Bones And Joint Shoulder Girlde Flashcards
What are the main bones in the shoulder girdle
Scapula, Clavicle, Humerus
What are the Boney landmarks of the clavicle
Acromial end (flat side) - articulates with the scapula
Sternal end (rounded side) - articulates with the sternum, rests on 1st rib
Conoid tubercle
Trapezoid line
Tubercle, tuberosity, Bump, raised area
This is where muscle is attaching, sometimes a ligament
Facet (smooth)
2 bones set together or rubbing together
What are the landmarks on the dorsal (posterior) side of the Scapula
Spine of the scapula, Supraspinous fossa, Infraspinous fossa
What are the landmarks on the ventral (anterior) side of the Scapula
Subscapular fossa
What are the landmarks on the lateral side of the Scapula
Glenoid cavity, supraglenoid tubercle, infraglenoid tubercle
What makes up the osteology of the Humerus?
Head
Anatomical neck Vs Surgical neck
Greater tubercle ( lots of stability from the rotator cuff muscles)
Lesser tubercle
Inter-tubercular sulcus
Mid-shaft
What are the 3 main joints in the shoulder girdle
Sternoclavicular, acromialclavicular, Glenohumeral
What are the ligaments that make up the Sternoclavicular joint
Anterior and posterior Sternoclavicular ligament
Interclavicular ligament
Costoclavicular ligament
What’s the purpose of the Sternoclavicular joint
What ligaments make up the Acromioclavicular joint
Superior and inferior Acromioclavicular ligament
Coracoclavicular ligament (conoid/ trapezoid)
What kind of joint is the Glenohumeral joint
Ball and socket (tons of movement) / Multiaxial
Little stability from skeleton
What ligaments make up the Glenohumeral joint
Glenohumeral ligament ( superior, middle, inferior)
Coracohumeral ligament ( strengthens the superior part of the capsule)
Transverse humeral ligament
Transverse scapular ligament
