The adductor magnus is a powerful adductor of the thigh, made especially active when the legs are moved from a wide spread position to one in which the legs parallel each other. The part attached to the linea aspera acts as a lateral rotator. The part which reaches the medial epicondyle acts as a medial rotator when the leg is rotated outwards ...
The adductor magnus muscle 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 muscle inserted above, and the short head of the biceps femoris muscle originating below. Between the adductor ...
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 ...
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.
Green is the medial compartment (gracilis and adductor magnus), blue is the posterior (semimembrosus to biceps c. brevis) and red is the anterior (vastus lateralis to sartorius). The fascial compartments of thigh are the three fascial compartments that divide and contain the thigh muscles.
The perforating arteries are branches of the deep artery of the thigh, [1] usually three in number, so named because they perforate the tendon of the adductor magnus to reach the back of the thigh. They pass backward near the linea aspera of the femur underneath the small tendinous arches of the adductor magnus muscle.
The adductor tubercle is a tubercle on the lower extremity of the femur. 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]
The muscles in the compartment are: gracilis; adductor longus; adductor brevis; adductor magnus; The obturator externus muscle is sometimes considered part of this group, [1] [2] [3] and sometimes excluded. [4] (Spatially, it is in this location, but functionally, it is more similar to the other lateral rotator group muscles).
