| striae olfactoriae | Three distinct fibre bands (stria medialis, stria intermedia, stria lateralis) that caudally extend the olfactory tract beyond its attachment to the olfactory trigone. The medial stria curves dorsally into the tenia tecta; the intermediate, often barely visible, extends straight back and terminates in the olfactory tubercle; the lateral olfactory stria, the largest of the three, passes along the lateral side of the olfactory tubercle, curving laterally as far as the limen insulae, then sharply medially to reach the uncus of the parahippocampal gyrus where it terminates in the plexiform layer of the olfactory cortex. See: medial longitudinal stria. Synonym: striae olfactoriae, olfactory roots. (05 Mar 2000) |

| striae parallelae | Dark concentric lines crossing the enamel prisms of the teeth, seen in axial cross sections of the enamel. Synonym: brown striae, striae parallelae. (05 Mar 2000) |
| striae retinae | Concentric lines on the surface of an abnormal retina. Synonym: Paton's lines. (05 Mar 2000) |

| Knapp's striae | Tiny breaks in the elastin-filled tissue in the back of the eye (retinae). These abnormalities are visible to the doctor during an examination using a viewing instrument called an ophthalmoscope. Angioid streaks are seen in patients with pseudoxanthoma elasticum (abbreviated PXE), a rare disorder of degeneration of the elastic fibres with tiny areas of calcification in the skin, back of the eyes (retinae), and blood vessels. Angioid streaks can be associated with blindness. (12 Dec 1998) |
| abdominal | <anatomy> Pertaining to the abdomen. Origin: L. Abdominalis (18 Nov 1997) |
| abdominal abscess | <surgery> A localised pus-forming (suppurative) bacterial infection that occurs within the abdominal cavity as the result of a perforated viscus or post operative complication. Treatment requires either percutaneous or open surgical drainage. (27 Sep 1997) |
| abdominal adhesions | <surgery> Scarring that can occur within the abdomen in response to surgery or chronic inflammation. (27 Sep 1997) |
| abdominal angina | <surgery> A dull, crampy centralised abdominal pain that occurs 15-30 minutes after a meal. Associated with ischaemic bowel disease. Evaluated with mesenteric arteriography. (27 Sep 1997) |
| abdominal aorta | <anatomy> The largest arterial conduit below the diaphragm. This term refers to the portion of the aorta below the diaphragm to the bifurcation into the right and left common iliac arteries. It supplies blood to the abdominal viscera, pelvic organs and lower extremities. (20 Jun 2000) |
| abdominal aortic aneurysm | <surgery> A distended and weakened area in the wall of the abdominal aorta, more common in those who suffer from atherosclerosis. Symptoms include sudden, severe abdominal pain with radiation to the back. (27 Sep 1997) |
| abdominal aortic coarctation | <radiology> 2% of all coarctations, (most common site is thoracic: just distal to origin of L SCA), may be isolated congenital anomaly, associated with: thoracic aortic coarctation, idiopathic hypercalcaemia syndrome, rubella syndrome (ToRCHS), Takayasu arteritis, neurofibromatosis, radiation therapy, fibromuscular disease (12 Dec 1998) |
| abdominal aortic plexus | <anatomy, neurology> An autonomic plexus surrounding the abdominal aorta, directly continuous with the thoracic aortic plexus above and continued inferior to the bifurcation of the aorta as the superior hypogastric plexus. Synonym: plexus aorticus abdominalis. (05 Mar 2000) |
| abdominal apoplexy | <surgery> Mesenteric haemorrhage, thrombosis, or embolus involving the mesenteric or abdominal blood vessels. (05 Mar 2000) |
| abdominal ballottement | <procedure> Examination of the abdomen by palpation to detect excessive amounts of fluid (ascites) by causing organs to bob up and down in the fluid milieu. (05 Mar 2000) |
