How Do You Spell ISTHMUS AORTAE?

1. An isthmus aortae refers to a relatively narrow section or constriction found in the human aorta, which is the main artery that carries oxygenated blood away from the heart and distributes it to the rest of the body. Specifically, the isthmus aortae is located near the aortic arch, which is the curved portion of the aorta connecting to the heart.

   This constriction region is vital as it serves as a connection point between two important blood vessels in the circulatory system. Above the isthmus aortae lies the larger ascending aorta, which carries blood away from the heart and is responsible for supplying oxygen-rich blood to the upper body, including the brain. Below the isthmus, it transitions into the descending aorta, which carries oxygenated blood to the lower body regions.

   The isthmus aortae is significant in medical and anatomical terms, as it is a common site for several cardiovascular abnormalities and conditions. For example, coarctation of the aorta is a congenital heart defect where the aorta narrows at this location. This condition can restrict blood flow and cause various complications. Understanding the isthmus aortae's anatomy and function is crucial in diagnosing and treating such conditions effectively.

2. A constriction of the arch of the aorta just beyond the origin of the subclavian artery.

Common Misspellings for ISTHMUS AORTAE

The word "isthmus aortae" is derived from two Latin words - "isthmus" and "aortae".

The term "isthmus" (plural: "isthmi") is derived from the Greek word "isthmos", which means narrow passage or neck. In the context of anatomy, it refers to a narrow or constricted part, often connecting two larger structures.

The word "aortae" is the genitive singular form of the Latin word "aorta", which means the main artery of the body that carries oxygenated blood from the heart to the rest of the body.

So, when combined, "isthmus aortae" refers to a narrow or constricted part of the aorta, specifically the region between the ascending and descending portions of the aorta.
