These muscles cover the caudal aspect of the thigh and are multi-articular. They originate near the ischium and extend to the tibia and have some tendinous components that will make up the '''common calcanean tendon'''.

'''''Biceps Muscle of the thigh'''''

'''''Biceps Muscle of the thigh'''''

* The largest and most lateral of the muscles, it is superficial and covered only by fascia and skin.

 

* It consists of cranial part arising from the sacrum and sacrotuberous ligament and a small caudal part arising from the ischium.

The largest and most lateral of the muscles, it is superficial and covered only by fascia and skin. It consists of cranial part, arising from the sacrum and sacrotuberous ligament and a small caudal part arising from the ischium. The muscle is composed of multiple parts and has different points of insertion in different species.  

* The muscle is composed of multiple parts and has different points of insertion in different species.

 

* Function - Extension and abduction of the limb. The cranial part extends the hip and stifle, though the caudal part extends the hip but flexes the stifle. It also causes tarsal extension.

Origin - sacrotuberous ligament.

 

Insertion - crural fascia.

 

'''''Semitendinous'''''

'''''Semitendinous'''''

* Function - extends the hip, stifle and tarsus when the foot makes contact with the ground, therefore propulsing the animal. On a non-weightbearing leg it flexes the stifle and rotates the leg back and out.

 

* Origin - the ischial tuberosity ('''pelvic head''')

Function - extends the hip, stifle and tarsus when the foot makes contact with the ground, therefore propulsing the animal. On a non-weightbearing leg it flexes the stifle and rotates the leg back and out.

* Insertion - cranial margin of the tibia and a tendinous insertion on the calcaneal tuberosity.  

 

Origin - the ischial tuberosity ('''pelvic head''').
