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 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.
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.
Muscle Origin Insertion innervation [2] Adductor brevis: Inferior pubic ramus: Medial ridge of linea aspera: Obturator nerve (L2-L4) Adductor longus: Front side of the pubic bone under the pubic tubercle: Medial ridge of linea aspera: Obturator nerve (L2-L4) Adductor magnus: Inferior pubic ramus and ischial tuberosity: Medial ridge of linea ...
Medial ridge of linea aspera and the adductor tubercle: Vastus lateralis muscle: Origin: Greater trochanter and lateral ridge of linea aspera: Vastus intermedius muscle: Origin: Front and lateral surface of femur Vastus medialis muscle: Origin: Distal part of intertrochanteric line and medial ridge of linea aspera: Short head of biceps femoris ...
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 position of the lesser trochanter close to the head of the femur is one of the defining characteristics of the Prozostrodontia, which is the clade of cynodonts including mammals and their closest non-mammaliform relatives.
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.
