Pictured above is the triceps muscle. It straightens your elbow and pulls your arm toward your side. The long head of your triceps attaches to both your elbow and your shoulder blade, and can keep you from easily being able to raise your arm overhead when it gets too tight. Issues like tennis elbow respond well when you reduce excess tension in the triceps.
The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.
Click here for a list of all the muscles.
The following muscles attach across the elbow joint, to the upper arm (humerus) & the arm (radius or ulna), or to the arm & the wrist/hand (one or more of the numerous bones in the wrist & hand). Click the appropriate link for your interest. (any inactive links will be live soon)
