  2. 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

  3. 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 The muscles of Shoulder girdle: Those attached to the Scapula 10 muscles arise from scapulae and inserted to humerus:

  4. The muscles of Shoulder girdle: Those attached to the Clavicle • There are 5 muscles attached to the clavicle as the following: • 1- Trapezius • 2- Subclavious • 3- Pectoralis major • 4- Deltoid 2 muscles arise from axial skeleton and inserted to the clavicle: 2 muscles arise from the clavicle and inserted to Humerus: 1 muscles arise from the clavicle and inserted to axial skeleton, Sternocleidomastoid

  5. Insertions: 1- Supraspinatus 2- Infraspinatus 3- Teres minor 4- Pectoralis major 5- Teres major 6- Latissimus dorsi 7- Subscapularis 8- Deltoid 9- Coracobrachialis Origins: 1- Triceps (lateral head & medial head 2- Brachioradialis 3- Brachialis 4- Pronator teres 5- Extensor carpi radialis L 6- Anconeus 7- Supinator 8- Common origin of forearm flexor muscles (PT, PL, FCR, FCU, FDS) 9- Common origin of forearm extensor muscles (ECRB, ED, EDM, ECU) The muscles attached to the Humerus 18 muscles attached to humerus: 9 muscles are inserted from shoulder girdle to humerus upper half 9 muscles take origin from humerus lower half

  6. The muscles Attached to the Radius & Ulna Insertions to Radius: 1- Biceps Brachi 2- Pronator teres 3- Brachioradialis 4- Pronator Quadratus 5- Supinator Origins from Radius 1- Flexor digi super (radial head) 2- Flexor policis longus 3- Abductor policis longus 4- Extensor policis brevis Insertions to The Ulna: 1- Triceps 2- Brachialis 3- Anconeus Origins from The Ulna 1- Flexor Digi superficialis 2- Pronator teres 3- Flexor digi profundus 4- Pronator quadratus 5 -Flexor carpi ulnaris 6- Extensor carpi ulnaris 7- Abductor policis longus 8- extensor policis longus 9- extensor indicis 9 muscles attached to Radius, : 12 muscles attached to the Ulna

  7. The Forearm muscles Attached to:both the Radius and the Ulna 1- Supinator * 2- Flexor Digi superficialis * 3- Pronator teres8* 4- Pronator quadratus 5- Abductor policis longus 6- Flexor policis longus (sometime it has an ulnar head as well) * = Humerus, Radius & Ulnar attachments 6 muscles attached to both Radius and Ulna :

  8. The forearm muscles Attached only to the Radius Insertions to Radius: 1- Biceps Brachi 2- Extensor policis brevis 3- Brachioradialis 2 muscles attached only to Radius, :

  9. 1- Triceps 2- Anconeus 3- Brachialis 4- Extensor Indicis 5- Extensor policis longus 6- A common aponeurosis for FCU, ECU & FDP The forearm muscles Attached only to the Ulna 7muscles attached to Ulna
