2024年7月23日 · Bronchopulmonary segmental anatomy describes the division of the lungs into segments based on the tertiary or segmental bronchi. The trachea divides at the carina forming the left and right main stem bronchi which enter the lung substance to divide further.

2022年10月14日 · The left upper lobe (LUL) is one of two lobes in the left lung. It is separated from the left lower lobe by the left oblique fissure and subdivided into four bronchopulmonary segments, two of which represent the lingula. The left upper lobe lies in the upper aspect of the left hemithorax and contains four bronchopulmonary segments:

2018年9月4日 · LUL (4 segments): apicoposterior, anterior, superior lingula, inferior lingula. ... independent respiratory units of lung. each bronchopulmonary segment is supplied independently by: a (tertiary) segmental bronchus. a tertiary branch of pulmonary artery. carry low oxygen ("venous") blood to lungs for oxygenation. a branch of bronchial artery ...

2021年2月11日 · The lingula is a combined term for the two lingular bronchopulmonary segments of the left upper lobe: The two lingular segments are the most anterior of the segments in the left upper lobe lying below the apicoposterior and anterior segments and above the oblique fissure.

For anatomically assessing the branches and courses of the subsegmental veins in the left upper lobe (LUL), the diverse branching patterns of blood vessels and bronchi should be investigated.

2021年5月1日 · In order to understand the bronchial variations its normal anatomy has to bear in mind: The lobar bronchus of the RUL forms a trifurcation: the apical (B1), posterior (B2) and anterior (B3) bronchi. The bronchus of the middle lobe (ML) bifurcates into …

2023年5月24日 · Definition of each segment in the LUL. The LSDS and lingular segment (LS) form LUL. The LUL was sorted into the apicoposterior segment (S 1 + 2), anterior segment (S 3), superior lingular segment (S 4), and inferior lingular segment (S 5).

2018年4月3日 · Each of the secondary bronchi give rise to several bronchopulmonary segments – the functional anatomic unit of the lung parenchyma. The right and left lung each have ten of these segments which, in turn, each have a tertiary …

2020年11月3日 · Reviewed and revised 21/2/13 OVERVIEW Dave Pilcher’s 4 rules for finding where you are: the trachea is D shaped, the flat wall is posterior the RML bronchus is anterior the apical (aka superior) segmental bronchi of the lower lobes are posterior if in doubt, go back to the carina VIDEO Bronchial Tree: Segmental Anatomy from […]

2019年3月3日 · Most call the LUL upper division the “left upper lobe” and the LUL lower division “the lingula.” 21 Figure S1-14 shows that the lower or lingula division of the LUL is subdivided into two segments: the superior (#4) and the inferior (#5).
