| focal and segmental hyalinosis | <nephrology> A kidney disorder that results in fibrosis and scarring in the kidney glomerulus. The cause is unknown but some cases can result from reflux nephropathy. The clinical manifestation of this kidney disorder is nephrotic syndrome. Symptoms include weight gain, swelling, hypertension and foamy urine. High blood cholesterol and triglyceride levels are also seen with this disorder. Treatment has included the use of corticosteroids and immunosuppressives. Antihypertensive agents and diuretics may also be necessary. Over one-half will develop chronic renal failure within 10 years of diagnosis. (27 Sep 1997) |

| apical | <anatomy> Relating to or located at the tip (an apex). (09 Oct 1997) |
| apical abscess | <dentistry> A dental abscess that occurs at the end of a root, caused by tooth decay which invades the pulp chamber of the tooth. Involvement of the pulp chamber can lead to destruction of the nerve and blood vessels which supply the tooth. These infections must be treated by root canal therapy (endodontics) or tooth extraction. (27 Sep 1997) |
| apical angle | The angle between two plane surfaces of a prism. Synonym: refracting angle of a prism. (05 Mar 2000) |
| apical-aortic conduit | A valved conduit between the LV apex and aorta, used to treat severe otherwise unapproachable LV outflow tract obstruction. (05 Mar 2000) |
| apical area | The area about the root end of a tooth. (05 Mar 2000) |
| apical branch | The apical branch of the following: 1) superior lobar branches of left and right pulmonary arteries; 2) left superior pulmonary vein. Synonym: ramus superior. Synonym: ramus apicalis. (05 Mar 2000) |
| apical cap | <radiology> Local pleural thickening at lung apex, ascribed incorrectly to TB, aetiology: non-specific fibrous scarring (most common), Pancoast tumour (12 Dec 1998) |
| apical complex | A set of anterior structures that characterise one or several developmental stages of members of the protozoan phylum Apicomplexa; includes the following structures, visible by electron microscopy: polar ring, conoid, rhoptries, micronemes, and subpellicular tubules. (05 Mar 2000) |
| apical dendrite | The dendritic process extending from the apex of a pyramidal cell of the cerebral cortex toward the surface. Synonym: apical dendrite. (05 Mar 2000) |
| apical dental foramen | The opening at the apex of the root of a tooth that gives passage to the nerve and blood vessels. Synonym: foramen apicis dentis, apical dental foramen, root foramen. (05 Mar 2000) |
| apical dominance | <plant biology> Growth inhibiting effect exerted by actively growing apical bud of higher plant shoots, preventing the growth of buds further down the shoot. Thought to be mediated by the basipetal movement of auxin from the apical bud. (18 Nov 1997) |
| apical ectodermal ridge | The layer of surface ectodermal cells at the apex of the embryonic limb bud; considered to exert an inductive influence on the condensation of underlying mesenchyme. (05 Mar 2000) |
| apical foramen of tooth | The opening at the apex of the root of a tooth that gives passage to the nerve and blood vessels. Synonym: foramen apicis dentis, apical dental foramen, root foramen. (05 Mar 2000) |
