16 Integumentary System Outline Intro to health professions

17 Integumentary System Composed of Skin Accessory structures Accessory structures include hair Nails Glands nerves

18 Integumentary System Main Functions Cover and protect the body Help regulate the body s temperature Excretes some of the body s waste materials Includes sensors for pain and sensation

19 Skin Functions Protects the body from injury protects the body from the intrusion of harmful microorganisms Protects the body from the ultraviolet (UV) rays of the sun helps to maintain proper internal temperature of the body Serves as a site for excretion of waste through perspiration serves as an important sensory organ

21 Skin Covers 17 to 20 square feet Variations of Thickness 1/50 inch to ¼ inch thick The skin on the back upper back is 10 times thicker than the skin on the eyelid

22 Skin Layers of the skin and what they are composed of Epidermis Dermis Subcutaneous

23 Epidermis Outer layer of skin 2 sub layers: stratum corneum, stratum germinativum Dead skin cells, melanin, 90% water repellant

24 Dermis Makes ridges known as fingerprints Blood vessels, nerve endings, sebaceous and sweat glands, hair follicles

25 Subcutaneous Fatty and fibrous tissue, blood vessels and nerves Fatty layer protects inner organs and maintains body temp.

26 Hair Pilus Hair Where you do/don t have hair All areas except soles of feet and palms Visible Portion shaft

27 Hair The root follicle Oil glands Attached to each hair Melanin Determines hair color No melanin = gray hair Baldness (alopecia) Heredity, result of disease, injury, or medical treatment

28 Glands Three types of glands Sebaceous Sudoriferous ceruminous

29 Sebaceous Dermis, base of hair follicles Secrete sebum Lubricates, softens, and protects skin from bacteria and fungi

30 Sudoriferous (sweat glands) Found almost everywhere Cools the body Diaphoresis = sweating

31 Ceruminous Found in the auditory canal of ear Secrete wax Protects ear from infection
