Flank (anatomy)

Flank refers to the side of the body between the rib cage and the ilium. It is part of the many structures of the anatomy of the human body. The term is derived from the Old French flanc, which means side.

Etymology

The term "flank" is derived from the Old French flanc, which means side. It was first used in English in the early 14th century.

Anatomy

The flank is located on the side of the body between the lower rib cage and the upper part of the pelvis, known as the ilium. It is an important area in the body as it contains several vital organs including the kidneys and the spleen. The muscles in the flank area, known as the abdominal oblique muscles, play a crucial role in the movement and support of the spine.

Clinical significance

The flank area is often examined during a physical examination as it can provide clues to several health conditions. Pain in the flank area can be a sign of conditions such as kidney stones, pyelonephritis, and musculoskeletal problems. It is also the area where the kidneys are palpated during a physical examination.
