1 Anatomy of Bones From Head to toes to hands

2 Vocabulary Medial Lateral Anterior Posterior Superior Inferior Proximal Distal Dorsal/dorsum Palmar Plantar Condyle/epicondyle Fossa Process Tuberosity Styloid Apophysis Diaphysis Epiphysis Medullary cavity Osteoblasts Osteoclasts Periosteum Endoosteum Articular Cartilage/Hyaline Osteocytes Cancellous Bone Wolff’s Law

3 Function of Bone 1. Body support 2. Organ protection 3. Movement (through joints and levers) 4. Calcium storage 5. Formation of blood cells (hematopoesis)

4 Types of Bone Flat- skull, ribs, scapula Irregular- vertebral column, skull Short – wrist and ankle Long- humerus, ulna, radius, femur, tibia, fibula, phalanges, metqacarpal/metatarsal

5 How the bone works You can see: Diaphysis, epiphysis, articular cartilage, periosteum, medullary cavity, & endosteum The end of bones have a layer of hyaline cartilage that provide a very smooth surface that protects and cushions blows to the joint. Periosteum: Covers long bones Sharpey’s fibers connect the periosteum to underlying bone Muscle/tendon fibers interlace the periosteum

6 Bone Growth Bone ossification occurs by the synthesis of osteoblasts Osteoblasts builds new bone on the outside of the bone Same time osteoclsts increase the medullary cavity by breaking down bony tissue. Osteogenesis occurs when there is a balance of bone formation and bone destruction

7 Bone Trauma Periostitis Bone fractures Depressed fx Greenstick fracture Impacted fracture Longitudinal fracture Spiral fracture Oblique fracture Serrated fracture Transverse Fx Communited Fx Contrecoup Fx Blowout Fx Avulsion Fx Stress Fx. Epiphyseal Fx: Salter-Harris Type I-V

8 Anatomy Of The Elbow/Wrist/Hand X 1. Navicular (scaphoid) X 2. Lunate X 3. Triquetral X 4. Pisiform X 5. Hamate X 6. Capitate X 7. Trapezoid X 8. Trapezium X 9. Ulnar styloid X 10. Radial Styloid X 11. Distal/middle /proximal phalanx X 12 DIP, PIP, MCP joints

9 Anatomy Of The Elbow 1. Humeral Shaft. 2. Radial Shaft. 3. Ulnar Shaft. 4. Olecranon Process. 5. Head of the Radius. 6. Coronoid Process of the Ulna. 7. Medial Supracondylar ridge.
