Question

Which of the following layers, related to female reproductive organs, is vascularised?

I. Ovarian cortex
II. Ovarian medulla
III. Germinal epithelium
IV. Tunica albuginea

• A. I and II only
• B. II, III and IV only
• C. I, III and IV only
• D. III and IV only

Answer 1

The correct option is A I and II only

Ovarian cortex, ovarian medulla, germinal eoithelium and tunica albuginea are all parts of the female primary sex organ, the ovaries. In humans, ovaries are almond-shaped organs lying in the upper pelvic cavity of the females.

From outside to the inside, the ovaries are composed of germinal epithelium tunica albuginea ovarian cortex and ovarian medulla.

The innermost layer of the ovary is the medulla. It consists of more loosely arranged connective tissues and contains blood vessels, lymphatic vessels.

The region outer to the ovarian medulla is the ovarian cortex. It consists of dense irregular connective tissues that surround the ovarian follicles. It is a highly vascular layer.

The outermost layer is formed by the germinal epithelium which is made up of cuboidal epithelial cells. Epithelial tissues are generally avascular.

Inner to germinal epithelium lies the tunica albuginea. It is composed of connective tissues but is an avascular layer.
