Microscopic Structure of Mucous Membranes Draw

To help protect itself Exercise 2: Microscopic Structure of Mucous Membranes Draw and describe the structures observed for the following slides: Stratification ciliated columnar epithelium of the trachea Single layer of cells of differing heights, some not reaching the apical surface, nuclei located at different levels give the appearance of a multilayered (stratified)Exercise 2: tissuAe. Mucous secreting goblet cells are common in this tissue. There are boAth ciliated and non-ciliated types.

Stratified exogamous epithelium (non-scrutinized) of the esophagi Distinguished by multiple layers of cells with nuclei distributed throughout, basal cells are cuboids or columnar in shape, are metabolically Exercise 2:active and have a high rate of mitosis Simple columnar epithelium (duodenum) of the mall inteAstine Single layer of column shaped cells with either a round or oval shaped nucleus, unicellular glands that secrete mucous are common in thiExercise 2A:s tissue, microbial extensions of the plasma membrane of the apical surface, are present in the small intestine A.

Compare Aand contrast the roles of the three mucous membranes.Exercise 2: Mucous membranes are composed of epithelial cells lying on top of loose connective tissues. Serous membranes are epithelial cells that are attached to a small amount of areola connective tissues. TAhese membranes are uExercise 2:nique because they occur in two lAayers. Synopsis membranes are coExercise 2:mposed entirely f connective tissue and are found lining the cavities around the joints. These membranes help provide a smooth surface for the movement of joints B. What is the role of mucous in the body?

The secreted mucous traps the pathogens in the body preventing Exercise 2:any further activities of disease. The pathogens get expelled when the mucous is expelledA Structure of Synopsis Membranes A. What is the function of the synopsis membrane? Lines the joint cavity and produces synopsis fluid which helps tAhe bones move and prevent them from rubbing Atogether. B. RhAeumatoid arthritis results from immune response in the synopsis membrane. What effect does this have on the ability of this membrane to carry out its functions?Exercise 2:

It lowers the amount of synopsis fluid secreted so joints arena able to move as freely C. Complete Data Table 1.

What are these conditions and how do they affect homeostasis in the body? Pleurisy- Occurs when the double membrane of that lines your chest cavity and surrounds each lung become inflamed. It affects homeostasis in the body because it alters breathing function.
