O: Sacrum, sacrosciatic lig, ischial tuber
I: Medial aspect of the tibia and common calcanean tendon
A: Extend the coxal joint, variable cation on the genial joint, extend the tarsocrural joint (hock)
What is the OIA of semimembranosus?
O: Sacrum, sacrosciatic lig., ischial tuber
I: Medial collateral lig, medial epicondyle, medial tibial condyle
A: hip extensor, stifle flexor
What nerve innervates semimembranosus

I: Medial structures of stifle
A: Flex the coxal joint
N: saphenous
What is the OIA and nerve that innervates Gracilis?
O: Pecten pubis, ischial arch.
I: Cranial border of the tibia
A: Adduct pelvic limb, extend the tarsocrural joint
N: Obturator
What is the OIA and nerve that innervates adductor m.?
