Our shoulders allow us to do so many things with our arms. Your ability to reach up or out in front of your body is because of your shoulders. You couldn’t scratch your nose or feed yourself if you didn’t have shoulders to give you movement.
The deltoid is a large and strong muscle. It is further divided into three parts that we will learn more about next.

Posterior Deltoid
The posterior deltoid (L. posterior, behind; deltoids, triangular) refers to the rear head of the three-headed deltoid muscle. It acts on the shoulder joint and is the prime mover in shoulder horizontal abduction.
Middle Deltoid
The Deltoid muscle (derived its name from the Greek letter delta) is a large, triangular muscle occupying the upper arm and the shoulder giving it this rounded shape. The deltoid consists of three sets of fibers: anterior, middle, and posterior.
