Diaphragm

From WikiMD's Wellness Encyclopedia

Diaphragm is a dome-shaped, muscular and fibrous structure that separates the chest cavity from the abdomen. It is the primary muscle that the body uses during the process of breathing.

Anatomy[edit | edit source]

The diaphragm is located below the lungs, with its right side higher than the left to accommodate the liver. It is attached to the spine, the ribs, and the sternum. The diaphragm is made up of two types of muscle fibers: the peripheral muscle, which is responsible for the diaphragm's shape, and the central tendon, which is the muscle's strongest part.

Function[edit | edit source]

The diaphragm plays a crucial role in breathing. When it contracts, it flattens and lowers, creating a vacuum that pulls air into the lungs. When it relaxes, it pushes air out of the lungs. It also assists in expelling vomit, feces, and urine from the body by increasing intra-abdominal pressure.

Disorders[edit | edit source]

There are several disorders that can affect the diaphragm. These include diaphragmatic hernia, diaphragmatic paralysis, and diaphragmatic eventration. Symptoms of these disorders can include shortness of breath, chest pain, and a decreased ability to exercise.

Treatment[edit | edit source]

Treatment for diaphragm disorders depends on the specific disorder and its severity. Options can include surgery, physical therapy, and medications.
