abdominal muscle deficiency syndrome
congenital absence (partial or complete) of abdominal muscles, in which the outline of the intestines is visible through the protruding abdominal wall; in men, genitourinary anomalies (urinary tract dilation and cryptorchidism) are also found; genetics unclear.
Alternate names: prune belly, prune-belly syndrome

Abdominal muscles: A large group of muscles
in the front of the
abdomen that assists in the regular breathing movement and supports
the muscles of the
spine while lifting and keeping abdominal organs such as the
intestines in place. Abdominal muscles play a key role in exercises
such as "sit-ups." They are informally called the
removal of a myoma of the uterus through an abdominal incision.
transperitoneal removal of the kidney by an incision through the anterior abdominal wall.
abdominal ostium of uterine tube
the fimbriated or ovarian extremity of an oviduct.
Alternate names: ostium abdominale tubae uterinaeTA
Abdominal pain: Pain in the belly. Abdominal
pain can be acute or chronic. It may reflect a
major problem with one of the organs in the abdomen such as:
appendix (being inflammed = appendicitis),
(inflammed = cholecystitis),
the intestine (an ulcer that has perforated),
the spleen (that has ruptured), etc.
abdominal part of pectoralis major (muscle)
portion of pectoralis major originating from the rectus sheath.
Alternate names: pars abdominalis musculi pectoralis majorisTA
abdominal part of peripheral autonomic plexuses and ganglia
portion of the autonomic nervous system (networks composed largely of autonomic nerve fibers—but also including visceral afferent fibers—and ganglia associated with blood vessels and organs) that occur both retro- and intraperitoneally in the abdominal cavity.
Alternate names: pars abdominalis plexuum et gangliorum visceraliumTA
abdominal part of thoracic duct
the part of the thoracic duct between the cisterna chyli and the aortic hiatus of the diaphragm.
Alternate names: pars abdominalis ductus thoraciciTA
abdominal part of ureter
the part of the ureter between the renal pelvis and the brim of the pelvis.
Alternate names: pars abdominalis ureterisTA
the volume of blood within the abdomen.
the implantation and development of the ovum in the peritoneal cavity, usually secondary to an early rupture of a tubal pregnancy; very rarely, primary implantation may occur in the peritoneal cavity. The blastocyst commonly implants in the rectouterine pouch of peritoneum.
Alternate names: abdominocyesis1, intraperitoneal pregnancy
pressure surrounding the bladder; estimated from rectal, gastric, or intraperitoneal pressure.
the soft, compressible aortic pulse occurring in certain abdominal disorders.
Alternate names: pulsus abdominalis
contraction of the muscles of the abdominal wall on stimulation of the skin (superficial a. reflexs) or tapping on neighboring bony structures (deep a. reflexes).
Alternate names: supraumbilical reflex2
topographic divisions of the abdomen, as bounded by the vertical midclavicular lines and the horizontal transpyloric and interspinous (transtubercular) lines (see illustration).
Alternate names: regiones abdominisTA, abdominal zones
breathing effected mainly by the action of the diaphragm.
the part of the embryonic celom that becomes the abdominal cavity.
removal of one or both uterine tubes through an abdominal incision.
incision into the uterine tube through an opening in the abdominal wall.
an undescended testis that has never descended from the retroperineal/abdominal origin through the internal inguinal ring.
Combining form indicating the abdomen, abdominal.
mechanical stimulation (usually distention) of abdominal viscera causing changes (usually a slowing) in the heart rate or the occurrence of extrasystoles.
Paracentesis of the abdomen.
Relating to the abdomen and the genital organs.
Relating to the abdomen and pelvis, especially the combined abdominal and pelvic cavities.
the combined and continuous abdominal and pelvic cavities.
Alternate names: cavitas abdominis et pelvisTA
See Also: abdominal cavity
abdominopelvic splanchnic nerves
visceral branches of the sympathetic trunks conveying presynaptic sympathetic fibers to and visceral afferent fibers from the prevertebral ganglia and paraaortic/hypogastric plexuses for the innervation of viscera located below the diaphragm. The greater, lesser, lowest, lumbar, and sacral splanchnic nerves belong to this group.
Relating to both abdomen and perineum, as in abdominoperineal resection of the rectum.
a surgical cancer treatment involving resection of the lower sigmoid colon, rectum, anus, and surrounding skin and formation of a sigmoid colostomy; performed as a synchronous or sequential transabdominal and perineal procedure.
