The answer is:

  • The squamous cells closer to the lumen are flatter while the squamous cells closer to the connective tissue are fuller and rounder.
  • Stratified squamous epithelium is always adjacent to a free space or lumen.
  • There are so many layers of cells that it would be difficult to count them precisely.

Explanation for each option:

  1. The squamous cells closer to the lumen are flatter while the squamous cells closer to the connective tissue are fuller and rounder.

    • This is correct. In stratified squamous epithelium, the cells near the surface (closer to the lumen) are flattened, while the cells near the base (closer to the connective tissue) are more cuboidal or columnar in shape.
  2. The boundary between stratified squamous epithelium and connective tissue is indistinct and hard to see.

    • This is incorrect. The boundary between stratified squamous epithelium and the underlying connective tissue is usually distinct and can be seen clearly under a microscope.
  3. Stratified squamous epithelium is always adjacent to a free space or lumen.

    • This is correct. Stratified squamous epithelium lines surfaces that are exposed to the external environment or internal cavities, such as the skin, mouth, and esophagus, and is therefore always adjacent to a free space or lumen.
  4. There are so many layers of cells that it would be difficult to count them precisely.

    • This is correct. Stratified squamous epithelium consists of multiple layers of cells, making it difficult to count the exact number of layers.
  5. The squamous cells closer to the lumen are fuller and rounder while the squamous cells closer to the connective tissue are flatter.

    • This is incorrect. The cells closer to the lumen are flatter, while those closer to the connective tissue are fuller and rounder.

Summary: The visible characteristics of stratified squamous epithelium include the flattening of cells closer to the lumen, the presence of multiple layers making it difficult to count them precisely, and its adjacency to a free space or lumen.
