Learn the muscles of the arm with quizzes, diagrams and worksheets
It is thanks to our arm muscles that we can produce movements of the forearm like flexion and extension. In other words, they play a rather important role in several of our daily movements like brushing our teeth, getting dressed, lifting at the gym and hugging our friends and family.
But most importantly, they’re a topic you simply can’t escape from in your anatomy exam! That’s why, in the following article, we’ll be helping you to learn the five muscles of the arm as quickly and effectively as possible. We'll also be covering the muscles of the shoulder, which are closely related.

Muscles of the upper arm and shoulder
When we speak about the arm, we refer to the portion between the elbow and shoulder joints. Here we find five muscles known as the biceps brachii, brachialis, coracobrachialis, triceps brachii and anconeus.
The former three occupy the anterior compartment of the arm, and are involved in forearm flexion. Conversely the triceps brachii, located in the posterior compartment of the arm, is primarily involved in forearm extension. The tiny but mighty anconeus, although not physically situated on the arm proper, performs a similar function to the triceps.
As the intrinsic muscles of the shoulder attach on the humerus (the only bone of the upper arm), they are often learned alongside the arm muscles. There are six of them in total - the deltoid and teres major, plus the supraspinatus, infraspinatus, subscapularis and teres minor which belong to a group called the rotator cuff.
So now you know the anatomy of the shoulder and arm muscles, right? Wrong! There’s still a lot to learn, including their functions and surrounding structures like blood vessels and nerves. Watching our comprehensive video below is a good place to get started.
In the next section we’ll start the revision process with a handy arm muscle diagram.
Shoulder and arm muscle diagrams
As you’ll know if you’re a fan of our quiz revision series, we always recommend starting revision with a practice test to gauge how much you’ve understood from the video. In today’s case, our tool of choice is a diagram with the arm muscles clearly labeled.
Seeing all of the muscles together in one diagram is a great way to train your brain to differentiate between all of the different structures so you don’t get them jumbled up later down the line. Not to mention, it helps you memorize their long and complicated names!
Labeled arm and shoulder muscles
Take some time to study the arm and shoulder muscles diagram above and connect the different structures with what you’ve learned about their functions in the video.
