The type of muscle that bends a joint is called a flexor muscle. Flexor muscles contract to decrease the angle between two bones at a joint, facilitating movements like bending the elbow or knee. These muscles work in opposition to extensor muscles, which increase the angle at a joint.
The flex
Extension. Extension increases an angle, as in straightening a joint. During extension, the knee or elbow are straightened.
The elbow joint bends when you flex your arm, bringing your hand closer to your shoulder. It also bends when you perform activities like throwing a ball or lifting weights.
The deltoid muscle is the big muscle on the shoulder. It has three parts; the front or anterior, middle and back or posterior. It involves the shoulder joint.
A joint is moved on its axis by muscle contraction. Muscles contract to generate force, pulling on the bones that make up the joint and causing movement. The specific movement produced is determined by the type of joint and the arrangement of muscles surrounding it.

The joint between the humerus and the ulna bends the elbow.
The quadriceps muscle helps straighten and extend the leg and the hamstring helps bend the knee.
bicept
They're referring to opposite motions, if a muscle bends a joint - it's antagonist straightens it out.
extensor
By tensing.
This type of muscle contracts to bend a limb at a joint
