What is a quadrate line?

Quadrate line is an anatomical feature of the upper thigh bone, a long bone of the thigh, which is the largest bone in the human body. The vertical altitude, which has a length of only a few centimeters, is located on the inner back of the upper femur, just below the bone known as a femoral neck. The quarate line is also known as Linea Quadrata, it is significant as a location for the muscles of Quadratus Femoris back side. This is also a place where a small number of fibers from the upper end of the adopurator's magnus muscle of the inner thigh is connected to the femur. The highest part of the shaft, located on the outside of the neck and head, forms an irregular surface known as a larger trochanter. On the back of the larger trochanter there is a place where most of the deep hip muscles are attached: between them Piriformis, Obturator Internus, Gemelli and Gluteus minimum.

division of the thigh bone from the shaft at an angle perpendicular toThe direction of the neck is an interarochanteric ridge, an increased shaft limit. This ridge orbits the femur as it descends, so it spirals down from the larger trochanter while moving diagonally, wrap the shaft under the femoral neck. The creation of a second vertical ridge, which begins approximately in the center of the interarochanteric ridge on the media rear femur, is a quadrate line. This line, which is hardly noticeable, is directed down about five centimeters from the interarochanteric ridge on the back of the aspect of the bone. It ends where it meets the peak of a smaller trochanter, a smaller rounded excellent, where the neck meets the shaft on this side of the femur.

along most lengths of the line, fibers from the muscle quadratus femoris connect to the bone. Quadratus femoris is made of reinforced surface on the back of the ischi bone of the lower pelvis known as ischial tuberosity. In the shape of a flat, wide zone, then horizontally walks out of the ischia out to the interstrochanteric areaThe thigh bone, which goes to the hip joint at its course. Some of its fibers are attached near the upper end of the interarochanteric ridge on the interarochanteric ridge, because the rest follow the quadrate line down.

The lowest part of the quadrate line leads to the highest fiber of the ADUCTOR Magnus muscle. ADUCTOR Magnus covers most of the length of the inner thigh and stretches from the bottom of the femur just above the knee joint to the ischial tuberosity and pubis bone in the lower pan. Near the peak, it emits several fibers, which are inserted along the bottom of the quadrate line under the quadrates femoris muscle.
