CHAPTER 1: ANATOMY AND PHYSIOLOGY OF THE INTEGUMENTARY SYSTEM

++
++
1. The primary characteristic of the skin that enables it to withstand friction and shear forces is
+
++
++
a. The number of layers in the epidermis.
++
++
b. The amount of water and lipids in the interstitial spaces.
++
++
c. The reticular formation of the dermal/epidermal junction.
++
++
d. The nerve supply that alerts the body to abnormal mechanical forces.
++
++
++
++
++
2. Fibroblasts, mast cells, and macrophages, all necessary for skin renewal and regeneration, are located primarily
+
++
++
a. In the stratum basale of the epidermis.
++
++
b. In the papillary layer of the dermis.
++
++
c. In the reticular layer of the dermis.
++
++
d. Throughout all the layers of the dermis and epidermis.
++
++
++
++
++
3. The epidermal layer that is located in the palms and soles, giving them additional strength and thickness, is the
+
++
++
++
++
++
++
++
++
++
++
++
++
++
4. The epidermis prevents loss of fluid because of its dense matrix of
+
++
++
++
++
++
++
++
++
++
++
++
++
++
5. Langerhans cells contribute to innate immunity by
+
++
++
a. Pricking the bacteria cell wall and causing cytoplasmic leaks.
++
++
b. Presenting antigens to the T-leukocytes.
++
++
c. Phagocytosis of dead tissue that feeds bacteria.
++
++
d. Creating an acidic environment on the skin surface.
