2. Pectoral Girdle Clavicle – collarbone Scapula – shoulder blades
Anterior attachment (?)
Posterior attachment (?)
Scapula – shoulder blades
Spine – divides posterior surface into 2 sections
Coracoid process (“Corac” = ?) – curves to clavicle
Acromion process – forms tip of shoulder
Glenoid cavity (or fossa) – depression that articulates with head of humerus

3. Upper Limb
Humerus
Radius
Ulna
Carpals
Metacarpals
Phalanges

4. Humerus Head fits into glenoid cavity of scapula
Greater tubercle – lateral process
Lesser tubercle – more anterior process
Intertubercular groove – narrow furrow “between tubercles”
Deltoid tuberosity – v-shaped, rough area where _________ muscles attach to humerus
Olecranon fossa – posterior depression that receives an ulnar process when elbow is straightened
Coronoid fossa – anterior depression that receives a radial process when elbow is bent

5. Radius Shorter bone of lower arm Located on thumb side of arm
Disc-like head articulates with humeru and with radial notch of the ulna (so your arm can rotate)
Radial tuberosity, a process below the head, provides attachment for biceps
Styloid process – at distal end; attachment for wrist ligaments

6. Ulna Longer than radius Overlaps distal end of humerus posteriorly
Proximal end has a wrenchlike opening called the trochlear notch (articulates w/humerus)
Oleacronon process – top process
Coronoid process – bottom process
Radial notch – just below trochlear notch
Head – at distal end; articulates with ulnar notch of radius
Styloid process – attachment for wrist ligaments
