Labelled diagram of Ovary
The given image represents the labelled diagram of the sectional view of the ovary.


Parts of ovary
In the given image of the ovary the below mentioned parts are labelled:
a. Blood vessel - It supplies blood and nourishments to the ovary.
b. Primary follicle - It is the follicle with two layers of granulosa cells.
c. Tertiary follicle - Secondary follicle changes into tertiary follicle, which is characterized by a fluid filled space called antrum.
d. Graffian follicle - Mature ovarian follicles are called the Graffian follicle which ruptures and releases the secondary oocyte.
e. Ovum - Secondary oocyte arrested at the metaphase II of meiosis II is released by the rupturing of the Graaffian follicle from the ovary into the fallopian tube.
f. Corpus luteum - After ovulation, the granulosa cells and the interstitial cells of the Graffian follicle form a mass of large and yellowish conical cells called the corpus luteum. It secretes large amounts of progesterone to maintain the thickness of the endometrium.
