How do skeletal muscles work as a pair to bend and straighten the arm at the elbow?
When you bend your elbow, the biceps muscle contracts. At the same time the antagonist muscle, that is the triceps muscle relaxes in synchronized manner. Vise verse action take place, when you straighten the arm at the elbow. Triceps contracts and biceps relaxes.
What happens to your biceps muscle when you straighten your elbow?

What is the difference between brachialis and brachioradialis?
The brachialis muscle is located deep to the biceps brachii and is the main flexor of the elbow joint. The brachioradialis muscle is a superficial muscle located on the lateral side of the forearm that aids in both elbow flexion and forearm supination.
Antagonist of brachialis?
The primary antagonist of the brachialis muscle is the triceps brachii muscle. When the brachialis contracts to flex the elbow, the triceps relaxes to allow this movement.
Is biceps and triceps are exampes of skeletal muscles?
Yes they are. The Bicep muscle is attached to the humerus bone (upper arm) at the front. It's the muscle that contracts when you want to bend your arm at the elbow. The tricep muscle is attached to the same bone - but runs down the back. It straightens your arm when it contracts.
