The morphological peculiarities of the glands of human trachea at the bifurcation of this organ

The aim of the investigation was to study the structurae peculiarites of the glands of human trachea at its bifurcation. The glands of te trachea from 52 people of different age and sex were studied by macro-mocroscopic methods. At the total preparationsof the trachea the multi cellular cells were coloured by R.D. Sinelnikov's method. The localization of the numerous glands at the cartilaginous and membranaceus walls of the trachea is different. Along the cartilaginous wall of the trachea the glands are arranged in one layer, but at the membranaceus wall- in thre layers. At the cartilaginous wall the initial parts of the glands are located at submucosa and fibrous membrane, at the membranaceus wall- at all layers of the trachea and principal bronchi. At the bifurcation of the trachea the initial parts of the glands from the glandular muff. The compactness of the localization of mouth of the glands is more at the bifurca¬tion of trachea than near this region
