The muscle that causes a joint to straighten when it contracts is called an extensor. Extensors work by increasing the angle between the bones at a joint, allowing for actions such as straightening the arm or leg. For example, the triceps muscle is an extensor that straightens the elbow joint when it contracts.

What muscle causes a joint to straighten when it contracts?
The muscle that causes a joint to straighten when it contracts are the extensor muscles. These include the triceps that work with the biceps to extend the arm.

Why muscles have to work in pairs?
Skeletal muscles only pull in one direction. For this reason they always come in pairs. When one muscle in a pair contracts, to bend a joint for example, its counterpart then contracts and pulls in the opposite direction to straighten the joint out again.
What causes the joint to straighten?
The right answer is StrainThat would depend on the joint. The knee joint is straightened with the quadricep muscle (thigh). 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.)
How do skeletal muscles work as a pair to bend and straighten the arm at the elbow?
When you bend your elbow, the biceps muscle contracts. At the same time the antagonist muscle, that is the triceps muscle relaxes in synchronized manner. Vise verse action take place, when you straighten the arm at the elbow. Triceps contracts and biceps relaxes.
What is a muscle that causes a joint to bend when it contract?
A muscle that causes a joint to bend when it contracts is called a flexor. Flexor muscles, such as the biceps brachii in the upper arm, work by shortening and pulling on the bones to decrease the angle at a joint, facilitating movements like bending the elbow. In contrast, extensors are muscles that increase the angle at a joint.
Why are extensors and flexors cnsidered antagonistic muscles?
Extensors and flexors are considered antagonistic muscles because they perform opposite actions at a joint. When one muscle, such as a flexor, contracts to bend a joint, the extensor relaxes to allow that movement. Conversely, when the extensor contracts to straighten the joint, the flexor must relax. This coordinated opposition allows for smooth and controlled movements.
