1. Body Membranes Contain epithelium and connective tissue
Cover body surfaces
Line body cavities
Form protective sheets around organs
Contain epithelium and connective tissue

2. 1. Cutaneous membrane = skin
Dry membrane
Outermost protective boundary
Epidermis: epithelium
________________________________
Dermis: mostly dense connective tissue

3. 2. Mucous Membranes OR Mucosa (epithelial)
Epithelium
______________________________________
Loose connective tissue
“Wet” membrane (goblet cells)
Lines all body cavities that open to the exterior body surface
Often adapted for absorption or secretion
Some secrete mucous (respiratory, digestive, reproductive), but not all (urinary)

4. 3. Serous Membranes Or Serosa
epithelium
____________________________________
areolar connective tissue
Line body cavities that are closed to the exterior of the body
Serous membranes occur in pairs separated by serous fluid
Visceral layer covers the outside of the organ
Parietal layer upper most layer

5. Names of Serous Membranes to know
Peritoneum
Abdominal cavity
Pleura
Around the lungs
Pericardium
Around the heart

6. 4. Synovial membrane Connective tissue only (no epithelium)
Lines fibrous capsules surrounding joints
Secretes a lubricating fluid
