Shoulder Girdle + Shoulder 1 Flashcards
What is the shoulder girdle
Bones, Joits and muscles associated with the attachment of upper limb (arm) to the trunk
What is the shoulder joint
The area of articulation of the upper limb with the shoulder girdle
Three bones in shoulder girdle
Clavicle
Sternum
Scapula
Three joints of shoulder girdle
Acromioclavicular joint
Sternoclavicular joint
Scapula-thoracic Junction
Clavicle function?
Absorb tension and compression stresses allowing transmission of forces from upper limb to trunk
Medial end articulation of clavicle
It articulates with the clavicular notch of the manubrium of the sternum, forming the sternoclavicular joint
Lateral end articulation of clavicle
Acromial facet articulates with the acromion process of the scapula to create acromioclavicular joint
Name these four bony landmarks of the inferior surface of the clavicle
What fossa(s) is on the posterior side of scapula bone
Infraspinous fossa
Supraspinous fossa
What fossa(s) is on the anterior aspect of scapula
Subscapular fossa
What part of scapula articulates with clavicle
Acromion process of the acromion articulates with acromial facet of clavicle to form Acromioclavicular Joint
Three main parts of sternum? (From prox to distal)
Manubrium
Body of sternum
Xiphoid process
