Exercise 8: Classification of Covering and Lining Membranes
Cutaneous Membrane: List the Tissue Types: membrane composition (epithelial/connective), Common locations, General functions.
epithelial, connective tissue;
found in the skin;
functions are: secretion, oil and sweat, waterproofing, keratin, bacteriostatic acid mantle and sebum, and protect against chemical and mechanical damage keratinization and continuity.
Mucous: List the Tissue Types: membrane composition (epithelial/connective), Common locations, General functions.
epithelial, connective tissue;
lining of the digestive, respiratory and urogenital tracts;
general functions are secretion mucus, absorption, ciliated for movement of substances.
Serous: List the Tissue Types: membrane composition (epithelial/connective), Common locations, General functions.
epithelial, connective tissue;
lining of closed ventral body cavities;
secretion serous fluid; decreases friction.
Synovial: List the Tissue Types: membrane composition (epithelial/connective), Common locations, General functions.
connective tissue;
lining of the joint cavities of freely moveable joints;
secretionsynovial fluid; decreases friction.
Membrane type in joints, bursae and tendon sheaths
synovial
Epithelium of this membrane is always simple squamous epithelium
serous
Membrane types not found in the ventral cavity
synovial
The only membrane type in which goblet cells are found
mucous
The dry membrane with keratinizing epithelium
cutaneous
"wet" membranes
mucous
Adapted for absorption and secretion
mucous
Has parietal and visceral layers
serous

Knowing that -itis is the suffix meaning "inflammation of" what do peritonitis, pleurisy and pericarditis patological conditions have in common?
all are inflammations of serous membrane
Why are these conditions accompanied by great deal of pain?
when serous membranes become inflamed, insufficient serous fluid may be produced. As a result, friction increases and adhesions may form.
