  2. Thick skin is missing the stratum corneum
  3. Thick skin has an additional layer called the stratum lucidum
  4. None of the above

2. In what epidermal layer does keratinization begin?

  2. Stratum spinosum
  3. Stratum granulosum
  4. None of the above

3. Which of the following properties of skin help defend against bacteria?

  1. The presence of dendritic cells
  2. The presence of defensins
  3. The presence of bacteriocidal sweat/sebum
  4. All of the above

4. Which layer of the epidermis is typically the thickest? (20-30 layers of dead cells)

  1. Stratum spinosum
  2. Stratum corneum
  3. Stratum basale
  4. None of the above

5. What is the order of the strata that a needle would pass through when inserted into thin skin?

a. Corneum, granulosum, spinosum, basale

b. Corneum spinosum, granulosum, basale

6. Which of the following glands is most highly influenced by stress/hormones?

a. goblet cells

b. mucous glands lining the trachea

c. eccrine sweat glands on the forehead

d. sebaceous/oil glands

c. The Dermis

d. none of the above

T or F

11. The skin holds roughly 15% of the body’s total blood on average

12. The epidermis contains some capillaries

13. Hair follicles are located in the dermis

14.  Apocrine glands are the most common time of sweat glands

15. The hypodermis allows the skin to move over the underlying fascia, thus adding to the skin’s resistance to injury

16. Thanks to lamellar granules and other lipid/protein compounds, the skin is able to prevent water loss, and function as a physical barrier between the body’s interior and the exterior environment.

17. Melanin and DNA serve as two biological barriers to damage from UV rays

18. The skin is very basic (alkaline/low pH) and therefore prevents bacteria from living on it

19. The cell layer that divides living tissue from dead tissue in the skin is the stratum basale

20. Melanocytes are found in the stratum basale
