| abdominal reflexes | Contraction of the muscles of the abdominal wall upon stimulation of the skin (superficial a. Reflex's) or tapping neighboring bony structures (deep a. Reflex's). Synonym: supraumbilical reflex. (05 Mar 2000) |
| abdominal regions | The topographical subdivisions of the abdomen; based on subdividing the abdomen by the transpyloric, interspinous and midclavicular planes; including the right and left hypochondriac, right and left lateral, right and left inguinal, and the unpaired epigastric, umbilical and pubic regions. Synonym: regiones abdominis, abdominal zones. (05 Mar 2000) |
| abdominal respiration | Breathing effected mainly by the action of the diaphragm. (05 Mar 2000) |
| abdominal ring | The opening in the transversalis fascia through which the ductus deferens (or round ligament in the female) and gonadal vessels enter the inguinal canal. Located midway between anterior superior iliac spine and pubic tubercle, it is bounded medially by the lateral umbilical ligament (inferior epigastric vessels) and inferiorly by the inguinal ligament. Indirect inguinal hernias exit the abdominal cavity via the deep inguinal ring Synonym: annulus inguinalis profundus, abdominal ring, annulus abdominalis, internal inguinal ring. (05 Mar 2000) |
| abdominal sac | The part of the embryonic celom that becomes the abdominal cavity. (05 Mar 2000) |
| abdominal salpingectomy | Removal of one or both fallopian tubes through an abdominal incision. Synonym: celiosalpingectomy, laparosalpingectomy. (05 Mar 2000) |
| abdominal salpingo-oophorectomy | Removal of the fallopian tube and ovary through an abdominal incision. Synonym: abdominal salpingo-oophorectomy. (05 Mar 2000) |
| abdominal section | Transabdominal incision into the peritoneal cavity. Synonym: abdominal section, laparotomy, ventrotomy. Origin: celio-+ G. Tome, incision Vaginal celiotomy, opening the peritoneal cavity through the vagina. Synonym: culdotomy. (05 Mar 2000) |
| abdominal typhoid | <disease, microbiology> An infectious febrile illness usually spread by contamination of food, milk or water supplies with Salmonella typhi, either directly by sewage, indirectly by flies or by faulty personal hygiene. There are less than 600 cases per year in the us. Asymptomatic carriers harbor the organism in their gallbladder and excrete it in their stools for years. Average incubation time is 10-14 days. Fever, diarrhoeal stools (often bloody), abdominal pain, malaise and a rose coloured rash on the upper abdomen are seen. Severe cases may progress to delirium and obtundation. Complications include glomerulonephritis. Treatment includes intravenous fluids and antibiotics (chloramphenicol or ampicillin). Vaccines are recommended for travel to endemic areas. (27 Sep 1997) |
| abdominal wall fat pad biopsy | <investigation, procedure, surgery> The removal of a small specimen of the abdominal wall fat pad for microscopic examination. Often used in the diagnosis of amyloidosis. Performed with a local anaesthetic. (25 Jun 1999) |
| abdominal zones | The topographical subdivisions of the abdomen; based on subdividing the abdomen by the transpyloric, interspinous and midclavicular planes; including the right and left hypochondriac, right and left lateral, right and left inguinal, and the unpaired epigastric, umbilical and pubic regions. Synonym: regiones abdominis, abdominal zones. (05 Mar 2000) |
| aortic aneurysm, abdominal | An aneurysm in that part of the aorta continuing from the thoracic region and giving rise to the inferior phrenic, lumbar, median sacral, mesenteric, renal, and ovarian or testicular arteries. (12 Dec 1998) |
| aponeurosis of external abdominal oblique muscle | <anatomy> Broad, flat tendinous portion of the external abdominal oblique muscle. The fleshy fibres of the muscle end in the aponeurosis along a line descending vertically from the costochondral joint of the ninth rib then turning laterally just below the level of the umbilicus toward the anterior superior iliac spine. The fibres of the aponeurosis run medially and inferiorly, contributing to the anterior wall of the sheath of the rectus abdominis muscle and decussating with those of the contralateral aponeurosis at the median linea alba. Inferomedially, the aponeurosis is attached to the upper border of the pubic symphysis, the pubic crest and pubic tubercle. Between the anterior superior iliac spine and the pubic tubercle, it is thickened and turned under, forming the inguinal ligaments. The portion of the aponeurosis attached to the pubic bone forms the superficial inguinal ring by splitting into medial and lateral crura. See: external spermatic fascia, inguinal ligament, lacunar ligament, pectineal ligament, reflected inguinal ligament, superficial inguinal ring, rectus sheath. (05 Mar 2000) |
