TAILIEUCHUNG - Lecture Human anatomy (6/e): Chapter 4 - Martini, Timmons, Tallitsch

Chapter 4 - The integumentary system. After completing this chapter, you should be able to do the following: Compare the structure and functions of the skin with the underlying connective tissue, describe the four primary cell types found in the epidermis, discuss the effects of ultraviolet radiation on the skin and the role played by melanocytes in this regard,. | MARI 1X1 TIMMONS FA I. LITSCH C h a p t e r 4 The Integumentary System PowerPoint Lecture Slides prepared by Jason LaPres North Harris College Houston Texas Copyright 2009 Pearson Education Inc. publishing as Pearson Benjamin Cummings Introduction The integumentary system or integument is composed of skin hair nails sweat oil and mammary glands. Skin tells clinicians about the overall health of the body and can be used to detect some internal problems.
