Document Summary
Bodily proportions consistent from person to person usually. Predictable relationship between limb length and stature. Trauma and pathology can leave effects on height- acquired and congenital. Age, sex and ancestry can cause variance. Stature increases to adulthood, then decreases with age: not a standardized rate of decrease, vertebral compression and bone diseases results in height loss (loss of vertebral disc space) Sexual dimorphism- males usually taller than females. Must determine sex before stature for accuracy. Human body form consistent with ecological rules by bergmann and allen- clinal distribution. Rules to maintain homeostasis- size correlates to heat regulation; hot climates need more surface area to disperse heat: allen: hot climates have longer appendages, cold climates have shorter appendages o. Bergmann: hot climates=smaller body volume (lean build), cold climates= more volume (stockier build) Based on measuring all skeletal elements, and some selected skeletal elements.
