Document Summary
Individuals and their skeletons can be unique and varied due to genetic and environmental influences. Some diseases have similar appearances but different skeletal distributions (or vice versa) Present in (almost) everyone, but with small and significant differences. Paranasal sinus shape: group of 4 paired, air-filled spaces around nasal cavity. Can change in adulthood due to trauma, disease, bone loss . Not necessarily rare or unique, but they"re individualizing features. Persistent metopic suture: suture between 2 frontal bone halves. Supernumerary teeth: hyperdontia = more teeth than "normal" May change the shape of a metatarsal, metacarpal, phalanx. 2-3% missing upper lateral incisors or 2nd premolars. Fibula may not form for be shorter than average. Rare, but the most common absence of long bones. Changes to the skeleton related to habitual or repetitive activity. Pipe smoking, external auditory exostoses, corsetry, bunions and shoes. Pathological condition: usually the result of disease, trauma, or congenital condition. Not all pathological conditions leave marks on bone.
