Central tendon of diaphragm

Central Tendon of Diaphragm

The Central Tendon of Diaphragm is a crucial anatomical structure in the human body. It is a thin, but strong, aponeurotic plate that forms the central part of the diaphragm, the primary muscle involved in respiration.

Structure

The Central Tendon of Diaphragm is shaped somewhat like a clover leaf, being divided into right, left, and middle leaflets. It is thinner and whiter than the muscular fibers of the diaphragm, and is devoid of any blood vessels. The central tendon is closely connected to the muscular fibers of the diaphragm, which radiate from the tendon to the peripheries of the muscle.

Function

The primary function of the Central Tendon of Diaphragm is to provide a strong and stable anchor point for the contraction of the diaphragm muscle. When the diaphragm contracts, it pulls the central tendon down, increasing the volume of the thoracic cavity and drawing air into the lungs. This is the basic mechanism of inhalation.

Clinical Significance

The Central Tendon of Diaphragm is a critical structure in the body, and its damage or dysfunction can lead to serious health problems. For example, a diaphragmatic hernia can occur if there is a defect in the central tendon, allowing abdominal organs to protrude into the thoracic cavity. This can cause severe respiratory distress and requires immediate medical attention.
