![]() ![]() 1 There are 206 bones (some say 213 4 ) in the human body. ![]() Read more about scientific advances and what questions the bone detectives of the future will ask. Bones can react and respond to environmental stimuli they can get bigger or smaller, they can strengthen themselves when needed, and, when broken, they are among the few organs with the ability to regenerate without scar. ![]() In a forensic or archaeological investigation, a bone biography along with evidence at the scene can answer many questions about an unidentified person.Įven after fingerprints and facial features are gone or unrecognizable, skeletal evidence can tell us: Who was this? What did she look like? What did he do? And maybe how did she die?īecause of changes in diet, activities, medical care and resultant longevity, the bones of individuals today are markedly different from those of the 17th and 18th century - the time of early colonial America. How does the structure of compact bone differ from the structure of spongy bone Explain how the structures of long bones, short bones. The biological profile of every skeleton is unique. Describe the anatomy of the long bone and flat bone. Some of it - height, age, diet, illness, injury - varies over the course of a life. Some of the evidence in bone - sex, ancestry, and genetic makeup - is fixed. These are derived by two distinct types of development: intramembranous and endochondral, respectively, although the development and growth of long bones actually involve both cellular processes. But, between the young and old, male and female, and among ancestral groups, there are recognizable skeletal variations.īones contain a lifetime of personal information. Two types of bones are found in the skeleton: flat bones (skull bones, scapula, mandible, and ileum) and long bones (tibia, femur, humerus, etc.). All of us have the same basic skeletal structures (206 bones in the adult skeleton) that identify us as human. ![]()
