Question

Cortex of ovary is made up of-
A) Areolar connective tissue
B) White fibrous connective tissue
C) Reticular fibrous tissue
D) Mucoid connective tissue

Answer 1

As seen in a cross-section of an ovary, stroma is most abundantly present in it, even in the cortex region. To answer this question, one should know the composition of stroma.

Complete Answer:
The site of oogenesis is the ovary. Ovaries are stimulated by gonadotropins secreted from the anterior pituitary. Ovaries even have endocrine function, oestrogen and progesterone are secreted by them. The ovaries have a cortex and a highly vascular medulla with coiled arteries known as helicine arteries. The layer of the ovarian stroma present immediately beneath the tunica albuginea is the cortex, which remains covered by a simple squamous mesothelium, known as the germinal epithelium. The cortex is primarily made up of reticular fibrous connective tissues, scattered in the form of antral follicles, in their primary or secondary stage. Reticulate fibres are connective tissue composed of type III collagen which is secreted by reticular cells. These fibers crosslink to form a fine meshwork called reticulin. The function of this mesh is to provide structural support in soft tissues.
Follicles contain oocytes, surrounded by epithelial cells. The ovary contains numerous primary follicles, which are mostly present at the edges of the cortex. A few follicles can also be seen present in different stages of development. Ovarian cortex tissue transplant can be performed in order to treat infertility.

Thus, the correct option is- C. reticular fibrous tissue.

Note: Ovaries are small structures, they are covered by a thick connective tissue forming the tunica albuginea. The outer portion of the ovary is its cortex. It is made up of connective tissue, mainly reticular fibres.
