Muscle Square (Quadratus)

The Quadratus muscle is any muscle shaped like a square. One of these muscles is the quadratus femoris muscle. It is a flat quadrangular muscle that originates from the ischial tuberosity, passes next to the head of the femur and attaches to the intertrochanteric crest of the femur. This muscle rotates the thigh outward. Thus, the quadratus femoris muscle gets its name from its square-like shape and functions to rotate the hip.

Human muscles

A quadratus muscle is a muscle that was shaped like a square. It is a pair of bones that is involved in a number of important body functions. Thanks to this muscle, the back and forth movement of the leg occurs when walking, running, and jumping. All joints of the body are supplied with blood from a pair of quadratus muscles. They make it possible to expand the chest when inhaling, bending the arms when moving to a comfortable sitting position, etc. Quadratus and other shaped muscles are an important component of the human skeleton. But, contrary to the popular belief of anatomists, their appearance has nothing to do with their functional features.
