8.  What is a serous membrane? © Michael D. Haight, DC

9. Serous membranes  Visceral = covers the surface of organs found in body cavities.  Parietal = lines the wall of a body cavity, much like wallpaper covers the walls of a room © Michael D. Haight, DC

11. Mucous membranes  They line body cavities that open to the exterior of the body.  The mucus keeps the area moist and lubricated.  So, where in the body are they found? © Michael D. Haight, DC

12. Mucous membranes are found in….  Respiratory tract  Digestive tract  Urinary tract  Reproductive tract  Note that the secretion is spelled mucus and the membrane is spelled mucous. © Michael D. Haight, DC

15. Did you know that skin has appendages?  Hair  Receptors (two kinds of receptor corpuscles)  Nails  Skin glands Sudoriferous = sweat Sudoriferous = sweat Eccrine and apocrineEccrine and apocrine Sebaceous glands = microscopic Sebaceous glands = microscopic http://www.wounds1.com/New s/MainStory.cfm/13 http://www.wounds1.com/New s/MainStory.cfm/13 http://www.wounds1.com/New s/MainStory.cfm/13 http://www.wounds1.com/New s/MainStory.cfm/13
