Antemortem Pathology Flashcards
Premortem/antemortem
Occurred before death
Perimortem
Occurred near time of death
Postmortem
Occurred after death
Normal sources of variation
Sex
Age
Ancestry/population
Individual
Anomalies
Individual variations outside of “normal”
Pathologies
Anomalies detrimental to the individual
Pathology
The study of the cause and nature of disease
Proliferative (blastic) response or lesion
Deposit new bone
Lytic response or lesion
Destroy or resorb bone
Deformative response or lesion
Shape changes- destroy and/or deposit new bone
Lytic lesions
Anemic conditions
Necrosis: bone tissue death
Abscesses
Amputations
Proliferative lesions
Osteophytes Callus around healed trauma Bone tumors Diffuse idiopathic skeletal hypertosis (DISH) Osteitis: bone infections
Deformative lesions
Wedging
Osteomalacia
Kyphosis
Scoliosis
Achondroplasia
Endochondral growth ceases early
Dwarfism
Gigantism
Childhood more proportional growth
Acromegaly
Post epiphyses union, mandibular condyle particularly effected
Dental pathologies
Caries Dental calculus Periodontal disease Abscesses Enamel hyperplasia
Skeletal anomalies: non-fusion
- metopism
- Spopndylolysis
- spina bifida
Skeletal anomalies: accessory bones
- Wormian bones (bregma and Inca bones)
- supernumerary elements (vertebrae, ribs, digits, teeth)
Pseudarthrosis
- false joint skeletal anomaly
- often result of traumatic injury
Harris lines
- reduced bone growth and bands on bone that are result of malnutrition
- marks time period for when malnutrition occurred during development
