The posterior compartment of the thigh is one of the fascial compartments that contains the knee flexors and hip extensors known as the hamstring muscles, as well as vascular and nervous elements, particularly the sciatic nerve. ==Structure== The posterior compartment is a fascial compartment bounded by fascia. It is separated from the anterior compartment by two folds of deep fascia, known as the medial intermuscular septum and the lateral intermuscular septum.〔http://anatomy.uams.edu/topogr_lowerlimb.html〕 The muscles of the posterior compartment of the thigh are the:〔(【引用サイトリンク】title=Summary of Lower Limb )〕 * biceps femoris muscle, which consists of a short head and a long head. * semitendinosus muscle * semimembranosus muscle These muscles (or their tendons) apart from the short head of the biceps femoris, are commonly known as the hamstrings. The depression at the back of the knee, or ''kneepit'' is the popliteal fossa, colloquially called the ''ham''. The tendons of the above muscles can be felt as prominent cords on both sides of the fossa—the biceps femoris tendon on the lateral side and the semimembranosus and semitendinosus tendons on the medial side. The hamstrings flex the knee, and aided by the gluteus maximus, they extend the hip during walking and running. The semitendinosus is named for its unusually long tendon. The semimembranosus is named for the flat shape of its superior attachment. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「posterior compartment of thigh」の詳細全文を読む スポンサード リンク
