Applying the method of silver impregnation in modification by Bielschowsky--Gros and Lavrentiev, two main types of sensitive neural terminals have been revealed in alveolar parenchyma: 1) sensitive neural terminals of bushy type, situating in the connective tissue of the alveolar walls, immediately under flat epithelium covering them; 2) sensitive neural apparatuses with a complex structure, protruding into the alveolar lumen. They are seen as an accumulation of epithelial cells, among them fine branches of myelin neural fibres (neuroepithelial bodies) terminate. Owing to space arrangement of the terminal branchings in the first type terminals, it is possible to consider them as mechanoreceptors accepting impulses which are connected with certain shifts in the pulmonary parenchyma during the process of respiration. Peculiar structure of the second type sensitive apparatuses (neuroepithelial bodies) and their arrangement in the pulmonary alveolar lumen suggest their connection with changes in the alveolar air composition. They are considered to be airreceptors.
应用 Bielschowsky - Gros 和 Lavrentiev 改良的银浸染法，在肺泡实质中发现了两种主要类型的敏感神经末梢：1）浓密型敏感神经末梢，位于肺泡壁的结缔组织中，紧挨着覆盖它们的扁平上皮下方；2）结构复杂的敏感神经装置，突入肺泡腔。它们表现为上皮细胞的聚集，其中有髓神经纤维的细分支（神经上皮小体）终止于此。由于第一类末梢中终末分支的空间排列，可以认为它们是接受与呼吸过程中肺实质某些变化相关冲动的机械感受器。第二类敏感装置（神经上皮小体）的特殊结构及其在肺泡腔内的排列表明它们与肺泡气体成分的变化有关。它们被认为是气体感受器。
