The muscles of Shoulder girdle: Those attached to the Scapula
•There are 17 muscles attached to the scapula as the following:
–7 muscles inserted to the scapula from axial skeleton:
•1 -Trapezius•2 -Serratus anterior•3 -Levator scapulea
•4 -Rhomboideus minor•5 -Rhomboideus major
•6 -Pectoralis minor•7 -Omohyoid
The muscles of Shoulder girdle: Those attached to the Scapula
–1 -Subscapularis•2 -Supraspinatus
•3 -Infraspinatus•4 -Teres minor•5 -Teres major
•6 -Latissimus dorsi (a small part of that)
•8 -long head of triceps•7 -Deltoid•9 -Biceps
•10 - Coracobrachialis
10 muscles arise from scapulae and inserted to humerus:10 muscles arise from scapulae and inserted to humerus:
