The adductor magnus is a large triangular muscle, situated on the medial side of the thigh.. It consists of two parts. The portion which arises from the ischiopubic ramus (a small part of the inferior ramus of the pubis, and the inferior ramus of the ischium) is called the pubofemoral portion, adductor portion, or adductor minimus, and the portion arising from the tuberosity of the ischium is ...
The pectineus is the only adductor muscle that is innervated by the femoral nerve. The other adductor muscles are innervated by the obturator nerve [1] with the exception of a small part of the adductor magnus which is innervated by the tibial nerve. [4]
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). The pectineus is sometimes included in this group, [1] [3] and ...
The psoas is the primary hip flexor, assisted by the iliacus. The pectineus, the adductors longus, brevis, and magnus, as well as the tensor fasciae latae are also involved in flexion. The gluteus maximus is the main hip extensor, but the inferior portion of the adductor magnus also plays a role. The adductor group is responsible for hip adduction.
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 medial epicondyle of the femur is an epicondyle, a bony protrusion, located on the medial side of the femur at its distal end.. Located above the medial condyle, it bears an elevation, the adductor tubercle, [1] which serves for the attachment of the superficial part, or "tendinous insertion", of the adductor magnus. [2]
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.
An adductor hiatus is described as oval or bridging depending on the shape of the upper boundary. It can also be described as muscular or fibrous depending on whether the structure surrounding is the muscular part or the tendinous part of the adductor magnus muscle. For example, the top drawing on the right shows an oval fibrous type of ...
