Tissue Quiz with Pictures

1. A histology view is described as a continuous sheet of tightly packed cells with a free surface and attachment to a basement membrane. Which broad tissue class is shown?

2. A slide shows red and white cells suspended in a fluid extracellular matrix rather than attached in a solid sheet. Which tissue is being viewed?

3. An airway sample has cilia and mucus-producing goblet cells. Its nuclei lie at different heights, although every epithelial cell contacts the basement membrane. Which tissue is this?

4. Two bladder samples were taken at different degrees of fullness. One has rounded surface cells, while the stretched sample has flatter surface cells and a thinner-looking lining. Which epithelium allows this change?

5. A specimen contains large cell bodies with prominent nuclei and long branching processes, surrounded by numerous smaller supporting cells. Which broad tissue class is represented?

6. A lung specimen shows delicate air sacs lined by a single layer of very thin, flattened cells. Which tissue is best suited to this rapid gas-exchange surface?

7. A tendon sample shows tightly packed collagen bundles running in the same direction, with flattened fibroblast nuclei between them. Which tissue best fits the description?

8. A skin specimen shows many epithelial layers topped by a surface layer of flattened, dead cells filled with keratin. Which tissue is represented?

9. A muscle specimen contains striated, branching cells with central nuclei. Dark lines cross the fibers where neighboring cells connect. What tissue is shown?

10. A tracheal support ring appears smooth and glassy, with chondrocytes sitting in lacunae and few visible fibers in the matrix. Which connective tissue is this?

11. A kidney section contains many round tubules. Each tubule is lined by one layer of cube-shaped cells with centrally placed round nuclei. What tissue lines the tubules?

12. A section from the intestinal wall shows sheets of spindle-shaped cells with single central nuclei and no visible striations. Which tissue produces the wall's involuntary contractions?

13. A lining from the esophagus has many cell layers. Cells become flatter toward the moist surface, retain their nuclei, and lack a keratin layer. What is it?

14. A specimen contains large cells whose stored lipid has been removed during preparation, leaving each cell with a clear central space and a nucleus pushed to the edge. What tissue is shown?

15. Directly beneath an epithelium, a specimen shows a loose arrangement of collagen and elastic fibers, scattered cells, abundant ground substance, and small blood vessels. Which tissue is most likely?

16. A biopsy shows long, unbranched, striated fibers with many nuclei positioned near the cell membrane. Which muscle tissue is this?
