The extension in the elbow occurs when the triceps muscle contracts, causing the forearm to straighten out. This movement is essential when performing actions like pushing and lifting objects.
flexion and extension
These terms used in physiology refer to actions that occur at a joint in the body. Flexion usually refers to the part away from the body being brought toward the midline of the body while extension usually refers to the part away from the body being moved away. As an example when the hand is brought toward the face, flexion occurs at the elbow and when the hand is moved away from the face, extension occurs at the elbow.
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.
Flexion when you pull your forearm towards your body and extension when you extend it away from your body.
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.

flexion and extension
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.
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.
