Abdominal muscles 




  • Transversus abdominis
  • Rectus abdominis
  • Internal oblique 
  • External oblique
The rectus abdominis is surrounded by a aponeuroses - tendinous sheets- called the sheath of the rectus abdominis. These extend from the other three muscles of the abdomen. The flat abdominal muslces (transversus abdominis, internal oblique and external oblique) arise from the lateral sides of the abdomen and its tendons join at the midline forming a line of fibrous tissue called the linea alba.  

The fibres of the external oblique rolls inwards between the anterior superior iliac spine and the pubis forming the inguinal ligament. 

The abdominal muscles compress the abdomen during expiration, urination and defecation and help maintain posture.

Pleural effusion

Definition Pleural effusion is a collection of fluid in the pleural space between the visceral pleura surounding the lungs and the parietal pleural attatched to the throacic wall. Demographics Pleural effusions are relatively common, but it is a manifestation of other underlying diseases. The prevalence and incidence of pleural effusions is therefore dependent on it's cause. Pathophysiology/causes Pleural fluid is usually filtered from the parietal pleura into the pleural space, due to hydrostatic pressure from the capillaries, negative pressure in the pleural space and pleural oncotic pressure. The visceral pleura is perfused by the pulmonary system which has a lower pressure, and fluid in the pleural space is therefore drawn back in through the visceral pleura due to the higher oncotic pressure in plasma. Some of this fluid is then drained by the lymphatic system.

Fluid Management Part 1

Fluid compartments:   The body is made of about 60% water, which is divided between the intracellular and extracellular space. Fluid is distributed in these spaces by osmotic forces determined by ion distribution between the intracellular and extraceullular space. Approximately 2/3rds (40% total body weight) of the body’s fluids is distributed in the intracellular space and 1/3rd (20%)in the extracellular space.
