The biceps brachii muscle will contract, pulling the lower arm up.

To raise the lower arm, the muscles in the upper arm, primarily the biceps brachii, must contract. This contraction pulls on the radius bone of the forearm, causing the elbow joint to flex and the lower arm to lift. Additionally, stabilizing muscles in the shoulder and forearm assist in the movement to ensure proper coordination and control.
The upper arm is the humerus, the lower arm is made up of the radius and ulna. The joint connecting the upper is called the humeroulnar joint.
Upper: humerus. Lower: Radius and ulna
Upper arm: Humerus Lower Arm: Ulna & Radius

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 posterior deltoid is one extensor of the upper arm.

Upper arm = Humerus Lower arm = Ulna and Radius
it is called curl
