Pectoral (Shoulder) Girdle consists of: |
2 clavicles 2 scapulae
|
|
Functions of the Pectoral Girdle: |
Supports the upper limbs Serves as attachment for several muscles
Rotator cuff muscles, biceps, deltoids, etc.
|
|
Movements of the Pectoral Girdle: |
Elevation & depression Upward & downward rotation Protraction & retraction |
|
Clavicle: |
Rod like s-shaped bone Most commonly fractured bone in the body First bone to ossify in fetus |
|
Clavicle: (3 portions) |
1. Body 2. Medial (sternal) end: articulates with the manubrium of the sternum
3. Lateral (acromial) end: articulates with acromion process of the scapula |
|
Clavicle: (Functions) |
Braces scapulae to hold shoulder in place Attachment place for muscles |
|
Scapula: |
Protects thoracic vertebrae 1-7 & ribs 2-7 Least fractured bone in the body |
|
