Document Summary
Clavicle connects upper appendicular skeleton to axial (attaches at. Humerus upper arm: two arcs, flat portion is medial, rounded articulates with bone of scapula (acromial end, most commonly broken bone because shoulder is so mobile. Articulates with sternum= sternoclavicular: two tubercles (greater and lesser) attach rotator cuff muscles. In between intertubercular sulcus (groove): passage of bicep tendon and attachment for pec major and minor: deltoid tuberosity: attaches deltoid, radial groove: artery wraps around and break here severs artery, two epicondyle= elbow. Lateral: capitulum: articular surface for radius, trochlea: groove shaped or v shaped, articular surface for ulna. Scapula: medial border, lateral border, superior angle, inferior angle, two bony projections that serve for attachment points. Coracoid process : glenoid cavity: attachment for head of humerus, subscapular fossa on anterior side. Subscapularisis attaches here= rotator cuff muscle: supraspinous fossa, interspinous fossa, separated shoulder: acromial head separates from acromion. Deltoid: origin: clavicle, acromion, spine of scapula, inserts: humerus (deltoid tuberosity, action:
