Document Summary

Upper limb (reading materials: chapter 7: pages 182-191; chapter 8: pages 223-228) Bones: (32 bones 64 bones in total) Medial (vertebral) : closest to the spine. Lateral (axillary) : near the region near axilla, armpit: angles (corners of scapulae) : between two borders. Lateral: superior and lateral: anterior (costal) surface: close to ribs. Subscapular fossa: fossa = shallow depression: coracoid process: anterior, medial, posterior surface. Spine: dividing posterior surface into 2 fossae. Acromion process: posterior, lateral expansion of spine. Infraspinous fossa: depression below spine: glenoid fossa: actual articulating surface of scapula. Easy to break here, most common fracture point: shaft (body) : long, has a triangular shape o. Lesser tubercle (medial and anterior) : anterior and medial, smaller bump. Tendon of biceps sits in that groove: radial groove/spiral groove; shallow groove running down humerus, spiraling around the shaft. Radial nerve travels along that groove to provide innervation: mid-shaft:
