Identify the tissue at the arrow ?

• A. Simple squamous epithelium
• B. Simple columnar epithelium
• C. Simple cuboidal epithelium
• D. Transitional epithelium

Answer: (C)

Recognizing epithelial tissue type from a histology slide comes down to cell shape and how many layers are present. The arrow points to tissue where cells form a single layer with roughly equal width and height, giving them a cube-like appearance. The nuclei are round to oval and centered in each cell, and they align in a neat row on the basement membrane. This combination—one layer, cells as tall as they are wide, and central nuclei—is the hallmark of simple cuboidal epithelium. Such tissue lines small ducts and tubules and is specialized for secretion and absorption. If the tissue looked flattened with very thin cells and flattened nuclei, it would be simple squamous. If the cells were taller than wide with elongated nuclei, it would be simple columnar. Transitional epithelium would show multiple layers with surface cells that can stretch and dome-shaped cells at the surface.
