Many muscles contribute to these movements: 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.
In 33% of people a supernumerary muscle is found between the adductor brevis and adductor minimus. When present, this muscle originates from the upper part of the inferior ramus of the pubis from where it runs downwards and laterally. In half of cases, it inserts into the anterior surface of the insertion aponeurosis of the adductor minimus.
Human leg. The leg is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or buttock region. The major bones of the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula. The thigh is between the hip and knee, while the calf (rear) and shin (front), or shank, are between the knee and ankle.
Structures surrounding right hip-joint. (Adductor longus at upper right.) In the human body, the adductor longus is a skeletal muscle located in the thigh. One of the adductor muscles of the hip, its main function is to adduct the thigh and it is innervated by the obturator nerve. It forms the medial wall of the femoral triangle.
The quadriceps femoris muscle (/ ˈkwɒdrɪsɛps ˈfɛmərɪs /, also called the quadriceps extensor, quadriceps or quads) is a large muscle group that includes the four prevailing muscles on the front of the thigh. It is the sole extensor muscle of the knee, forming a large fleshy mass which covers the front and sides of the femur.
The three muscles of the posterior thigh (semitendinosus, semimembranosus, biceps femoris) flex (bend) the knee, while all but the biceps femoris extend (straighten) the hip. The three 'true' hamstrings cross both the hip and the knee joint and are therefore involved in knee flexion and hip extension.
Anatomical terms of muscle. [ edit on Wikidata] The lateral rotator group is a group of six small muscles of the hip which all externally (laterally) rotate the femur in the hip joint. It consists of the following muscles: piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus. [ 1 ]
Iliopsoas. Anterior hip and thigh muscles. The iliopsoas muscle (/ ˌɪlioʊˈsoʊ.əs /; from Latin ile 'groin' and Ancient Greek ψόᾱ (psóā) 'muscles of the loins') refers to the joined psoas major and the iliacus muscles. The two muscles are separate in the abdomen, but usually merge in the thigh. They are usually given the common name ...
