flexion and extension
Flexion is the movement that decreases the angle between two body parts, such as bending the elbow or knee. Extension is the movement that increases the angle between two body parts, such as straightening the elbow or knee. These actions are essential for joint mobility and allow us to perform various movements.
The elbow can rotate on one plane, allowing flexion and extension movements. The knee can also rotate on one plane, enabling flexion and extension, as well as a slight degree of internal and external rotation.
When you bend your elbow, it makes a flexion movement, bringing your hand towards your shoulder.
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.
Though flexion and extension can occur in a variety of planes depending on the body's position, if you have a body in anatomical position, then all flexion and extension occurs on the sagittal plane.
Muscles within the brachium are responsible for the extension of the elbow. These muscles also work for the flexing of the arm as well.

During a push-up, the elbow joint will mainly undergo extension as the arms straighten to push the body up. This motion is controlled by the triceps brachii muscles on the back of the upper arm.

Elbow injuries while weight-lifting usually occur if you hyper-extend your elbow during dumbbell reps. Hyper-extension of the elbow is when you stretch your elbow joint beyond it's normal range of motion (Eg, moving your elbow all the way down on a dumbbell curl). To counteract it, just bend your elbows inward slightly while lifting. After you've already sustained an elbow injury, rest it for a few days before you weight train again.
