Question

Ovarian bursa is enclosed by
(A) Mesovarium
(B) Mesosalpinx
(C) Proper ligament of ovary
(D) Mesometrium
Choose the correct answer from the options given below:

• A. (A), (B) and (C) only.
• B. (A), (B) and (D) only.
• C. (A), (B), (C) and (D).
• D. (A) and (B) only.

Hint:

The depth of the ovarian bursa varies by species:
- Bitch: Very deep and almost completely encloses the ovary, often containing significant fat.
- Sow: Moderately deep.
- Cow/Mare: Shallow, leaving the ovary more exposed.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
The ovarian bursa (bursa ovarica) is a peritoneal pocket or pouch of varying depth that surrounds and encloses the ovary in female mammals, playing an important role in capturing the ovulated oocyte and directing it into the infundibulum of the uterine tube.

Step 2: Detailed Explanation:
The broad ligament of the uterus (ligamentum latum uteri) is a double fold of peritoneum that suspends the female reproductive tract from the abdominal roof and pelvic walls.
It is divided into three distinct anatomical regions:
- Mesovarium (A): Suspends the ovary and forms the medial wall of the ovarian bursa.
- Mesosalpinx (B): Suspends the uterine tube (oviduct) and forms the lateral and dorsal walls of the ovarian bursa.
Together, the mesovarium and mesosalpinx form the main peritoneal pouch of the ovarian bursa.
- Proper ligament of ovary (C):
This is a fibromuscular cord extending from the uterine end of the ovary to the uterine horn.
It runs within the margin of the mesovarium and acts as an anatomical boundary that helps restrict and define the caudal limit of the ovarian bursa.
Therefore, (A), (B), and (C) contribute directly to forming and enclosing the boundaries of the ovarian bursa.
- Mesometrium (D):
This is the largest part of the broad ligament, supporting the body and horns of the uterus, and does not participate in forming the ovarian bursa.

Step 3: Final Answer:
The correct option is (A), representing (A), (B) and (C) only.
