- One of the important functions of the skin is the synthesis of vitamin D.

TOP: Functions of the Skin
- Keratin is an important skin pigment that protects against ultraviolet light.
ANS: F DIF: Application REF: Page 167 TOP: Cell Types
- The hypodermis or superficial fascia is a subcutaneous layer rich in fat and areolar tissue.
ANS: T DIF: Memorization REF: Page 172
TOP: Structure of the Skin
- The subcutaneous layer is also referred to as the superficial fascia.
ANS: T DIF: Memorization REF: Page 172
TOP: Structure of the Skin
- Melanocytes account for approximately 55% of the epidermal cells.
ANS: F DIF: Memorization REF: Page 167
TOP: Cell Types
- During the life of an individual, epidermal tissue is constantly being replaced.
ANS: T DIF: Synthesis REF: Page 168
TOP: Epidermal Growth and Repair
- Turnover time for epidermal tissue can be accelerated by injury.
ANS: T DIF: Synthesis REF: Page 168
TOP: Epidermal Growth and Repair
- Prolonged exposure to the sun causes decreased melanin production.
ANS: F DIF: Memorization REF: Page 173
TOP: Skin Color
- A primary function of the dermal-epidermal junction is to “glue” together the dermis and the epidermis.
ANS: T DIF: Memorization REF: Page 170
TOP: Dermal-Epidermal Junction
- The epidermis is referred to as the true skin.
ANS: F DIF: Memorization REF: Page 170
TOP: Dermis
- Normally about 10% to 12% of all cells in the stratum basale enter mitosis each day.
ANS: T DIF: Memorization REF: Page 168
TOP: Epidermal Growth and Repair
- Both the epidermis and the dermis continually undergo shedding and regeneration.
ANS: F DIF: Synthesis REF: Page 168 TOP: Cell Layers
- Sensory receptors are found in the epidermis.
ANS: F DIF: Application REF: Page 169 ( Table 6-1)
TOP: Dermis
- Goose pimples, elevation of the testes, and erection of the nipples result from the contraction of muscles in the dermis.
ANS: T DIF: Application REF: Page 171 TOP: Reticular Layer
- The dermis contains both voluntary and involuntary muscle fibers.
ANS: T DIF: Application REF: Page 171 TOP: Reticular Layer
- Malignant melanoma has been steadily increasing in the United States for the past 20 years.
ANS: T DIF: Synthesis REF: Page 185 TOP: Skin Cancer
- The basic ingredient in the skin that determines skin color is melanin.
ANS: T DIF: Memorization REF: Page 172
TOP: Skin Color
- Vitiligo is an acquired condition that results in loss of pigment in certain areas of the skin.
ANS: T DIF: Memorization
REF: Page 167 (Box 6-1) TOP: Vitiligo
- An increase in the enzyme tyrosinase will lead to the destruction of pigment and result in albinism.
ANS: F DIF: Synthesis REF: Page 172 | Page 173
TOP: Skin Color
- Darkening of the skin may be caused by a decrease in the secretion of adrenocorticotropic hormone.
