Function= adducts

18
Q

Deltoid

A

Origin- scapula
Insert- deltoid tuberosity on lateral humerus
Function= flex and extend arm at shoulder

19
Q

Parts of the scapula

A

Anterior:

  • Acronium
  • Corocoid process-0 hook like projection, lies underneath calvicle
  • glenoid process
  • Subscapula fossa- concave

Posterior:

  • Coronoid process
  • Acronium- projection of spine
  • Glenoid process
  • Supraspinatus fossa- smaller and more convex
  • Infraspinatus fossa- convex
20
Q

Lateral surface of the scapula

A

glenoid process- shallow cavity that articulates with the humerus
tuberglenoid tubercle- superior glenoid fossa, attach head of biceps brachii
infraglenoid tubercle- inferior, attach head of triceps brachii

21
Q

Tubercle

A

Where muscle or ligament attaches

22
Q

Articulations of scapula

A
  1. Glenohumeral

2. sternoclavicular

23
Q

Articulations of clavicle

A
  1. Sternoclavicular

2. Acromioclavicular

24
Q

Glenohumeral

A

Head of humerus and glenoid fossa

Movement- axial rotation and anterior/ posterior movement

25
Q

Sternoclavicular

A

Saddle joint between the sternum manibrum and clavicle
Movement:
-Elevates- Shrugging or abducting about 90
-Depression- drooping shoulders and extending arm
- Protraction- anterior shoulder movement
-Retraction- posterior
-Rotation- arm raised over head

26
Q

Glenohumeral joint

A 
Glenoid process and head of humerus 
ball and socket joint 
Movement:
-Extension 
-flexion 
-Abduction- 0-15 
-Adduction
-Medial and lateral rotation
27
Q

Axillar region

A

underneath of the glenohumeral joint at the junction of the upper limb and thorax

28
Q

Clavicle

A

Sternum to scapula

can be palpated

29
Q

Parts of the clavicle

A

Sternal end

  • facet for articulation with manibrum
  • impression of costoclavicular ligament

Acromial end

  • Conoid tubercle- attachment of conoid ligament
  • Trapezoid line- attach trapezoid ligament
30
Q

Humerus parts

A

Proximal

  • Greater tubercle= supraspinatus, infraspinatus and teres minor
  • lesser tubercle= subscapularius
  • Head
  • Interubercular sulcus- groove between tubercles for biceps brachii
