Diaphragm Muscle

The Diaphragm Muscle is a significant structure in the human body, playing a crucial role in the respiratory system. It is a dome-shaped, muscular and fibrous structure that separates the thoracic cavity from the abdominal cavity. The diaphragm muscle is the primary muscle used in the process of inspiration, or inhalation.

Structure[edit | edit source]

The diaphragm muscle is a thin, dome-shaped structure, located just below the lungs. It is made up of two parts: the peripheral muscle part, which is composed of skeletal muscle, and the central tendon part, which is a thin but strong fibrous membrane.

Function[edit | edit source]

The primary function of the diaphragm muscle is to aid in the process of respiration. During inhalation, the diaphragm contracts and moves downwards, increasing the volume of the thoracic cavity and decreasing the pressure, allowing air to enter the lungs. During exhalation, the diaphragm relaxes and moves upwards, decreasing the volume of the thoracic cavity and increasing the pressure, forcing air out of the lungs.

Clinical Significance[edit | edit source]

The diaphragm muscle can be affected by a number of conditions, including diaphragmatic hernia, diaphragmatic paralysis, and diaphragmatic rupture. These conditions can lead to difficulty breathing and other respiratory problems.
