Skin and Body Membranes
by Mohammad Raiss Mammad
1. Skin and Body Membranes
2. Covers surfaces line body cavities, and form protective sheet around organs
3. Function of Body Membranes
4. Line or cover the surfaces
5. Protect Body surface
6. Lubricate Body Surfaces
7. Membranes Classification
8. Cutaneous membrane
9. Mucous membrane
10. Serous membrane
11. A dry membrane
12. Epithelial membranes
13. Outermost protective boundary
14. Cutaneous membrane = skin
15. Superficial epidermis
16. Keratinized stratified squamous epithelium
17. Underlying dermis
18. Mostly dense (fibrous) connective tissue
19. Surface epithelium
20. Underlying loose connective tissue (lamina propria)
21. Lines all body cavities that open to the exterior body surface
22. Often adapted for absorption or secretion
23. Wet membranes bathed in secretions
24. Surface simple squamous epithelium
25. Underlying areolar connective tissue
26. Lines open body cavities that are closed to the exterior of the body
27. Occur in pairs – parietal and visceral
28. Serous layers separated by serous fluid
29. Specific serous membranes
30. Peritoneum
31. Pericardium
32. Pleura
33. Abdominal cavity
34. Around the lungs
35. Around the hear
36. Connective Tissue Membrane
37. Synovial membrane
38. Areolar connective tissue only
39. Lines fibrous capsules surrounding joints
40. Line small sac of connective tissue called bursae and the tube-like tendon sheaths
41. Mechanical Damgae
42. Thermal Damage
43. Protective And Cushioning
44. Aids in heat regulation
45. Aids in excretion of salts, urea and uric acid
46. Integumentary System
47. Skin derivatives
48. Sweat glands
49. Oil glands
50. Hairs
51. Nails
52. Skin
53. Function of Skin
54. Protects deeper tissues from:
55. Chemical Damage
56. Bacterial Damage
57. Ultraviolet Radiation
58. Dessication
59. Waterproof
60. Sythesize Vit. D
61. Contains sensory receptors
62. Skin Sructure
63. Epidermis – outer layer
64. Stratified squamous epithelium
65. Dermis
66. Dense connective tissue
67. Both firmly connected but can separate such as in a blister
68. Deep to dermis is the hypodermis
69. Not part of the skin
70. Anchors skin to underlying organs
71. Composed mostly of adipose tissue
72. Serves as shock absorber and insulation for deeper tissues
