The ankle bends two ways, anterior (up) and posterior (down), so it depends. The bend the ankle down (point the toe), the gastrocnemius muscle (calf) must contract. To bend the ankle up (lift the toe) the tibialis anterior muscle must contract.
your calf and shin muscle. ;)
In order to move a bone, a muscle must contract and exert force.
Repolarization
Muscle tissue is the type of tissue that can contract. This includes skeletal, smooth, and cardiac muscle tissues. Muscle contraction is a key function that enables movement and various physiological processes in the body.

the muscles are around or next to the bones, the contracting of muscles enables the bones to move. for example the muscles in your arm, when you move your arm up, the muscle underneath the bone contract (tighten) to push the bone upwards.
When the shank is flexed during walking, the gastrocnemius muscle, which is a major calf muscle, becomes lengthened. This occurs because the gastrocnemius crosses both the knee and ankle joints; as the knee flexes, the muscle must stretch to accommodate the movement. This lengthening allows for greater range of motion and contributes to the propulsion phase of walking. Additionally, the muscle can still function to stabilize the ankle and assist in balancing during the gait cycle.
The muscle tissue in the heart, known as myocardium, must contract to fill the chambers with blood. When the heart muscles contract during systole, they reduce the volume of the chambers, pushing blood out into the arteries. During diastole, the muscle relaxes, allowing the chambers to expand and fill with blood from the veins. This coordinated contraction and relaxation enable efficient circulation throughout the body.
The majority of the bladder is made of detrusor muscle. This muscle is told by the nervous system to contract when it expands. This is what causes the feeling of needing to urinate. In order to urinate the involuntary muscle the internal sphincter, and the voluntary muscle the external sphincter must both be opened. The detrusor muscle moves involuntarily, so the bladder would probably considered an involuntary muscle.
