There are many arm muscles. The triceps (on the back of your upper-arm) contract when you straighten your arm, and the biceps (the front of the upper-arm) relaxes.
The biceps brachii muscle will contract, pulling the lower arm up.

The upper arm is part of an arm and therefore there are no complete arms in the upper arm.
