Each ovary is whitish in color and located alongside the lateral wall of the uterus in a region called the ovarian fossa. The ovarian fossa is the region that is bounded by the external iliac artery and in front of the ureter and the internal iliac artery. This area is about 4 cm x 3 cm x 2 cm in size. [3] [4]
The stroma of the ovary is a unique type of connective tissue abundantly supplied with blood vessels, consisting for the most part of spindle-shaped stroma cells. These appear similar to fibroblasts. The stroma also contains ordinary connective tissue such as reticular fibers and collagen. Ovarian stroma differs from typical connective tissue ...
An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries. It secretes hormones that influence stages of the menstrual cycle . At the time of puberty , women have approximately 200,000 to 300,000 follicles, [ 1 ] [ 2 ] each with the potential to release an egg cell (ovum) at ovulation for fertilization . [ 3 ]
A depiction of the ovarian cycle in animals. In human adult females, the primordial follicle is composed of a single oocyte surrounded by a layer of closely associated granulosa cells. In early stages of the ovarian cycle, the developing follicle acquires a layer of connective tissue and associated blood vessels. This covering is called the theca.
The corpus luteum (Latin for "yellow body"; pl.: corpora lutea) is a temporary endocrine structure in female ovaries involved in the production of relatively high levels of progesterone, and moderate levels of estradiol, and inhibin A. [1] [2] It is the remains of the ovarian follicle that has released a mature ovum during a previous ovulation. [3]
A Brief Biology Breakdown. Here’s what scientists do know: The ovaries are oblong glands each about the size of a kiwi. They’re responsible for the production and secretion of at least two ...
Labeled anatomy of the human vulva and nearby structures. The vulva is of all of the external parts and tissues and includes the following: [3] Clitoris: an organ located at the top of the vulva. It consists of the body and its pea-shaped glans that is protected by the clitoral hood.
These cells are derived from the mesoderm during embryonic development and are closely related to the mesothelium of the peritoneum.The germinal epithelium gives the ovary a dull gray color as compared with the shining smoothness of the peritoneum; and the transition between the mesothelium of the peritoneum and the cuboidal cells which cover the ovary is usually marked by a line around the ...
