Learn more about the structure of arm muscle using these printable arm muscles diagrams! A total of five diagrams are provided to show you the anatomy of arm muscles. The following arm muscle diagrams are available to help you understand more about the muscles in our arm. We’ll start by giving you the first labeled arm muscle diagram below.
The arm’s curved shape comes from its major exterior muscles. These bulky muscles also give the arm its strength. You can see in the arm muscle diagram above that there are important parts in arm muscles. The large muscle of the upper arm is formally known as the biceps brachii muscle, and rests on top of the humerus bone. It rotates the forearm and also flexes the elbow. More muscle diagrams are provided below.
Triceps is the large muscle in the back of the upper arm helps straighten the arm. It is formally known as the triceps brachii muscle. Brachioradialis is located at the top of the forearm near the elbow, helps rotate the forearm both outwardly and inwardly. It also flexes the forearm at the elbow. Extensor carpi radialis longus is the muscle next to the brachioradialis is one of five major muscles that help to move the wrist in multiple directions. When you clench your fist, this muscle bulges out from the skin. The deltoid muscle controls the majority of the shoulder’s movements and thus enables the arm to have increased range of motion.
