A number of muscles attach to the linea aspera: From the medial lip of the linea aspera and its prolongations above and below, the vastus medialis muscle originates. From the lateral lip and its upward prolongation, the vastus lateralis muscle takes origin. The adductor magnus muscle is inserted into the linea aspera, and to its lateral ...
The quadriceps muscles consist of the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. These quadriceps muscles are innervated by the femoral nerve. [ 1 ] The tibial tuberosity thus forms the terminal part of the large structure that acts as a lever to extend the knee-joint and prevents the knee from collapsing when ...
The vastus lateralis muscle arises from several areas of the femur, including the upper part of the intertrochanteric line; the lower, anterior borders of the greater trochanter, to the outer border of the gluteal tuberosity, and the upper half of the outer border of the linea aspera.
It serves as the insertion for the biceps femoris muscle (small slip). Most of the tendon of the biceps femoris inserts on the fibula. See also. Gerdy's tubercle;
The vastus lateralis is the largest and most powerful of the three vasti muscles. It arises from the several areas of the femur, including the upper part of the intertrochanteric line; the lower, anterior borders of the greater trochanter, to the outer border of the gluteal tuberosity, and the upper half of the outer border of the linea aspera.
The gluteal tuberosity is the lateral prolongation of three prolongations of the linea aspera that extending superior-ward from the superior extremity of the linea aspera [1] on the posterior surface of the femur. [2] The gluteal tuberosity takes the form of either an elongated depression [3] or a rough ridge.
The adductor magnus is inserted into the linea aspera, and to its lateral prolongation above, and its medial prolongation below. Between the vastus lateralis and the adductor magnus two muscles are attached: the gluteus maximus inserted above, and the short head of the biceps femoris arising below.
It is formed where the medial lips of the linea aspera end below at the summit of the medial condyle. It is the insertion point of the tendon of the vertical fibers of the adductor magnus muscle . [ 1 ] [ 2 ]
