Question

which epithelial type is highlighted?

transitional epithelium
stratified columnar epithelium
stratified cuboidal epithelium

Explanation:

Analyze the highlighted tissue layer

The image shows a histological section of an epithelial tissue layer highlighted in yellow-orange, resting on a basement membrane and underlying connective tissue.

Identify key cellular characteristics

We observe multiple layers of cells (stratified). The apical cells (at the top surface) have a rounded, dome-like, or umbrella-shaped appearance. This shape is characteristic of Transitional Epithelium in its relaxed state, which allows the tissue to stretch and distend.

Compare with the given options

• transitional epithelium: Matches the dome-shaped surface cells and stratified arrangement.
• stratified columnar epithelium: Incorrect, as the surface cells are not tall and column-shaped.
• stratified cuboidal epithelium: Incorrect, as the surface cells are typically limited to two layers of square-shaped cells, unlike the multi-layered, dome-topped cells shown here.

Therefore, the highlighted tissue is transitional epithelium.

Answer:

• transitional epithelium (Correct answer)
• stratified columnar epithelium
• stratified cuboidal epithelium
