Forensic anthropology  Week 2/22/16  Introduction to Skeletal Biology    Bone  ● Hardness and resilience  ● Tensile strength of cast iron without the weight and density  ● Flexibility of steel   ● Inorganic components  ○ Calcium, phosphorus, magnesium, iron, sodium, potassium  ● Organic components  ○ Collagen fibers    Functions  ● Bony framework  ● Protects vital organs  ○ Eye sockets = eyes protected   ■ Not all animals have eye sockets  ● Provide levers that transmit muscular forces  ● Produce RBC’s  ● Calcium and phosphorus bank    External Structure  ● Periosteum   ○ A membrane that surrounds the bone, that lays over the surface of a live bone  ● Diaphysis  ○ shaft  ● Epiphyses  ○ Bony caps on both ends (growth plates)  ● Metaphysis  ○ In life, thin layer of cartilage in between the epiphyses and diaphysis (the true  growth plates where growth occurs)   ○ The metaphysis calcifies and then adds more cartilage to it  ○ Maturity of different bones fuse together happens at different times    Internal Structure  ● Compact bone  ○ Thick cortex of bone  ○ Variable in width  ○ In long bones, cortex forms a tube surrounding a hollow auxiliary cavity   ■ Lined with endosteum  ○ Cancellous (spongy) bone  ■ Latticework strands of bone  ● Trabeculae    Forensic anthropology  Week 2/22/16  Microscopic Structure  ● Osteon  ○ Haversian System  ● Transmit blood vessels and nerves  ● Lie along lines of mechanical stress  ○ Wolff’s law  ■ More osteons can be laid down where you get more stress  ● Weight Bearing exercise      Bone Cell Functions  ● Produce protein in bone  ● Stimulate mineralization of protein matrix  ● Maintain bone tissues  ● Resorb bone  ○ Eat away at the cell to release what they’re holding  ● Role in mineral physiology  ● Modeling  ○ Bone cells size and shape fetal and subadult skeleton through to maturity  ● Remodeling  ○ Ongoing event separate from growth and development  ○ In adult skeleton the density, shape, and size change in response to factors  ■ Ageing, exercise, injury, trauma, disease, diet, and occupation stress    Osteoblast  ● Bone producing cells  ● Small, single nucleated cells  ● Produce protein matrix called osteoid    Osteocytes  ● Bone maintaining cells  ● Osteoblast that become surrounded by and incorporated with the protein matrix  ○ Means they’re doing their job well    Osteoclasts  ● Large, multinucleated cells  ● Associated with the destruction of bone  ○ Remodel bone  ○ Releasing the minerals within the cell    Apatite  ● Calcium phosphate present in the tissue fluid  ● Crystallizes around the collagen fibers forming the hard matrix of bone    Forensic anthropology  Week 2/22/16  Bone Growth  ● Endochondral Bone  ○ Cartilage model that is gradually replaced by bone  ○ Bones of limbs and vertebral column  ● Intramembranous bone  ○ Thick membrane that gradually mineralized  ○ Flat bones of the skull, mandible and clavicles    Bone Physiology    Calcium  ● Approx 1.5% of body weight  ● Role in blood coagulation, cardiac and skeletal muscle contraction and nerve function  ● 30% decrease in body fluids causes central peripheral nerves to discharge  spontaneously  ● Above normal levels causes depressed reflexes and sluggish CNS  ● 100% turnover each year in infants and 18% turnover in adults  ○ Adults every 5 years have a new skeleton    Phosphorus  ● Required for nucleic acids and phospholipids    Vitamin D  ● Required for absorption of calcium by the gastrointestinal tract and transport of calcium  and phosphate in body  ● Lack produces rickets in children and osteomalacia in adults  ○ Rickets­ bows out the legs  ○ Osteomalacia­ fracture of bones     Human, Nonhuman and Non­Forensic Bone     Human vs Animal  ● Examine gross morphology  ○ Cranial bones fairly easy to distinguish, although immature animal fragments may  appear similar   ○ Teeth fairly easy to distinguish; worn pig molars may cause a problem  ○ Pelvis easily distinguish
