer of broad ligament by a short fold called mesovarium.
Ligaments of Ovary:
There is also a ligament called the Infundibulopelvic/ suspensory ligament which is the lateral part of the broad ligament extending from infundibulum of uterine tube and upper pole of the ovary to the external iliac vessels.
The Ligament of Ovary is not a peritoneal ligament . It connects the lower pole of ovary to the superolateral angle of uterus. Arterial supply is by ovarian and uterine arteries.
Veins form the pampiniform plexus which condenses into a single vein on either side and drains into inferior vena cava on the right side and into the left renal vein on the other side.
Lymphatics drain into lateral aortic and preaortic nodes. Nerve supply by the ovarian plexus contains both sympathetic (T10,T11) and parasympathetic (S2,3,4). The sympathetics are for pain and vasomotor and parasympathetics are for vasodilatation.
