What is the relationship between flexor and extensor?
The key difference between flexor and extensor muscles is that flexor muscles facilitate the process of flexion in the body, while extensor muscles facilitate the process of extension in the body. Flexion is a bending movement where the angle between two body parts decreases.
How do flexor and extensor muscles work together?
Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. Then, when the movement is completed, the flexor relaxes and the extensor contracts to extend or straighten the limb at the same joint.
What is a flexor and extensor muscle?
The opposing muscle of a flexor is called the “extensor” muscle. Your triceps is an extensor. When you contract your triceps your arm straightens and the angle between the forearm and the upper arm increases.
What is an example of a pair of muscles that work together?
One muscle of the pair contracts to move the body part, the other muscle in the pair then contracts to return the body part back to the original position….Antagonistic muscle pairs.
| Biceps | Triceps |

| Hamstrings | Quadriceps |
| Gluteus maximus | Hip flexors |
| Gastrocnemius | Tibialis anterior |
| Pectoralis major | Latissimus dorsi |
What is the function of flexor and extensor?
Flexors and Extensors: What Make Them Skeletal Muscles Flexors and extensors are at the core of this. Together, they bend and straighten the body’s joints to create motion and activate other muscle groups, generating muscle activity — which is another way to say working out.
What action does flexors have?
flexor muscle, any of the muscles that decrease the angle between bones on two sides of a joint, as in bending the elbow or knee. Several of the muscles of the hands and feet are named for this function.
Are hamstrings extensors and flexors?
Hamstrings. The semitendinosus, semimembranosus, and biceps femoris (long and short heads) make up the hamstring group (Fig. Spanning the posterior thigh, the hamstring muscles are the primary knee flexors.
What is the role of the flexor muscle?
What type of muscles are flex-or and extensors?
Extensor carpi radialis longus.
What is the difference between flexor and extensor?
As nouns the difference between flexor and extensor. is that flexor is (anatomy) a muscle whose contraction acts to bend a joint or limb while extensor is (anatomy) a muscle whose contraction extends or straightens a limb or body part.
Are flexors stronger than extensors?
Tendons which straighten joints are called extensors. Flexors are stronger than extensors because they need to generate enough power to grip objects tightly, where as extensors only need enough power to act against gravity and open the fingers up.
What muscle is the strongest flexor of the elbow?
The biceps brachii, a two-headed muscle, sits on the front of your upper arm and is the most visible elbow flexor. It originates on the scapula, runs the length of your upper arm and attaches to the bones of the forearm, the ulna and radius.
