Parietal and Visceral Peritoneum

-

 The peritoneum is a large serous membrane lining the abdominal cavity.

The peritoneum is in the form of a closed sac which is invaginated by a number of viscera.

It is divided into :-

 a. outer or parietal layer

 b. inner or visceral layer

 c. Folds of peritoneum by which the viscera are suspended.














3 major difference between Parietal AND Visceral Peritoneum :-

Parietal Peritoneum:-

 1. It lines the inner surface of the abdominal and pelvic walls and the lower surface of the diaphragm.

 • It is loosely attached to the walls, and can be easily stripped.

 2. Embryologically, it is derived from the somato-pleuric layer of the lateral plate mesoderm.

 3. Its blood supply and nerve supply are the same as those of the overlying body wall.

Visceral Peritoneum :-

 1. It lines the outer surface of the viscera.

 • It is firmly attached and cannot be stripped.

 2. Embryologically, it is derived from the splanchno-pleuric layer of the lateral plate mesoderm.

3. lts blood supply and nerve supply are the same as those of the underlying viscera.

Shock- clinical features Hypotension Tachycardia Cold clammy skin Rapid shallow respiration. Drowsiness.  confusion, irritability Multi organ failure. Classification  Cardiogenic shock –  myocardial pump failure – Intrinsic myocardial damage (infarction), vent. Arrhythmias,  extrinsic comopression (cardiac tamponade) or outflow obstruction (pulmonary embolism).
