Skin Labeling Quiz

1. A diagram shows an adipose-rich region beneath the dermis that cushions the skin and anchors it to deeper tissues. Which label fits this region?

2. Within a hair bulb, a region of rapidly dividing epithelial cells produces the growing hair shaft. What should this region be labeled?

3. A large, onion-like sensory receptor is shown deep in the dermis or hypodermis. Which structure is being labeled?

4. In a section of thick skin from the sole, a thin translucent layer appears between the stratum granulosum and stratum corneum. What is it?

5. Which layer lies immediately beneath the epidermis and contains connective tissue, blood vessels, glands, and sensory structures?

6. On a nail diagram, a hidden growth zone beneath the proximal nail fold produces most of the nail plate. What is this zone called?

7. A bracket marks the surface layer made mainly of flattened, dead, keratin-filled cells. Which label should be attached to it?

8. A saclike cluster empties an oily secretion into the side of a hair follicle. Which gland is shown?

9. A coiled tubular gland has a duct that opens directly onto the skin surface and helps regulate body temperature. Which label is correct?

10. The thick, deeper part of the dermis is composed mainly of dense irregular connective tissue. Which label belongs there?

11. A small connective-tissue projection containing capillaries extends into the base of a hair bulb. Which structure is it?

12. A label points to the superficial portion of the dermis, where loose connective tissue forms projections toward the epidermis. Which label fits?

13. A label points to the deepest epidermal stratum, where keratinocyte division continually helps renew the epidermis. Which structure is indicated?

14. On a skin cross-section, which label belongs on the outer epithelial layer that directly faces the environment?

15. A thin band of smooth muscle runs diagonally from a hair follicle toward the superficial dermis. Which label belongs on it?

16. Fine branching sensory fibers extend into the superficial skin and detect stimuli such as pain and temperature. Which label is most appropriate?
