What is the elbow joint?
The elbow is the joint that connects your upper arm to your forearm.
Like all your joints, your elbows are part of your skeletal system. Your elbows also contain cartilage, muscles, ligaments, nerves and blood vessels.
Visit a healthcare provider if you’re experiencing elbow pain or other symptoms that make it hard to use your elbow. They’ll diagnose the cause and suggest treatments to help you get back to your usual routine and activities.
What is the function of the elbow?
Your elbow flexes to bend your arm. It can move in four directions:
Extension : Straightening your arm out further away from your body to reach objects.
Flexion : The opposite of extension — bending in your lower arm toward your body.
Supination : Moving the palm of your hand up.
Pronation: Moving your palm down.
