| reversal of organs, total | This condition (medically called situs inversus totalis) involves complete transposition (right to left reversal) of the thoracic and abdominal organs. The heart is not in its usual position in the left chest but is on the right. Specifically related to the heart, this is referred to as dextrocardia (literally, right-hearted). And the stomach, which is normally in the left upper abdomen, is on the right. In patients with situs inversus totalis, all of the chest and abdominal organs are reversed and appear in mirror image when examined or visualised by tests such as X-ray filming. Situs inversus totalis has been estimated to occur once in about 6-8,000 births. Situs inversus occurs in a rare abnormal condition that is present at birth (congenital) called kartagener's syndrome.

| circumventricular organs | Four small areas in or near the base of the brain that have fenestrated capillaries and are outside the blood-brain barrier. They are neurohypophysis, area postrema, organum vasculosum of the lamina terminalis and subfornical organ (SFO). The neurohypophysis is a neurohemal organ. The other three are chemoreceptors: area postrema triggers vomiting in response to chemical changes in plasma, organum vasculosum of the lamina terminalis senses osmolality and alters vasopressin secretion and SFO initiates drinking in response to angiotensin II.

| sense organs | The organs of special sense, including the eye, ear, olfactory organ, taste organs, and the accessory structures associated with these organs. Synonym: organa sensuum. (05 Mar 2000) |
| neurohemal organs | Brain areas from which substances enter blood e.g., the neurohypophysis from which oxytocin and vasopressin enter blood. (05 Mar 2000) |
| supernumerary organs | Organ's exceeding the normal number, which may develop from multiple foci of organization in an organ-formative field larger (originally) than that of the definitive main organ; such organ's are aberrant but frequently not a cause of disease; illness may persist if they are left in the body after therapeutic removal of the main organ, e.g., accessory spleen. Synonym: accessory organs. (05 Mar 2000) |
| internal female genital organs | The internal feminine genital organs, the ovaries, uterine tubes, uterus, and vagina. Synonym: organa genitalia feminina interna. (05 Mar 2000) |
| organs of Zuckerkandl | Small masses of chromaffin cells found near the sympathetic ganglia along the abdominal aorta. They serve as chemoreceptors responsive to oxygen, carbon dioxide, and hydrogen ion concentration, and help to control respiration. (12 Dec 1998) |
| external female genital organs | The external feminine genital organs, the vulva and clitoris. Synonym: organa genitalia feminina externa. (05 Mar 2000) |
| urinary organs | Organs involved with the formation, storage, and excretion of urine. Synonym: organa urinaria. (05 Mar 2000) |
| lymph nodes of abdominal organs | The numerous lymph nodes receiving lymph from abdominal organs located in association with the visceral branches of the aorta. Synonym: nodi lymphatici abdominis viscerales. (05 Mar 2000) |
| breast neoplasms, male | Any neoplasms of the male breast. These occur infrequently in males in developed countries, the incidence being about 1% of that in females. Two-thirds of patients present with intraductal carcinoma. The average age of onset is 60 years for men. Orchiectomy was the standard treatment but it has been replaced by tamoxifen as the initial therapy since oestrogen-receptor-positive tumours are predominant in males. Orchiectomy and mastectomy may be used if initial drug therapy is not successful. The prognosis is worse than that for females. (12 Dec 1998) |
