Chapter 4 Objectives

  • Classification of Body Membranes (pp. 92-94)
    • List the general functions of each membrane type - cutaneous, mucous, serous, and synovial - and give its location in the body.
    • Compare the structure (tissue makeup) of the major membrane types.
  • Integumentary System (Skin) (pp. 94-105)
    • List several important functions of the integumentary system and explain how these functions are accomplished.
    • When provided with a model or diagram of the skin, recognize and name the following skin structures:epidermis, dermis (papillary and reticular layers), hair and hair follicle, sebaceous gland, and sweat gland.
    • Name the layers of the epidermis and describe the characteristics of each.
    • Describe the distribution and function of the epidermal derivatives - sebaceous glands, sweat glands, and hair.
    • Name the factors that determine skin color and describe the function of melanin.
    • Differentiate between first-, second-, and third-degree burns.
    • Explain the importance of the "rule of nines."
    • Summarize the characteristics of basal cell carcinoma, squamous cell carcinoma, and malignant melanoma.
  • Developmental Aspects of Skin and Body Membranes (pp. 105-107)
    • List several examples of integumentary system aging.
