Which muscles were used to extend and splay your fingers outward?
The extensor digitorum is the muscle used to extend and splay fingers outward.
Which muscles make your arm extend?
Extension (forearm away from upper arm): Produced by the triceps brachii and anconeus of the forearm. Flexion (forearm towards upper arm): Produced by the brachialis, biceps brachii, and brachioradialis of the forearm.
Which are muscles that extend and/or pronate the arm at the elbow?

The muscles involved in the flexion movement include the anterior deltoid, pectoralis major and coracobrachialis. For a shoulder extension, your body uses the latissimus dorsi, teres major and minor and posterior deltoid muscles.
Why is the top of my arm so painful?
Specific local pain in the upper arm, when you move or lift things, is likely to be muscle or tendon issues. The triceps can have issues like tendonitis, around the insertion point into the elbow, as can the biceps. This can be treated with a combination of shockwave, manual therapy and exercise.
What is the muscle responsible for extension of the forearm at the elbow?
Several muscle groups cross over the elbow joint. The muscles involved in flexion (bending) the elbow are the biceps brachii, brachioradialis and the brachialis. The triceps are responsible for elbow extension (straightening the arm).
Which two main muscles are involved in flexing and extending the arm in elbow?
These include the following: Biceps brachii: upper arm muscle enabling flexion of the arm. Triceps brachii: muscle in the back of the upper arm that extends the arm and fixes the elbow during fine movements. Brachialis: upper arm muscle beneath the biceps which flexes the elbow towards the body.
What is the muscle behind your bicep called?
Brachialis. This muscle lies underneath your biceps. It acts as a bridge between your humerus and ulna, one of the main bones of your forearm. It’s involved with the flexing of your forearm.
