What is the nucleus shape of squamous epithelial cells?

• A. Elongated
• B. Spherical
• C. Oval
• D. Flat

Answer: (D)

The main idea is that cell shape influences the appearance of the nucleus. Squamous epithelial cells are very thin and plate-like, so their nucleus is flattened to fit within the limited cytoplasmic height and to help the tissue form a continuous, protective surface. That flattened (disk-like) nucleus is the most consistent with the overall flat cell shape. Elongated nuclei appear in taller, columnar cells; spherical nuclei are typical of round cells like some immune cells; oval nuclei aren’t a characteristic feature of squamous cells.
