| bronchus principalis sinister | It arises at the bifurcation of the trachea, passes in front of the oesophagus and enters the hilum of the left lung where it divides into a superior lobe bronchus and an inferior lobe bronchus. It is longer, of narrower caliber, and more nearly-horizontal than the right main bronchus, hence, aspirated objects enter it less frequently. Synonym: bronchus principalis sinister. (05 Mar 2000) |

| bronchus segmentalis | 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) |
| right main bronchus | It arises at the bifurcation of the trachea and enters the hilum of the right lung, giving off the superior lobe bronchus and continuing downward to give off the middle and inferior lobe bronchi. It is shorter, of greater caliber, and more nearly-vertical than the left main bronchus, thus, aspirated objects more frequently lodge on the right side. Synonym: bronchus principalis dexter. (05 Mar 2000) |
| mucoid impaction of bronchus | Plugging of the lumen of bronchi due to thickened mucus, interfering with ventilation of corresponding lung segments and leading to characteristic clustered linear and grape-like radiologic densities and occasionally atelectasis and pneumonia; characteristically seen in cystic fibrosis but it can occur in a variety of disease states. (05 Mar 2000) |
| primary bronchus | The main bronchus arising at the tracheal bifurcation and extending into the developing lung of the embryo. (05 Mar 2000) |
| stem bronchus | The main bronchus from which the branches of the bronchial tree arise. (05 Mar 2000) |
| intermediate bronchus | The portion of the right main bronchus between the upper lobe bronchus and the origin of the middle and inferior lobe bronchi. Synonym: bronchus intermedius. (05 Mar 2000) |
| eparterial bronchus | Right superior lobe bronchus which passes above the right pulmonary artery. (05 Mar 2000) |
| left main bronchus | It arises at the bifurcation of the trachea, passes in front of the oesophagus and enters the hilum of the left lung where it divides into a superior lobe bronchus and an inferior lobe bronchus. It is longer, of narrower caliber, and more nearly-horizontal than the right main bronchus, hence, aspirated objects enter it less frequently. Synonym: bronchus principalis sinister. (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) |
| branches of segmental bronchi | Branches of segmental bronchi to the bronchopulmonary segments of the lungs. Synonym: rami bronchiales segmentorum. (05 Mar 2000) |
| mastectomy, segmental | Removal of only enough breast tissue to ensure that the margins of the resected surgical specimen are free of tumour. (12 Dec 1998) |
| 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. Of or pertaining to the segmental organs. <anatomy> Segmental duct, the tubes which primarily open into the segmental duct, some of which become the urinary tubules of the adult.

| segmental alveolar osteotomy | An intraoral surgical procedure in which segments of alveolar bone containing teeth are sectioned between, and apically to, the teeth for the repositioning of the alveolus and teeth; it may be maxillary or mandibular, and may be combined with ostectomy.
