The thigh is between the hip and the knee. From the knee to the ankle the precise definition of the leg is called the cnemis or crus. The calf is the part in the back of the leg and the shin is the part in the front of the leg. The bipedal gait which is the ability to move standing on two feet is what the muscles are adapted to for locomotion and to give support to the rest of the body. Tendons are composed of connective tissue and form attachment of muscle to bone. The hamstring muscles consists of three and refers to; the biceps femoris, the semitendinosus, and the semimembranosus, when hamstring muscles are mentioned. Other muscles also attach to the tibia and are listed as follows.

Tibia Muscles:

• Hamstring

• Popliteus

• Soleus

• Tibialis Anterior

The tibialis anterior are the muscles that allows the ankles and toes to extend and flex. There are other muscles that attach to the fibula and are named in the list that follows.

Fibula Muscles:

• Hamstring

• Soleus

• Peroneus

One end of the muscle, the origin, attaches to the more stationary bone, while the other end of the muscle, the insertion, attaches to the more moveable part of the bone. Both the tibia and fibula are alike in that  the muscles attaching to these bones allows for the toes and ankle to both flex and extend. Tendons which are what connects the muscles to the bone and can store energy. This energy can be used when the body is in motion to allow the muscle to keep its’ shape and create more force behind the movement. Muscles and tendons work together to house and protect the ligaments. The tendons attach muscle to bone while the ligaments attach another bone to a bone.
