Question

which epithelial type is highlighted?

pseudostratified columnar epithelium
simple cuboidal epithelium
simple columnar epithelium

Explanation:

Identify the tissue structure

The micrograph shows a section of the kidney cortex, featuring renal corpuscles (glomeruli) and surrounding renal tubules. The highlighted structures (shaded in yellow) are cross-sections of renal tubules.

Analyze cellular morphology

Using the Epithelial Tissue Types concept, we observe that these tubules are lined by a single layer of cells. The cells are roughly square-shaped (cuboidal) with equal height and width, and they contain large, spherical, centrally located nuclei.

Classify the epithelium

Using the Simple Cuboidal Epithelium concept, a single layer of cube-shaped cells is classified as simple cuboidal epithelium. This tissue type is characteristically found lining the tubules of the kidneys, where it functions in absorption and secretion.

Answer:

• pseudostratified columnar epithelium
• simple cuboidal epithelium (Correct answer)
• simple columnar epithelium
• simple squamous epithelium
