Document Summary
L 11 differentiating human and non human remains. 25-30% cases brought to fas are not humans. Architecture (morphology; how the bone is actually shaped) Poorly defined boundaries between cortical and cancellous bone. Humans have thinner cortical walls; clear transition to cancellous bone. Medullary cavity- houses bone marrow, humans have rounded shaped. Plexiform: horizontal, regular, rectangular organization of cortical bone: humans do not have plexiform. Haversian system (also present in some animals) o o. Fetal remains mistaken for animal remains bc they"re unfused. All mammals have same bones but in different configurations. Human bones shaped differently than non human bones. Bones specialized for bipedal stance: obligate biped. Human: vertebrae increase in size from cranial to caudal o o. Non human: vertebrae same size o o. Some animals have sternal ribs, humans do not. Number of ribs corresponds to number of thoracic vertebra. Look for differences in shaped which are usually related to ways animals use their muscles and bones.
