Colored Superior Segments of the Lungs, Superior View

Description

Seen from a superior (cranial) perspective, the right and left lungs are oriented with their apices projecting superiorly and slightly anterior to the first rib, while the costal surfaces curve laterally toward the posterior thoracic wall. Color mapping isolates the superior segments of the lower lobes (segmenta superiora, S6) on each side, positioned posteriorly and superiorly within the basal portion of the lungs, just inferior to the oblique fissures. The apical portions of the upper lobes sit more anterior and superior relative to S6, helping separate “apical” from “superior segment” terminology in segmental anatomy. A clear dorsal emphasis. Segment 6 matters because it is a common location for dependent pathology when a patient is supine, and it is a frequent target in segmentectomy planning where preservation of adjacent basal segments is desired. That posterior, superior lower-lobe position also explains why auscultation and posterior percussion findings for S6 can differ from the basilar segments, and why radiographic opacities in the posterior upper field may still localize to the lower lobe. For bronchoscopy, the superior segmental bronchi (B6) arise early from the lower-lobe bronchus and take a posterior course, a pattern that helps clinicians reconcile endobronchial anatomy with CT segment maps. Use this illustration in thoracic anatomy and radiologic anatomy teaching to reinforce lobar fissures, segmental boundaries, and the recurring confusion between the apical upper lobe and the superior segment of the lower lobe. It also fits pulmonary surgery texts and preoperative conference materials where a quick superior-view segment reference supports discussion of VATS segmentectomy, posterior approach planning, and localization of aspiration or atelectasis patterns.
