| lobar sclerosis | Circumscribed atrophy of the cerebral cortex. Synonym: lobar sclerosis, progressive circumscribed cerebral atrophy. (05 Mar 2000) |
| anterior inferior segmental artery of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti anterioris inferioris renis, artery of anterior {inferior segment of kidney}. (05 Mar 2000) |
| anterior superior segmental artery of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti anterioris superioris renis, artery of anterior {superior segment of kidney}. (05 Mar 2000) |

| posterior segmental artery of kidney | Origin, continuation of the posterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti posterioris renis, artery of posterior segment of kidney. (05 Mar 2000) |
| segmental | 1. Relating to, or being, a segment. 2. <anatomy> Of or pertaining to the segments of animals; as, a segmental duct; segmental papillae.

| segmental anaesthesia | Loss of sensation limited to an area supplied by one or more spinal nerve roots. (05 Mar 2000) |
| segmental arteries of kidney | The branches of the renal artery that supply the anatomical segments of kidney. Usually five in number, they are end arteries and give off interlobar, arcuate and interlobular arteries in sequence. The latter send afferent arterioles to the glomeruli as well as branches to the kidney capsule. The segmental arteries of the kidney are identified as: anterior inferior (arteriae segmenti anterioris inferioris renis ); anterior superior (arteriae segmenti anterioris superioris renis ); inferior (arteriae segmenti inferioris renis ); posterior (arteriae segmenti posterioris renis ); and superior (arteriae segmenti superioris renis ). Synonym: arteriae renis, arteries of kidney. (05 Mar 2000) |
| segmental atelectasis | Partial collapse of one or more individual pulmonary segments. (05 Mar 2000) |
| segmental bronchus | One of the divisions of the lobar bronchus that supplies a bronchopulmonary segment. In the right lung there are commonly ten: in the superior lobe, the apical (B1) segmental bronchus, bronchus segmentalis apicalis; posterior (B2) segmental bronchus, bronchus segmentalis (BII) posterior; and anterior (B3) segmental bronchus, bronchus segmentalis (BIII) anterior; in the middle lobe, lateral (B4) segmental bronchus, bronchus segmentalis (BIV) lateralis; and medial (B5) segmental bronchus, bronchus segmentalis medialis (BV); in the inferior lobe, superior (B6) segmental bronchus, bronchus segmentalis superior (BVI), medial basal (B7) segmental bronchus, bronchus segmentalis basalis medialis (BVII); anterior basal (B8) segmental bronchus, bronchus segmentalis basalis anterior (BVIII); lateral basal (B9) segmental bronchus, bronchus segmentalis basalis lateralis (BIX); and posterior basal (B10) segmental bronchus, bronchus segmentalis basalis posterior (BX). In the left lung there are commonly nine: in the superior lobe, the apicoposterior (B1+2) segmental bronchus, bronchus segmentalis apicoposterior (BI+I); anterior (B3) segmental bronchus, bronchus segmentalis anterior (BIII); superior lingular (B4) segmental bronchus, bronchus lingularis superior (BIV); and inferior lingular (B5) segmental bronchus, bronchus lingularis inferior (BV); in the inferior lobe, superior (B6) segmental bronchus, bronchus segmentalis superior (BVI); medial basal (B7) segmental bronchus, bronchus segmentalis basalis medialis (cardiacus) (BVII), anterior basal (B8) segmental bronchus, bronchus segmentalis basalis anterior (BVIII); lateral basal (B9) segmental bronchus, bronchus segmentalis basalis lateralis (BIX); and posterior basal (B10) segmental bronchus, bronchus segmentalis basalis posterior (BX). Synonym: bronchus segmentalis. (05 Mar 2000) |
| segmental demyelinating polyneuropathy | A type of polyneuropathy in which almost solely the peripheral nerve myelin is affected; can be both familial (e.g., Charcot-Marie Tooth disease, type 1), or acquired (e.g., Guillain-Barre syndrome); on motor nerve conduction studies, manifested as conduction slowing or block. Synonym: segmental demyelinating polyneuropathy. (05 Mar 2000) |
| segmental fracture | A fracture in two parts of the same bone. Synonym: double fracture. (05 Mar 2000) |
