Flexors decrease the angles . Extensorsincrease the angles.
Flexion decreases the angle between two bones in a joint. Extension increases that angle.
Flexion is the general term for movements that decrease the angle between two bones; however, in the sagittal plane, the special term "adduction" is used for movements that decrease the angle between the limb and the midline.
Isometric contraction is a type of muscle movement that does not result in any change in the angle between bones. This type of contraction involves the muscle producing force without changing its length or causing movement at a joint.
When you straighten your fingers out, you are extending them. Flexing refers to bending the joints to decrease the angle between bones, while extending refers to straightening the joints to increase the angle between the bones.
Concentric muscle contraction will shorten a muscle and decrease the angle between two bones. This type of contraction involves the muscle generating force as it shortens to move a body part.
The muscles that contract to bring two bones closer together are called flexor muscles. These muscles work by decreasing the angle between the two bones, resulting in movement such as bending the arm or leg.
Flexion is movement during which the knees or elbows are bent to decrease the angle of the joint
muscles help bones move or do anything
Muscles are attached to two different bones. When a muscle contracts, it shortens. When it shortens, the shortens the angle between the two bones causing movement.
Muscles that increase the angle at a joint are called extensor muscles. When these muscles contract, they pull the bones apart at the joint, resulting in an extension movement. For example, the triceps muscle extends the elbow, increasing the angle between the forearm and the upper arm. This action is crucial for various movements, such as straightening the arm.
muscles move but bones do not
The term for the connection between bones and muscles is called the musculoskeletal junction.
