  8. Question • Once the bones have been determined to be human, what is the next question the forensic anthropologist must answer?

  9. Answer • Are the remains from a male or a female?

  10. Question • Once gender has been established, what is the next question that a forensic anthropologist must answer?

  11. Answer • How old was the person when he/she died?

  12. Question • Once gender and age have been established, what come next?

  13. Answer • Race, followed by height.

  14. Questions • How many bones does an infant have? An adult?

  15. Answer • Infants have 300 bones while adults have 206.

  16. Question • True or False – The bones of a six year old boy look the same as those of a six year old girl.

  17. Answer • For the most part, yes. The skeletons of adolescents are practically the same until they reach puberty.

  18. Question • True or False – It is easier to determine the age of an adolescent compared to the age of an adult.

  19. Answer • True.

  20. Question • A person’s diet could be determined by examining his/her bones.

  21. Answer • True. One way is by carbon isotope analysis.

  22. Question • What is the most important bone in determining the gender?

  23. Answer • The pelvis.

  24. Question • What are some of the main differences between the male and female pelvis?

  25. Answer • The male pelvic bone forms an angle of less than 90 degrees, while the female’s is larger than 90 degrees. • The sciatic notch on a male is smaller than the sciatic notch on a female.

  26. Question • What is the “wiggle test”?

  27. Answer • When determining gender, the forensic anthropologist will insert his/her finger into the sciatic notch. If the finger can wiggle, then it is a female, if there is not much wiggle room then it is a male.

  28. Question • What is the second most important bone in determining gender?

  29. Answer • The skull

  30. Question • What are the differences between a male and a female skull?

  31. Answer • The bones located above the eyes of the male are more protruded than those of the female. • The bones located below the ear of the male are also more protruded than those of the female. • The occipital protuberance in the male is expressed while in the female it is not. (guys have a little notch sticking out of the lower back of their heads while gals do not)

  35. Answer • The skull, more specifically the maxillary bone.

  36. Question • How does the shape of the maxillary bone differ with the different races?

  37. Answer • Caucasoid – have parabolic shape • Mongoloid – have a rounded shape • Negroid – have a hyperbolic shape

  38. Question • After the bones in the skull, what is the next important bone in the body for determining race?

  39. Answer • The femur. It is used to rule out negroid and caucasoid.

  40. Question • Besides, the bones in the skull and the femur, what other bones are used to determine race?

  41. Answer • The bones of the pelvis.

  42. Question • Identify three bones that are used for determining height.

  43. Answer • The humerus, the femur and the radius. • The femur is the most important. It is approximately ¼ the height of a person. (yes, you need to know this)
