Microvilli are tiny, finger-like projections found on the surface of various cells in our body. When observed under a scanning electron microscope (SEM), these microvilli appear as delicate structures covering the gallbladder surface, enhancing its absorptive capacity. Similarly, a colored SEM image reveals their presence on white blood cells known as lymphocytes, suggesting their role in immune responses. Interestingly, it also play a crucial role in intestinal protozoan parasites' attachment and invasion into host cells. This is evident from transmission electron microscopy (TEM) images showcasing these parasites exploiting microvilli to establish infections. In sickle cell anemia patients, microscopic examination showcases red and white blood cells affected by this genetic disorder. Amongst the components visible in the model of an animal cell are microvilli protruding from the top surface. These structures aid in increasing the cell's surface area for absorption and secretion processes. The significance extends beyond normal cellular functions; they can be observed even during pathological conditions like vaginal cancer or Chlamydia infection. Scanning electron microscopy captures detailed images of cancerous vaginal cells with distinct microvilli patterns associated with disease progression. Furthermore, SEM images provide insights into foetal skin development by revealing intricate arrangements of developing tissues along with prominent microvillar formations that contribute to nutrient exchange between mother and fetus.
