1. MEMBRANES & INTEGUMENTARY SYSTEM

2. MEMBRANES Cover surfaces, organs Line body cavities Protect, lubricate
Two categories
Epithelial tissue membranes
Connective tissue membrane

3. EPITHELIAL TISSUE MEMBRANES
Cutaneous
Skin (“dry”)
Mucous
E.T. & C.T.
“wet”; secretes mucus
Lines open cavities
Traps, lubricates, protects, secretes enzymes

4. Mucous Membranes

5. EPITHELIAL TISSUE MEMBRANES continued
Serous
E.T. & C.T.
“wet”; secretes serous fluid; Lines closed cavities
Folds to form two layers
Parietal – lines wall of ventral body cavity
Visceral – covers organs
Serous fluid between layers (lubricant)

6. EPITHELIAL TISSUE MEMBRANES continued
Pleura
Line pleural cavities
Surround lungs
Pericardium
Surrounds the heart
Peritoneum
Lines abdominal cavity & covers organs

7. Peritoneum

8. CONNECTIVE TISSUE MEMBRANE
Synovial
C.T. (no E.T.)
Lines joint cavities (freely movable), bursae, tendon sheaths
Synovial fluid lubricates & provides nutrients

9. Synovial Membrane

10. Integumentary - General
Organ System
Dermatology – Study of Skin Disorders

11. Integumentary - General
Largest organ by weight
Includes all 4 primary tissue types
Aids in excretion of waste products

12. Integumentary - Structure
Cutaneous Membrane (Dry)
2 Layers:
Epidermis (superficial)
Dermis (with deeper hypodermis)
Accessory Structures (glands, sensory structures, etc.)
