A superficial gluteus is more distinct and ‘V’ shaped. It arises from the lateral angle of the ilium and gluteal fascia and inserted to the third trochanter.
The gluteus medius extends far forwards over the longissimus dorsi muscle and is inserted to the trochanter major. It assists in back kick .
The gluteus profundus is smaller and is inserted to the inner face of the convexity.
The biceps femoris has an additional attachment to the femur on the rough surface near the trochanter tertius. It also assists in back kick.
The semitendinosus arises from the transverse process of the first 2 or 3 coccygeal vertebrae.
The sartorius does not arise from the shaft of the ilium.
The gracilis is not so extensively fused to its fellow at the origin.
The semimembranosus is large and arises from the sacro-sciatic ligament also.
The obturator internus have an iliac and sacral part, which has been called as piriformis. Its tendon passes through the lesser sciatic foramen and hence does not unite with that of the externus.
The articularis genu may not be seen as a separate muscle.
The capsularis muscle is not found in the ox is present in horse. It arises from the ilium above the origin of the outer part of the rectus femoris. Its tendon passes between vastus lateralis and intermedius and it inserted to the upper third of the anterior face of the femur and the capsular ligament of the hip. It raises the capsule during flexion of the hip.
The long digital extensor arises in common with the next muscle. It receives a little below the hock on its lateral aspect the tendon of the lateral digital extensor and extensor brevis.
The peroneus tertius (Tendo femoro-metatarsus) is entirely tendinous. The short wide tendon of insertion of the tiabialis anterior to the first tarsal bone is the cunean tendon.
The lateral digital extensor or peroneus joins the tendon of the long digital extensor.
The extensor brevis joins both the tendons of the long and lateral digital extensor.
The peroneus longus is absent.
The muscles of the posterior group resemble in general to those of the ox.
