ANT214H5 Lecture Notes - Lecture 6: Collagen, Trace Element, Trabecula
Document Summary
Study of bone/tissue abnormalities in the past. Identity disease process: evaluate frequency, origin and evolution of disease, pathological conditions and environment, nutrition, and culture, evaluate stresses on past populations and ability to adapt. Overall effects of: food available food utilized cultural practices affecting preparation: distribution of food to members of group consumption of food. Reduced adult stature: enamel hypoplasia, harris lines, vitamin/mineral deficiencies, osteoporosis, dental caries, osteoarthritis. Protein energy malnutrition: primary effect slow rate and amount of skeletal growth. Compare aspects of skeletal maturation: appearance/fusion of ossification centres, length of diaphysis, formation and eruption of teeth. Compare stature of adult skeletons to that attained by modern, well-nourished populations. Permanent record of growth disturbances during years of enamel formation: birth 13 years. X-ray: bands of increased radiopacity, trabeculae oriented. Trabeculae oriented perpendicular to cartilaginous surface of growing bone: higher mineral density than rest of bone, occur as growth is resumed.
