The muscles of internal rotation include: of arm/humerus at shoulder. Anterior part of the deltoid muscle [1] Subscapularis [1] Teres major [1] Latissimus dorsi [1] Pectoralis major [1] of thigh/femur at hip [2] Tensor fasciae latae; Gluteus generalis; Anterior fibers of Gluteus meralis; Adductor longus and Adductor brevis; of leg at knee [3 ...
Each muscle of the lateral rotator group causes lateral rotation of the thigh. These muscles are aided by the gluteus maximus and the inferior portion of the adductor magnus. Hip muscles also play a role in maintaining the standing posture. These muscles work in an integrated system with muscles of the shoulder, neck, core, lower leg, and ...
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 .

Most of the muscle inserts behind the centre of rotation of the hip. However, its function changes in different positions of the femur. For example: If the leg is flexed, the whole muscle will flex. [5] The posterior fibres of gluteus medius contract to produce hip extension, lateral rotation and abduction.
Their primary function is abduction of the femur, while internal rotation and flexion can occur depending on the position of the femur. [4] Additionally, with the hip flexed, the gluteus minimus internally rotates the thigh. With the hip extended, gluteus minimus externally rotates the thigh. [4] [5] It is also a local stabilizer for the hip.
The gemelli muscles are the inferior gemellus muscle and the superior gemellus muscle, two small accessory fasciculi to the tendon of the internal obturator muscle.The gemelli muscles belong to the lateral rotator group of six muscles of the hip that rotate the femur in the hip joint.
The hip flexors are (in descending order of importance to the action of flexing the hip joint): [2] Collectively known as the iliopsoas or inner hip muscles: Psoas major; Iliacus muscle; Anterior compartment of thigh. Rectus femoris (part of the quadriceps muscle group) Sartorius; One of the gluteal muscles: Tensor fasciae latae; Medial ...
