This muscle is called the extensor muscle. There are specific names for different joints.
If a prime mover produces flexion, its antagonist will be the muscle responsible for producing extension at the same joint. They work in opposition to each other to create movement and stabilize the joint.
Contractions of the gluteus maximus muscle causes (hyper)extension of the thigh.
A flexor is a muscle that causes a joint to bend. In contrast, an extension is a muscle that straightens a joint.
If you mean hyperadduction of the joint at the knee, it is stretching the muscle on the top of your thigh which is called the gastrocnemius.
When the angle of a joint increases, it produces a movement called "extension." This movement typically occurs in joints such as the knee or elbow, where the angle between the two bones becomes larger. Extension is the opposite of flexion, which decreases the angle between the bones at a joint.
The primary function of the knee extension muscle is to straighten the leg by extending the knee joint.
extension
To increase the angle of a joint is extension. To decrease the angle of a joint is flexion. (plato users the answer is A.)
By tensing.
The latissimus dorsi muscle is responsible for adducting the shoulder and causing extension of the shoulder joint. It is a large triangular muscle located in the back that helps with various movements of the shoulder and arm.
when u flex it, it tightens, when u extend it, it stretches Flexion is when a muscle action decreases the angle at a joint, extension is when the angle increases. A simple example is bicep curl, flexion is when the hand is brought up towards the shoulder, decreasing the angle at the elbow joint. Just because a muscle is performing flexion or extension does not not mean it is contracting or stretching, that is eccentric and concentric movement. A muscle can still be tight when performing extension.
To extend a muscle A MOTION IS MADE TO INCREASE AN ANGLE BETWEEN TWO BONES.
