An ovary is not directly connected to its adjacent fallopian tube. When ovulation is about to occur, the sex hormones activate the fimbriae, [citation needed] causing them to swell with blood, extend, and hit the ovary in a gentle, sweeping motion. An oocyte is released from the ovary into the peritoneal cavity and the cilia of the fimbriae ...
The ovary changes structure and function beginning at puberty. [2] Since the ovaries are able to regulate hormones, they also play an important role in pregnancy and fertility . When egg cells (oocytes) are released from the fallopian tube, a variety of feedback mechanisms stimulate the endocrine system, which cause hormone levels to change. [ 10 ]
The fallopian tubes are two tubes leading from the ovaries into the uterus. On maturity of an ovum, the follicle and the ovary's wall rupture, allowing the ovum to escape and enter the fallopian tube. There it travels toward the uterus, pushed along by movements of cilia on the inner lining of the tubes. This trip takes hours or days.
In females, the uterus, fallopian tubes, ovaries and upper vagina occupy the area between the other viscera. [1] [2] The rectum is located at the back of the pelvis, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis. The pelvic cavity also contains major arteries, veins, muscles, and nerves.
The ovary is differentiated into a central part, the medulla of ovary, covered by a surface layer, the germinal epithelium. The immature ova originate from cells from the dorsal endoderm of the yolk sac. Once they have reached the gonadal ridge they are called oogonia. Development proceeds and the oogonia become fully surrounded by a layer of ...

Some sources define the adnexa as the fallopian tubes and ovaries. [1] Others include the supporting tissues". [2] Another source defines the appendages as the "regions of the true pelvis posterior to the broad ligaments". [3] One dictionary includes the fallopian tubes, ovaries, and ligaments (without specifying precisely which ligaments are ...
The testicle in the male and the ovary in the female are called the primary sex organs. [1] All other sex-related organs are known as secondary sex organs . The outer parts are known as the genitals or external genitalia , visible at birth in both sexes, [ 1 ] [ pages needed ] while the inner parts are referred to as internal genitalia , which ...
