the deltoid muscle is the principle abductor of the arm but due to poor mechanical advantage it cannot initiate this action; it is assisted by the supraspinatus m. dorsal interosseous (hand) four muscles, each arising from two adjacent metacarpal shafts
muscles are associated with the upper extremity; intermediate muscles are associated with respiration ; deep muscles are associated with movements of the trunk and back (see chart for muscle names, actions and innervation).
PREFACE. The Muscular System Manual: The Skeletal Muscles of the Human Body, 4th edition, is meant to be the most thorough atlas of muscle function that is available. Instead of simply listing muscle attachments and actions that are typically taught, The Muscular System Manual comprehensively covers all muscle functions of each muscle.
