Question
Two of the surface modifications of epithelial cells, microvilli and commonly confused with each other. In the space below, describe how you would teach a fellow student to distinguish between these two surface modifications. Most tumors arise in cells that are constantly undergoing cell division, or mitosis (for example, skin cells). A patient has recently been diagnosed with a brain tumor. What type of cell did the tumor most likely arise from-a neuron or a glial cell? A patient has recently been diagnosed with an osteosarcoma. In the space below, explain what cells this tumor most likely across form and why.Explanation / Answer
28) Microvilli are present in the epithelium of small intestine. They increase the surface area of the intestine and helps in absorption. The length of each Microvilli is about 0.5 to 1 micro meter and diameter 0.1 micro meter.
Cilia are present in ciliated epithelial cells of lungs. They are essential for removing dirt and mucus by rhythmic sweeping movements. The length of cilia ranges from 5 to 10 micro meter and the diameter is 0.2 micro meter.
