Synonym: rami mammarii laterales arteriae thoracicae lateralis. (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 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) |
