CORPUSCULUM LAMELLOSUM Meaning and
Definition
-
Corpusculum lamellosum refers to a specialized structure found in the respiratory system, specifically in the lungs. The term is derived from Latin, wherein "corpusculum" means a small body or structure, and "lamellosum" refers to having thin, plate-like structures.
The corpusculum lamellosum, also known as the lamellar body, is primarily observed in the type II alveolar cells of the lungs. These cells are responsible for producing a substance called pulmonary surfactant. Pulmonary surfactant plays a vital role in the proper functioning of the respiratory system.
The corpusculum lamellosum consists of numerous membrane-bound lamellar bodies within the type II alveolar cells. These bodies contain phospholipids and proteins, which are secreted into the alveoli (air sacs) of the lungs. The secretion of pulmonary surfactant results in the reduction of surface tension in the alveoli. This decrease in surface tension prevents the alveoli from collapsing during exhalation and facilitates the expansion of the lungs during inhalation.
Maintaining the integrity of the corpusculum lamellosum is crucial for normal lung function. Any abnormalities or deficiencies in the production or secretion of pulmonary surfactant can result in respiratory distress syndrome, particularly in premature infants.
In summary, the corpusculum lamellosum refers to a structure in the respiratory system that produces and secretes pulmonary surfactant. It plays a crucial role in reducing surface tension within the alveoli, ensuring proper lung expansion and preventing collapse.
