In the cortical region of the mammalian ovary, all of the following are observed under the microscope EXCEPT the
Correct answer: B. Blood vessels
- A. Oocytes
- B. Blood vessels
- C. Corpus luteum
- D. Primary follicle
Explanation
The cortical region of the mammalian ovary contains structures such as oocytes and primary follicles. The corpus luteum is located in the cortex. Blood vessels permeate the ovary to supply nutrients and remove waste. While small capillaries and vessels do supply the growing follicles (the theca interna layer is highly vascularized), the major arteries and veins are generally found in the medulla. Thus, blood vessels is the most suitable answer.
