Deltoids, Rhomboids, SCM, Levator Scapulae
Sternocleidomastoid: Origin
-Manubrium of sternum -Superior medial 1/3 of clavicle
Rhomboid Minor: Action
-Scapular Retraction -Scapular elevation -Scapular Downward rotation
Rhomboid Minor: Origin
-Spinous processes of C7-T1
Levator Scapulae: Innervation
-Cervical Spine nerves -dorsal scapular nerve
Rhomboid Major: Innervation
dorsal scapular nerve
Levator Scapulae: Origin
transverse processes of C1-C4
Middle Deltoid: Innervation
Axillary nerve
