no attachment to the posterior ribcage; it attaches to the clavicle at the acromioclavicular joint
spans from the occipital portion of the skull to the twelfth thoracic vertebra. The lower portion of the trapezius depresses the scapulae.
levator scapulae muscles
elevate the scapulae
retract the scapulae
serratus anterior muscles
both stabilize and draw the scapulae toward the front of the ribcage
the muscle that makes up the superior portion of the musculotendinous cuff group, from the scapula to the top of the humerus, and which abducts the humerus
muscle that spans across the front of the scapula, from the vertebral border of the scapula to the anterior humerus, and which medially rotates the humerus
muscle that spans from just below the spine of the scapula to the posterior humerus, which laterally rotates the humerus
muscle that spans from the inferior corner of the scapula to the posterior humerus and also laterally rotates the humerus
muscles participate in scapular
(1) trapezius, (2) serratus anterior, (3) pectoralis minor, (4) rhomboid major, (5) rhomboid minor, (6) levator scapulae
