What kind of muscle causes a joint to straighten when it contracts?
The muscle that causes a joint to straighten when it contracts is called an extensor.

For example, the triceps muscle is an extensor that straightens the elbow joint when it contracts.
Which of the extensors is one joint muscle?
The extensor that is considered a one-joint muscle is the extensor carpi radialis longus. Unlike other extensors that cross multiple joints, the extensor carpi radialis longus primarily acts on the wrist joint, aiding in wrist extension and abduction. This specificity allows it to play a key role in wrist movements without influencing the elbow joint.
What muscles cause the joints to straighten?

And the elbow joint is straightened with the tricep muscle (back of the arm)LigamentsPerhaps extensor muscles. (ligaments function to hold joints together, they are not muscles.)
