The portion of lung tissue which is aerated by individual tertiary bronchus is called bronchopulmonary segment.This is supplied by separate pulmonary artery and drained by common intersegmental vein.The knowledge aboutbranching pattern of bronchial tree is important during surgical resection of segments,...
We propose a method for designing the bronchial tree where the branching process is stochastic and the diameter (d) of a branch is determined by its flow rate (Q). We use two principles: the continuum equation for flow division and a power-law relationship between d and Q, given by Q ...
With dipodial branching, the tip of the bronchus bifurcates. However, the branching modes of the human bronchial tree have not been elucidated precisely. A total of 48 samples between Carnegie stage (CS) 15 and CS23 belonging to the Kyoto Collection were used to acquire imaging data with ...
The bronchial tree is formed during the pseudo-glandular stage of lung development in a process termed lung branching morphogenesis. Coinciding with the pe... Roman,Jesse - 《Experimental Lung Research》 被引量: 209发表: 1995年 TACE-induced cleavage of NgR and p75NTR in dorsal root ganglion cu...
At 3– 4 wk of gestation in the human, the groove separates dorsoventrally from the primitive esoph- agus to form the tracheal rudiment that gives rise to two primary bronchial buds. This initial branching event is fol- lowed by 23 generations of branches via invasion into the surrounding ...
of, for example, vascular and bronchial tree structures and their drive toward efficient flow or distribution of resources explains a number of power law relationships between their branching parameters. However,” Cuntz stresses, “we’ve shown that the fractal structures of dendrites and axons are...
The branching systems in our body (vascular and bronchial trees) and those in the natural world (plants, trees, and rivers) are characterized by a fractal nature: self-similar branching patterns and recursive bifurcations. These branching networks have the increasing density of branches toward the ...

bronchial branchingsecondary pulmonary lobuleTypical models of the human bronchial tree depict regular branching. However, some anatomic studies also have revealed irregular dichotomies in the human lung. We therefore studied the patterns of bronchial branching in the human lung.We examined a normal ...
