Question

lo 5.3. what are the major muscle groups of the upper limbs?
rectus abdominis, obliques, and erector spinae
biceps brachii, triceps brachii, and coracobrachialis.
sartorius, gracilis, and semitendinosus
deltoids, pectorals, and latissimus dorsi
trapezius, teres major, and supraspinatus

Explanation:

The rectus abdominis, obliques, and erector spinae are related to the torso and not upper - limb muscles. Sartorius, gracilis, and semitendinosus are muscles of the lower limb. Deltoids are shoulder muscles, pectorals are chest muscles related to upper - limb movement but latissimus dorsi is more associated with the back and not strictly an upper - limb muscle group. Trapezius is a back and neck muscle, teres major and supraspinatus are shoulder muscles but not as representative as the biceps brachii, triceps brachii, and coracobrachialis which are directly in the upper - arm part of the upper limbs.

Answer:

B. Biceps brachii, triceps brachii, and coracobrachialis
