The adductor group is a collection of muscles located on the medial (inner) aspect of the thigh. While commonly associated with squeezing the legs together, their functional role is far more complex, serving as vital stabilizers for the pelvis and contributing significantly to hip extension and rotation. adductor group
: The most superficial and frequently injured muscle in the group. | Muscle | Origin | Insertion | Innervation
Adduction of the hip joint (drawing the limb toward the midline). Secondary Functions: Hip flexion, extension, and rotation (depending on hip position). Adduction of the hip joint (drawing the limb
