Tissue Identification Quiz

1. A tracheal lining has cilia and goblet cells. Its nuclei lie at different heights, although every cell contacts the basement membrane. What tissue is this?

2. A tendon sample contains densely packed, parallel collagen fibers with flattened fibroblast nuclei aligned between them. Which tissue is it?

3. A small-intestine sample shows one layer of tall cells, a brush border, and scattered goblet cells. Which tissue best matches these features?

4. A slide contains large cells with clear-looking central spaces where lipid was removed during preparation, leaving nuclei pushed to the edge. What tissue is shown?

5. An alveolar wall in the lung consists of one thin layer of flattened cells, allowing rapid gas diffusion. Which tissue is being described?

6. A specimen contains large cell bodies with long processes, surrounded by numerous smaller supporting-cell nuclei. Which primary tissue type best matches this pattern?

7. A kidney tubule is lined by a single layer of cube-shaped cells with round, centrally placed nuclei. How should this tissue be classified?

8. A specimen forms a continuous surface of tightly packed cells with very little extracellular matrix. Which primary tissue type is it?

9. A bladder specimen changes appearance as the organ fills, and its relaxed surface contains rounded, dome-shaped cells. Which epithelium permits this stretching?

10. A muscle sample has long, unbranched, striated fibers with many nuclei positioned near the cell membrane. Which muscle tissue is present?

11. A section from the esophagus has many cell layers, with flattened surface cells that remain moist and retain nuclei. Which lining is present?

12. A hard tissue specimen shows concentric rings of matrix surrounding central canals that contain blood vessels. How should it be identified?

13. Cells sit in lacunae within a smooth, glassy-looking matrix whose fine collagen fibers are not readily visible. Which tissue is this?

14. The wall of a hollow digestive organ contains spindle-shaped cells with central nuclei and no visible striations. Which tissue is most likely?

15. A striated muscle specimen contains branching cells, mostly central nuclei, and dark junctions between neighboring cells. What is it?

16. In the dermis, thick collagen bundles run in many directions, helping the skin resist tension from several angles. Which tissue best fits?
