ovary/ova·ry/ (o´vah-re) the female gonad: either of the paired female sexual glands in which oocytes are formed.ova´rian
ovaryEither of the two female gonads, which are located next to the fallopian tubes and serve as endocrine glands and reserves for eggs (ova) that are released monthly, from menarche to menopause.
occult primary malignancyOccult cancer, unknown primary A malignancy of unknown 1º site or origin that is symptomless, which first manifests itself as metastases or secondary–paraneoplastic phenomena, and usually has a poor prognosis; OPMs are problematic as appropriate therapy requires that the primary malignancy be eradicated, and many remain obscure despite aggressive diagnostic work-up; certain malignancies metastasize to certain sites with greater than expected frequency; in OPMs affecting the brain, the primary arises in the lungs in up to 85% Treatment Up to 30% of Pts with metastases from an occult primary adenoCA may respond to chemotherapy–mitomycin C, adriamycin, vincristine; poor response is more common in ♂ and in Pts with liver and/or infradiaphragmatic metastases
Synonym(s): ovarium [TA] , oophoron.
ovaryOne of the paired female gonads, situated in the pelvis, one on each side of the womb (uterus), just under and inward of the open ends of the FALLOPIAN TUBES. Ovaries are almond-shaped and about 3 cm long. They are the site of egg (OVUM) formation and release one or more ova each month about 14 days before the onset of the next menstrual period. This is called ovulation. See also OOCYTE, OOGONIA.
ovarythe organ that produces the female gametes by a process called GAMETOGENESIS. In mammals, it also gives rise to the CORPUS LUTEUM from the GRAAFIAN FOLLICLE after ovulation, and in vertebrates generally produces the female hormones oestrogen and progesterone. In plants, the ovary occurs at the base of the CARPEL and contains one or more OVULES. See GYNOECIUM for inferior and superior ovaries.
ovarythe female gonad, the site of production of ova; one on each side, in the pelvic cavity, close to the open end of each Fallopian tube. An ovum is discharged into one of these tubes en route for the uterus at ovulation in each menstrual cycle. The ovaries are also endocrine glands (under the influence in turn of anterior pituitary gonadotrophic hormones), secreting the female hormones oestrogen and progestogen. These have actions both widely in the body and on the reproductive organs at specific times in the menstrual cycle and during pregnancy. See also hormones; Table 1.
|Site of production||Name of hormone||Main targets||Involved in regulating:||Secretion controlled by:|
|Hypothalamus||Releasing and inhibiting hormones||Anterior pituitary (via local blood vessels)||Secretion of anterior pituitary hormones||Other brain regions; feedback re regulated hormones and their actions|
|Neurohormones released from posterior pituitary:|
|Oxytocin||Uterus, breasts||Labour and lactation||Afferent information from target organs|
|Antidiuretic hormone (ADH, vasopressin)||Kidneys||Water loss: ECF volume and osmolality||Hypothalamic osmoreceptors|
|Anterior pituitary||(Human) growth hormone (H)GH||Most cells||Growth and metabolism||Hypothalamic releasing and inhibiting hormones via local blood vessels|
|Thyroid-stimulating (TSH)||Thyroid gland||Thyroid secretions|
|Gonadotrophins||Ovary or testis||Germ cell maturation and hormone secretions|
|Adrenocorticotrophic (ACTH)||Adrenal cortex||Cortisol secretion|
|Pineal body||Melatonin||Widespread, including brain, thymus, etc.||Hypothalamus; varying light input from retina|
|Parathyroids||Parathormone||Bone, kidneys, gut||ECF [Ca2+]|
|Medulla||Heart, smooth muscle, glands||Cardiovascular and metabolic adjustments to activity and stress||Sympathetic nervous system|
|Atrial wall||Atrial natriuretic hormone||Kidneys||Blood volume; increases sodium (therefore also water) loss in urine||Stretch of atrial wall by venous pressure|
|Gonads: Testis||Androgens (mainly testosterone)||Genitalia and other tissues||Reproductive function and sex characteristics||Anterior pituitary gonadotrophins|
|Ovary||Uterus, breasts and other tissues||Menstrual cycle, pregnancy, lactation|
|Pancreas||Blood levels, storage and cellular uptake of nutrients, notably glucose, but also proteins and fats||Blood levels of nutrients; autonomic nervous system; other gastrointesinal hormones|
|Stomach||Gastrin||Gastric acid-secreting cells||Gastrointestinal functions: motility, digestive juices and other secretions||Local chemical and mechanical factors in the alimentary tract|
|Small intestine||Several GI functions including bile flow, pancreatic enzyme and exocrine secretions||Ingestion of food, distension of GI tract|
Patient discussion about ovary
Q. Dear Doctors,I had cyst in my left ovary and poped it off,after that I have a small pain every day. in HSG everything was OK.my Pop smir is ok and in histroscopy every thing was ok. would you please ask me why I have this pain?
