Which of the following layers covering the secondary follicle is fibrous?
Which of the following layers covering the secondary follicle is fibrous?
Show Hint
The outer theca layer is made of fibrous connective tissue.
Updated On: Nov 12, 2026
- Theca externa
- Theca interna
- Membrana granulosa
- Cumulus oophorus
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
A secondary follicle is surrounded by a theca made of stromal cells.
Step 2: Two layers of theca
The theca interna is the inner, cellular, well-supplied layer that makes hormones. The theca externa is the outer layer of fibrous connective tissue.
Step 3: Compare the options
Membrana granulosa and cumulus oophorus are made of follicle cells, which are not fibrous.
Final Answer:
The theca externa is the fibrous layer. \[ \boxed{\text{(A) }\text{Theca externa}} \]
