Presentation transcript:

Forensic Anthropology A specialty that is concerned primarily with the identification and examination of human skeletal remains

Human Anatomy 1. 206 bone 2. Types of bones: long flat irregular short 3. Are organs with a specific structural arrangement. 4. Internal structure compact bone tissue spongy bone tissue

Internal structure spongy bone tissue “lattice-like structure in spongy bone is called trabeculae.

Race Gender Appropriate age Height What can bones tell us? Which bones tell us this? Skull Race Gender Appropriate age Height Skull, Pelvis Skull, Long Bones Long Bones, Vertebral column Any Bone Previous Trauma

Determination of Sex Supraorbital ridges Zygomatic arch Chin Mandible Occipital protuberance

Name these Bones

Anatomy of the Pelvis

Are We Different?

Determination of Sex: Pelvis Illustrated here are just three of the many differences exhibited between the male and female pelvis. (a) Sciatic notch – females broader than males (b) Preauricular sulci (c) Auricular surface – males flat; females elelvated

Determination of Sex: Femur

Determining Age: Long Bone Epiphyseal Line Growth Plate

More Bone Info Suture Obliteration 60+ adult Suture Obliteration in 60+ years Suture Obliteration 60+ adult

Determining Age: Vertebra

Determining Age: Dentition

Osteometric Calculation Oseteometric Calculation Board Measure the length of the bone from end to end. Use to calculate the height of a person using a devised formula.

Facts about Height Femur = 27% of total height Tibia = 22% of total height Spine = 35% of total height Formulas: l of femur x 2.38 + 61.41 l of tibia x 2.52 + 78.62 l of fibula x 2.68 + 71.78
