what 4 things do we want to know about a skeleton
-sex
-height
-age
-biological ancestor
teeth are
most useful for developing a profile of a person
to determine sex u examine
the skull, pelvis, humerus and femur
to determine age and height u examine
teeth, bone growth, cranial structure and length of femur bones
to determine race u examine
the skull
ct scan
visualizes internal
x-ray
visualizes bone structure
mass spectrometer
trace elements, health
scanning electron microscope
see very small details
dna analysis
samples of bones
bone is made up of
calcium
things that can be mistaken for bone:
wood, metals, sheetrock, plaster
how to tell if something is a bone
shape, structure, texture, chemical composition
the human body is very
