Description[edit | edit source]
Semimembranosis is one of a group of muscles called the Hamstrings. It is located on the posteromedial side of the thigh deep to [Semitendinosus|Semitendinosus]. Its origin is the ischial tuberosity on the inferior pelvis and the insertion is the medial tibial condyle. It's primary action is flexion of the knee joint.[1]
Origin[edit | edit source]
A strong membranous tendon attaches to the upper lateral facet on the rough part of the ischial tuberosity.[1]
Insertion[edit | edit source]
An aponeurotic tendon arises at the distal end of the semimembranosus where it narrows and attaches to a horizontal groove on the posteromedial surface of the medial tibial condyle. The tendon then passes upwards and laterally to form the oblique popliteal ligament.
A bursae separate the muscle from the medial head of the tibia and the medial head of the [Gastrocnemius|Gastrocnemius]
