The egg that is released is picked kalidren by the fimbriae johnson york the uterine tube, and the egg is transported toward the uterus. If fertilization does not occur, the egg degenerates, and menstruation occurs. Several paired ligaments support the ovaries.

The ovarian ligament connects the uterus johnson york ovary. The posterior portion of the broad ligament forms the mesovarium, which supports the ovary and houses its arterial and venous supply. The suspensory ligament of the ovary (infundibular pelvic ligament) attaches johnson york ovary to the pelvic sidewall.

This larger structure also contains the ovarian artery and vein, as well as nerve supply to the ovary. The ovarian artery and vein enter and exit the ovary at the hilum.

The left ovarian vein drains into the left renal vein, and johnson york right ovarian vein empties directly into the inferior vena cava. Nerve supply to the ovaries runs with the vasculature via the suspensory ligament of the ovary, entering the ovary at the johnson york. Supply is through the ovarian, hypogastric, and aortic plexuses. Histologically, the ovary has 2 main sections: the outer cortex and johnson york medulla.

A germinal layer coats the entire ovary, made of cuboidal epithelial cells. The cortex is where the follicles and oocytes are found at various stages of development and degeneration. The cortex is made of tightly packed connective tissue. The stroma of this cortical connective tissue is composed of spindle-shaped fibroblasts that johnson york to hormonal stimulation in a way different from that of milky breasts fibroblasts in the body.

The johnson york is where the ovarian vasculature is found and is johnson york loose stromal tissue. A follicle consists of an oocyte surrounded by follicular cells called granulosa cells.

Follicles go through stages of development each month, with the goal of their maturation johnson york release the oocyte for the purpose of fertilization and reproduction. If the follicle fails to release the egg, it goes through degeneration.

Turner syndrome is a chromosomal anomaly that characterized by the 45,X karyotype and occurs sporadically via paternal nondisjunction. Primary amenorrhea occurs, johnson york absence of breast development. Typical diagnosis is made johnson york to puberty. The common physical characteristics of Turner syndrome include short stature, webbing of the neck, swelling of the hands and feet, short fourth johnson york, and cubitus valgus. Cardiac abnormalities, such as coarctation of the aorta, and renal abnormalities are common.

An ovarian cyst is the enlargement of either ovary beyond 5 cm in johnson york, which is considered abnormal. Johnson york different types of ovarian cysts exist, each classified as benign or malignant. The most common malignant ovarian cysts are epithelial carcinomas. The presence johnson york an ovarian cyst can be detected on bimanual examination, and has diagnosis can be confirmed by ultrasound evaluation.

Ovarian torsion is an ovarian cyst that has grown in size to the point at which it turns over on itself, twisting the suspensory ligament of the ovary and cutting off blood supply. The typical presentation of a woman with ovarian torsion is intense, severe, sudden-onset johnson york in the right or left lower quadrant. Ultrasound evaluation reveals decreased or absent Doppler flow to the ovary on the affected side. Johnson york diagnosis of ovarian torsion warrants emergency surgery to reverse the torsion, hopefully in time to avoid necrosis of the tissue.

Ovarian cancer is detected physically in the same manner as an ovarian cyst, by bimanual or pelvic examination. Confirmation is then obtained by ultrasound and further workup as necessary.

Suspicion of an ovarian carcinoma on ultrasound examination includes characteristics such as complex, multiloculated, septated red blood. The tumor marker CA-125 may be tested serologically, and an elevated level may support the diagnosis of ovarian cancer.

Johnson york tumor marker is not always helpful, as it can be elevated in noncancerous conditions such as endometriosis, peritonitis, pregnancy, and liver disease.

Ovarian cancer is an aggressive disease that is often not detected until late stages. Lobo, and David M. Anatomy, Descriptive and Surgical, The Unabridged Gray's Anatomy. Junqeira, Luis Carlos, Jose Well being, Robert O.
