APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Muscles that work with the deltoid include the supraspinatus, infraspinatus, teres minor, and the subscapularis.

Detailed explanation-2: -The primary muscle group that supports the shoulder joint is the rotator cuff muscles. The four rotator cuff muscles are the supraspinatus, infraspinatus, teres minor, and subscapularis.

Detailed explanation-3: -Your deltoid muscles are in your shoulder, which is the ball-and-socket joint that connects your arm to the trunk of your body. Deltoid muscles help you move your arms in different directions. They also protect and stabilize your shoulder joint.

Detailed explanation-4: -middle deltoid. The middle deltoid is associated with ONLY shoulder abduction. The deltoid originates from three different heads (points) which are anteriorly, posteriorly and laterally.

Detailed explanation-5: -The deltoid muscle has been classically divided into three anatomical portions: the anterior; the middle; and the posterior portions.
