Hindlimb

This muscle originates from the tuber coxae of the hip and inserts into the cranial end of the femur. Its function involves extending the hip.

This hindlimb muscle is especially large and originates from the sacrum inserting into the patella/patellar ligament. It works to extend the hip, hock, and stifle.

This muscle also extends the hip, hock, and stifle originating from from the sacrum and inserting into the calcaneus of the hindlimb.

The semimembranosus muscle is another hindlimb muscle that assists in extending the hip, hock, and stifle. It originates from the caudal vertebrae inserting into the distal end of the femur

Muscle responsible for abducting and extending the hock, originating from the tuber coxae, and inserting into the cranial ends of both the femur and the tibia.

The m. gracilis is responsible for adduction of the hindlimb and inserts into the tibia originating from the pelvic symphysis

As its name states, this hindlimb muscle adducts the limb similar to the m. gracilis. It also lies deeper to the more superficial gracilis muscle, originating from the pelvis and inserting at the femur

One of the strongest muscles, it originates from the femur and ilium, inserting at the patella. The m. quadriceps femoris is responsible for the patellar tendon reflex which allows the stifle to extend

Contracting of this muscle will cause the extension of the hock joint. Point of origin lies within the femur, inserting at the calcaneus. 

Originating from the ilium and sacrum, and inserting at the femur, this muscle is responsible for flexing the hip.
