Nasal mucosa,cross-section. Artwork of a sequence (left to right) showing mucus production in response to infection and inflammation. The surface is at top,with epithelial cells normally covered by a thin,clear layer of mucus that helps to filter incoming air. When infection occurs,this epithelium starts to break down (second image). By the third image,thick mucus (green) is being produced by glands in the underlying layer (lamina propria). One of these glands is shown here. Swelling and inflammation is also seen. By the fourth image,the swelling has subsided,and the epithelium is starting to regenerate | |
