Which Muscles Move the Arm?
Posted on 21st December 2021
As humans, we have over 600 muscles that we rely on each day in order to move freely. There is, however, no singular way of learning them. In the next 3 blogs, we’re going to be looking at an easier way to remember them all.
Today we’re going to be focusing on the muscles that support the movement of the arm, shoulder, elbow, and wrist.
The Shoulder Joint
The shoulder joint (glenohumeral joint) is the attachment of the humerus to the scapula. This is a ball and socket joint, and many actions occur here.
Elbow and Wrist Joint
The elbow joint consists of the humerus, radius, and ulna. The two main actions at this joint are flexion and extension. The wrist joint consists of the distal (bottom) ends of the radius, ulna, and the carpal bones.
The best way to learn the muscles is the move and copy the action that the muscles perform. Try and find a diagram of the body, pinpoint the location of the muscles mentioned above, and then perform the action. Focus on how the muscles contracts and relaxes during the movement.
