SHAPE: It’s thin and flat with irregular curvy, wavy edges. FUNCTION: It protects underlying tissues from harm. What is the specific shape of the cells on the surface of this type of epithelium? The cells are cube shaped d) Pseudostratified Ciliated Epithelium : Pseudostratified ciliated epithelium lines the nasal cavities, trachea, and bronchi. Its function is to protect these structures, secrete mucus by goblet cells, and move mucus by cilia. Examine the slide which is a section through the trachea. The trachea, or windpipe, is the tube leading from the larynx to the bronchi of the lungs. It possesses bands of cartilage to maintain its shape (as discussed shortly); and it also has an epithelial lining of pseudostratified ciliated epithelium. This type of epithelium consists of a single row of cells . Most of these cells have a columnar shape, while other, shorter cells, which are more cuboidal. The term “pseudostratified” literally means “falsely stratified”. In other words, the epithelium looks as if it has multiple layers but it only has one layer. This is due to the fact that the cells are of differing heights. Use Figure 9 to locate the epithelium of the trachea on your slide. Observe cilia . Also, locate the oval, white cells scattered throughout this epithelium. These are goblet cells that secrete mucus into the respiratory tree. The function of mucus is to trap foreign material. 8

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
