Endothoracic fascia

Endothoracic fascia

Endothoracic fascia is a thin layer of connective tissue that lines the inner surface of the thoracic cavity. It is part of the deep fascia, which is a layer of dense connective tissue that surrounds muscles, bones, and organs. The endothoracic fascia plays a crucial role in the structure and function of the thoracic cavity, providing a smooth surface for the movement of the lungs during respiration.

Structure

The endothoracic fascia is a thin, slippery layer that lines the inside of the thoracic cavity. It is continuous with the transversalis fascia at the diaphragm and extends upwards to the root of the neck, where it is continuous with the prevertebral fascia. The endothoracic fascia separates the pleura from the muscles and bones of the thoracic wall.

Function

The main function of the endothoracic fascia is to provide a smooth, frictionless surface that allows the lungs to expand and contract during respiration. It also serves as a barrier, preventing the spread of infections or diseases from the lungs to the thoracic wall.

Clinical significance

The endothoracic fascia can be involved in various medical conditions. For example, in pleural effusion, fluid can accumulate in the potential space between the endothoracic fascia and the parietal pleura. In thoracic surgery, the endothoracic fascia is often incised to gain access to the thoracic cavity.
