A flexor is a muscle that causes a joint to bend. In contrast, an extension is a muscle that straightens a joint.
these muscle groups either extend a joint, extensors) or contract the joint (flexors). triceps extend the elbow joint, biceps bend the elbow joint.
Probably the Biceps Brachii (commonly called Biceps).
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.
This type of muscle contracts to bend a limb at a joint

In an exoskeleton, muscles are attached externally to the skeleton, causing them to pull on the outside of the joint, which requires bilateral muscles to contract and relax in an alternating pattern to achieve movement. In an endoskeleton, muscles are attached internally to the skeleton, allowing for a more direct relationship between muscle contraction and joint movement, typically involving antagonistic muscle pairs to bend and extend the joint more efficiently.
Single joint muscles are muscles that cross and act on only one joint. They are primarily responsible for producing movement at that specific joint, such as the biceps muscle that crosses the elbow joint to bend the forearm.
A muscle that straightens a joint is called an extensor.Extensors are the muscles whose contraction extends or straightens a limb or other part of the body.Extensor muscle
When you bend your leg, the muscles in your thigh contract, pulling on the tendons that are attached to the bones in your lower leg. This causes your knee joint to flex, bringing your lower leg closer to your thigh. Additionally, the bones in the knee joint glide and rotate to allow for smooth and efficient movement.
Muscles bend and flex by moving the arm to pick up an object or even weightlifting. you know lil Wayne
your calf and shin muscle. ;)
