Flexing is the medical term meaning decreasing an angle as in bending a joint.
In medical terms, flexion means decreasing the angle of a joint.
Flexors decrease the angles . Extensorsincrease the angles.
Flexion or extension; flexion is decreasing the angle between two points
To increase the angle of a joint is extension. To decrease the angle of a joint is flexion. (plato users the answer is A.)
A right angle joint is called a vertex as is with any other angle (yes even straight angles)
A flexor is a skeletal muscle whose contraction bends a joint. In anatomy, flexion is a position that is made possible by the joint angle decreasing. The skeletal (bones, cartilage, and ligaments) and muscular (muscles and tendons) systems work together to move the joint into a "flexed" position. ...
Athetosis is involuntary writhing movement at a joint.Torsion is a general technical word for twisting.Sprain is sometimes the result of twisting of a joint.Athetosis
A mitre joint forms a nice right angle.
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.
extension
Flexion is movement during which the knees or elbows are bent to decrease the angle of the joint
