Question

The term 'yellow body' refers to.

• A. Corpus luteum
• B. Corpus albicans
• C. Graffian follicle
• D. Trophoblast

Hint:

Understanding the role of the corpus luteum is crucial for the study of reproductive biology and treating fertility issues.

Answer 1

The Correct Option is A

To solve the problem, we need to identify what the term "yellow body" refers to in biological terms.

1. Understanding the Yellow Body:
The term "yellow body" refers to the **Corpus luteum**, which is formed in the ovary after ovulation. The corpus luteum secretes progesterone to maintain the uterine lining for a potential pregnancy. The yellow color comes from the carotenoid pigments in the luteal cells.

2. Analyzing the Options:

• Corpus luteum: This is the correct answer. The yellow body is the corpus luteum, which forms after ovulation in the ovary.
• Corpus albicans: This refers to the scar tissue that forms after the corpus luteum degenerates, so it is not the "yellow body."
• Graffian follicle: This refers to the mature ovarian follicle before ovulation, not the "yellow body."
• Trophoblast: This refers to the layer of cells forming the outer layer of the blastocyst, unrelated to the yellow body in the ovary.

Final Answer:
The correct option is (A) Corpus luteum.
