In my particular case I am able to straighten my arm short of about 5 degrees to what it used to do and short of about 10 degrees when I try the other way that is I just miss out on being able to put my right hand on my right shoulder. I had the elbow replacement done about a year ago.
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.
Flexion causes the angle of the elbow to decrease because you are moving your forearm closer to your bisep therefore the angle decreses. Extension is making the angle bigger for example, straightening you arm, you are extending your arm so that is where the term comes from
flexion and extension
The elbow joint has a humeroulnar and humeroradial joint. The humeroulnar joint allows flexion and extension movements, while the humeroradial joint allows for pronation and supination movements.
Extension. Extension increases an angle, as in straightening a joint. During extension, the knee or elbow are straightened.
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 straightening of a joint so that the angle between bones increases is known as extension. This movement typically occurs in hinge joints, such as the elbow and knee, where the limb straightens out. Extension is the opposite of flexion, which decreases the angle between the bones at a joint.
Flexion causes the angle of the elbow to decrease because you are moving your forearm closer to your bisep therefore the angle decreses. Extension is making the angle bigger for example, straightening you arm, you are extending your arm so that is where the term comes from
The opposite action of flexion is extension. While flexion involves decreasing the angle between two body parts, such as bending a joint, extension involves increasing that angle, effectively straightening the joint. For example, bending the elbow is flexion, while straightening it is extension.

Flexion and extension
The motion of joints, like the elbow, involves flexion and extension, similar to how a door hinge moves. When you bend your elbow, it flexes, decreasing the angle between your forearm and upper arm. When you straighten it, it extends, increasing the angle. Both movements involve the rotation of the joint.
The elbow joint has a humeroulnar and humeroradial joint. The humeroulnar joint allows flexion and extension movements, while the humeroradial joint allows for pronation and supination movements.
Flexion decreases the angle between two bones in a joint. Extension increases that angle.
To increase the angle of a joint is extension. To decrease the angle of a joint is flexion. (plato users the answer is A.)
extension
Elbow joint consists of three joints:Joint between trochlea of Humerus and Ulna is hinge joint (ginglymus joint).Joint between capitulum of humerus and head of radius is also a hinge joint.Joint between Upper ends of radius and ulna is pivot joint.
