Which muscles are included in the Superficial Back Arm Net (SBAN)?

• A. Trapezius and latissimus dorsi
• B. Deltoid and extensor myofascial
• C. Levator scapulae and rhomboids
• D. Triceps brachii and biceps brachii

Answer: (B)

The Superficial Back Arm Net (SBAN) primarily consists of the deltoid and extensor myofascial, which play significant roles in connecting the upper limb to the back and ensuring efficient movement and posture. The deltoid, being a major muscle of the shoulder, is responsible for arm abduction, flexion, and extension, while the extensor myofascial refers to the connective tissues associated with the extensor muscles of the arm and forearm that facilitate movement at the elbow and wrist joints. This connectivity through the SBAN contributes to the functionality of both upper limb movements and the stability of the shoulder girdle. Therefore, understanding the role of these muscles and their placement within the SBAN is crucial for grasping how the shoulder and upper back work together in dynamic activities. The other muscle groups mentioned do not accurately represent the composition of the SBAN and instead focus on different muscle functions or regions, which is why they are not included in the correct answer.
