Ovaries Flashcards
what are the lgaments of the ovaries
Two peritoneal ligaments attach to the ovary;
Suspensory ligament of ovary: fold of peritoneum extending from the mesovarium to the pelvic wall. Contains neurovascular structures.
Ligament of ovary: extends from the ovary to the fundus of the uterus. It then continues from the uterus to the connective tissue of the labium majus, as the round ligament of uterus.
what are the compontents of teh ovary
The ovary has 3 components;
Surface: The surface layer of the ovary is formed by simple cuboidal epithelium, known as germinal epithelium.
Cortex: The cortex (outer part) of the ovary is largely comprised of a connective tissue stroma. It supports thousands of follicles. Each primordial follicle contains an oocyte surrounded by a single layer of follicular cells.
Medulla: The medulla (inner part) is composed of supporting stroma and contains a rich neurovascular network which enters the hilum of ovary from the mesovarium.
main function of teh ovaries
To produce oocytes (female gametes) in preparation for fertilization.
To produce the sex steroid hormones oestrogen and progesterone, in response to pituitary gonadotrophins (LH and FSH).
how do Neurovascular structures enter the hilum of the ovary
mesovarium
how do ovaries devlop
In both the males and females, the gonads develop within the mesonephric ridge and descend through the abdomen. However, unlike the testes, the ovaries stop in the pelvis
what are ovarie s
vis.
The ovaries are paired, oval organs attached to the posterior surface of the broad ligament of the uterus by the mesovarium (a fold of peritoneum, continuous with the outer surface of the ovaries).
