Final answer:
The shoulder muscles are known as deltoids and play a vital role in various arm movements. Key shoulder muscles include pectoralis major, latissimus dorsi, and others. Understanding these muscles is essential for arm and shoulder mobility.
Explanation:
The shoulder muscles are also known as the deltoids. The deltoid muscles are triangular muscles that cover each shoulder, allowing for various arm movements like abduction, flexion, and extension. The deltoids are named after the Greek letter delta due to their triangular shape.
In addition to the deltoids, other important shoulder muscles include the pectoralis major, latissimus dorsi, subscapularis, supraspinatus, infraspinatus, teres major, teres minor, and coracobrachialis. These muscles work together to facilitate different movements of the arm and shoulder joint.
