Ordinary cells and intermediate cells are both types of epithelial cells found in various tissues of the body. However, there are some key differences between the two:
1. Structure: Ordinary cells are the simplest form of epithelial cells and have a cuboidal or columnar shape. They are typically single-layered and closely packed together. Intermediate cells, on the other hand, are slightly more complex in structure and have a larger and more irregular shape.
2. Function: Ordinary cells primarily function in absorption, secretion, and protection. They often line the surfaces of organs and structures, forming barriers and selectively allowing the passage of substances. Intermediate cells have a more specialized function in some tissues, such as transporting fluids or providing structural support.
3. Location: Ordinary cells are commonly found in tissues that require a high degree of absorption and secretion, such as the lining of the intestines, kidneys, and glands. Intermediate cells are often found in tissues that require mechanical support or are involved in fluid transport, such as the urinary bladder, respiratory system, and gallbladder.
4. Nucleus and cytoplasm: Ordinary cells usually have a single, centrally located nucleus within their cytoplasm, which contains all the genetic material. Intermediate cells, on the other hand, may have multiple nuclei or a larger, irregularly shaped nucleus.
5. Specializations: Ordinary cells can have microvilli or cilia on their apical surface to increase their surface area or facilitate movement, respectively. Intermediate cells, depending on their specific function, may have specializations such as tight junctions to create a more impermeable barrier, or special transport proteins for fluid or ion exchange.
Overall, while ordinary cells are the simpler and more common type of epithelial cell, intermediate cells have unique structural and functional characteristics that allow them to perform specialized tasks in specific tissues.
