The musculus gemellus inferior ( Latin for "lower twin muscle ") is one of the skeletal muscles of the thigh in the area of the hip . It arises from the ischial tuberosity. The slender muscle lies beneath its “twin”, the musculus gemellus superior , attaches from below to the end tendon of the musculus obturator internus and attaches to the trochanteric fossa of the thigh bone. It causes the thigh to rotate outwards.
In most quadrupedal mammals (cats, for example, are an exception), the two twin muscles are fused together to form a single muscle. From a comparative anatomical point of view, however, they are referred to in the plural form - Musculi gemelli .
