What is the squamous epithelium
Answers
A simple squamous epithelium is a single layer of flat cells in contact with the basal lamina (one of the two layers of the basement membrane) of the epithelium. This type of epithelium is often permeable and occurs where small molecules need to pass quickly through membranes via filtration or diffusion.
Squamous cells tend to have horizontally flattened, nearly oval-shaped nuclei because of the thin, flattened form of the cell. Squamous epithelium is found lining surfaces such as skin or alveoli in the lung, enabling simple passive diffusion as also found in the alveolar epithelium in the lungs.
Four examples of epithelial tissue disease include eczema, psoriasis, epithelial carcinoma, and severe asthma. Eczema affects the epithelial tissue of the skin, including the stratified squamous tissues, and causes inflammation of skin tissue in angry rashes and itchy welts.
Answer:
Explanation:
Squamous, or flattened, epithelial cells, very thin and irregular in outline, occur as the covering epithelium of the alveoli of the lung and of the glomeruli and capsule of the kidney.
