16
Q

Origin of the Trapezius muscle

A

Medial 3rd of the Super nuchal line of occipital bone

Ligamentum nuchae

External occipital protuberance

Spinous processes of C7 and all 12 of thoracic vertebrae

17
Q

Insertion of Trapezius muscle

A

Superior:
Clavicle (Posterior lateral 3rd)

Middle: Acromion (medial margin)
              Scapular spine (posterior)

Inferior: scapular spine (aponeurosis)

18
Q

What is the innervation of the Trapezius

A

Cervical nerve XI
(Accessory nerve)

Proprioceptor nerves C3,C4

19
Q

Blood supply of Trapezius muscle

A

Superficial cervical artery

20
Q

Actions of Trapezius

A

Acts on SCAPULA

  • rotation
  • retraction
  • elevation
  • depression
21
Q

Origin of latissimus Dorsi

A

Broad aponeurosis of Posterior layer of thoracolumbar fascia

Lower 6 thoracic vertebrae

Iliac crest

Caudal 3 or 4 ribs

22
Q

Insertion of latissimus dorsi

A

Converges at lower border of teres major, ends as a tendon inserting into the inter-tubercular groove of humerus

23
Q

Innervation of latissimus dorsi

A

Thoracodorsal nerve C6-8

24
Q

Blood supply of latissimus dorsi

A 
Thoracodorsal artery 
(Branch of subscapular artery which arises from axillary artery)
25
Q

Action of latissimus dorsi

A

HUMERUS

  • extends
  • adducts
  • medially rotates
26
Q

Origin of levator scapulae muscle

A

Transverse process of the 1st 4 cervical vertebrae

27
Q

Insertion of levator scapulae

A

Scapula (superior medial border)

28
Q

Action of levator scapulae

A

Scapula

  • elevates superior angle and draws it medically
  • rotates so glenoid cavity is tilted inferiorly
  • when scapula fixed, bends neck laterally and rotates it slightly toward the same side
29
Q

Innervation of levator scapulae

A

C3
C4
-Branch from dorsal scapular nerve C5

30
Q

Origin Deltoid

A
  • Clavicle (lateral 3rd)
  • Acromion (superior surface)
  • spine of scapula
31
Q

Insertion of deltoid

A

Fibres converge into a thick tendon attached to deltoid tuberosity (lateral aspect of the shaft of the humerus)

32
Q

Innervation of deltoid

A

Axillary nerve C5,C6

33
Q

Blood supply of deltoid

A

Thoraco-acromial artery

Anterior+posterior humeral circumflex arteries
Axillary artery

34
Q

Origin of Supraspinatus

A

Occupies supraspinous fossa

Arises from strong supraspinous fascia

35
Q

Insertion of supraspinatus

A

Greater tubercle of humerus (Converge to form tendon)

36
Q

Innervation of supraspinatus

A

Suprascapular nerve

C5 C6

37
Q

Action of supraspinatus

A

Strengthens shoulder joint by drawing humerus towards glenoid fossa

With help from deltoid initiates abduction and Lateral rotator of humerus
