Final answer:
The superficial anterior muscles that move the upper limb are comprised of the pectoralis major, deltoids, latissimus dorsi, subscapularis, supraspinatus, infraspinatus, and teres minor, which are responsible for various motions including flexion, extension, and rotation of the arm.
Step-by-step explanation:
Superficial Anterior Muscles that Move the Upper Limb
The superficial anterior muscles that move the upper limb include several key groups that contribute to the movements of the forearm, arm, and the pectoral girdle. When labeling these muscles, we focus on the pectoralis major, which originates from the sternum and attaches to the humerus, facilitating anterior movement of the arm. Additionally, the deltoids, which originate from the clavicle and scapula, move the arm superiorly. The latissimus dorsi, originating from the back, moves the arm inferiorly. The strong subscapularis and the supraspinatus aid in medially rotating and abducting the arm, respectively, while the infraspinatus and teres minor are involved in lateral rotation.
It is important to also mention the role of the muscles in the anterior compartment of the forearm, such as the flexor carpi radialis and palmaris longus, which play a significant role in moving the wrists, hands, and fingers. Altogether, understanding these muscle groups and their functions aids in analyzing how these movements are performed and how they are integral to upper limb mobility.
