Arteria musculophrenica

Arteria Musculophrenica is a branch of the internal thoracic artery that supplies blood to the diaphragm and the abdominal wall. It is a significant artery in the human anatomy due to its role in the circulatory system.

Anatomy

The arteria musculophrenica originates from the internal thoracic artery, which is a branch of the subclavian artery. It descends along the side of the thoracic cage, giving off several branches to the intercostal muscles and the diaphragm. The artery terminates in the abdominal wall, where it anastomoses with the inferior epigastric artery and the superficial epigastric artery.

Function

The primary function of the arteria musculophrenica is to supply oxygenated blood to the diaphragm, the primary muscle involved in respiration. It also provides blood to the muscles and skin of the lower part of the anterior thoracic wall.

Clinical significance

Due to its location and function, the arteria musculophrenica can be involved in various medical conditions. For instance, injury to this artery can lead to significant bleeding and may require surgical intervention. It can also be involved in conditions affecting the diaphragm, such as diaphragmatic hernia.
