histology

1. Lung of premature infant is presented on electronic photomicrography of biopsy material. Collapse of the alveolar wall caused by the deficiency of surfactant was revealed. Disfunction of what cells of the alveolar wall caused it? (10, 4, 2)
7. A patient with an acute rhinitis has hyperemia and excessive mucus formation in nasal cavity. What epithelial cells of mucous membrane have the intensified activity? (6, 5)

2. An electron microphotography represents a neural origincellthat is in the epithelium of the mucous layer. Distal partthe peripheral process of the cell has a bulbous thickeningthat contain 10-12 cilia. Whatcell is it? (9, 5)
3. It is known that an important component of aerogemic barriers is a surfactant alveolar complex that prevents alveoli from collapsing during the exudation. What alveolar cells synthesizephospholipids that areused for the surfactant membranes formation? (4, 2, 11)
4. . Premature infants have syndrom of respiratory failure. Failure of what aerohematic barriere component underlies this pathology? (10)
5. At the worker of chemical manufacture after inspiration of a caustic pair death of part of ciliary epitheliocytes of bronchi was observed. What cells will take place in regeneration of this epithelium? (5, 5)
6. In the epithelium of auriferous ways there are cells with a dome-shaped apical part on their surface of which microvilli are situated. In this cell it is also observed well developed synthetic apparatus, and in the apical part - secretory granules. Name t (5, 5)
