Origin. - A tendinous band from this muscle blends with the tendon of origin of the extensor pedis, and is attached to the lower extremity of the femur between the external condyle and trochlea. The muscular division is connected with the upper and outer part of the tibia.
Insertion. - In front of the hock the tendon breaks up into several branches, which become inserted into the front of the upper extremity of the large metatarsal bone (canon) and into the small bones of the hock. One of these branches passes over a synovial membrane on the cuneiform parvum.
Action. - To flex the hock.
