Pectoral girdle
Clavicle and scapula
Sternoclavicular joint type
Saddle joint
Sternoclavicular joint function
Articulates with the sternum
Acromioclavicular joint type
Fixed joint
Acromioclavicular joint function
Acromial end of clavicle articulates with the acromion process
Acromion definition
Process where scapula articulates with the acromial end of clavicle
Coracoid process
Muscle (coracobrachialis, etc.) attachment
What do the 3 fossae do?
Houses rotator cuff muscles and stabilizes the glenohumeral joint in the shallow glenoid cavity
What are the 3 fossae?
Supraspinous fossa (posterior, infraspinous fossa (posterior), and subscapular fossa (anterior)
Spine of scapula function
Separates 2 posterior fossa
Glenoid cavity function
Site of articulation with humerus
Protraction of scapula
When you reach forward. Scapula slides laterally and somewhat anteriorly
Retraction of scapula
Occurs when you pull the scapula toward the center of your back
Elevation of scapula
Occurs when shrugging your shoulders, scapula moves superiorly
Depressoin of scapula
Occurs when scapula moves inferiorly
Surgical neck of humerus
Much more commonly fractured and narrower
Anatomical neck of humerus
Epiphyseal plate that separates the head of humerus from diaphysis
Olecranon fossa
Holds the olecranon process of ulna, allowing for full extension of elbow joint
Lateral epicondyle
Attachment point for most posterior forearm muscles
Medial epicondyle
Attachment point for most anterior forearm muscles
