FILL IN THE BLANK (2 points each) Fill in the blanks using the following terms. Not all choices will be used. No choice will be used more than once.

  2. The __ ZYGOMATIC ___ bones are often termed the ‘cheek bones’. They form the lateral walls of the orbits.
  3. The ___ LACRIMAL __ bones are the tiniest bones found in the face. Tiny foramina within the bone allow passage of the tear ducts.
  4. The __ NASAL _ bones form the bridge of the nose.
  5. The external acoustic meati are found within the __ TEMPORAL _ bones.

SHORT ANSWER (2 points each)

  1. Based on what you learned in lecture, and from the Stout chapter in the Steadman text, list two applications of bone histology analysis to a forensic case. (1) Determination if the remains are bones (2) Identification of non-human vs. human remains (3) Age estimation
  2. You are called into the medical examiners office to examine some skeletal remains thought to be of forensic significance. The remains include a complete torso including the sternum, ribs, vertebrae, os coxae and proximal femora. No cranial remains were found. All epiphyses/secondary ossification centers are fused. List four macroscopic methods of adult aging could be applied to this specimen. (1) Morphology of the pubic symphyseal surface (2) Morphology of the Auricular surface of the ilium (3) Morphology of the sternal rib edge (4) Degenerative changes in the vertebrae/proximal femur SHORT ANSWER (4 points)
  3. You are asked by the prosecution in court why you give an age range for an individual rather than a specific age. What is your reason for giving a range, and how broad should that range be? There is inherent variation in the timing of developmental events and degenerative events in the skeleton, both between populations and individual, and within a single individual. Therefore, skeletal aging methods can only provide a range of ages rather than a specific age. Utilization of as many elements/methods may allow you to narrow this age range, but variability in the timing of events must be taken into account in the calculation of the age range (with larger variability the older the individual is). Providing a broad age range lessens the possibility that investigators might mistakenly eliminate individuals from their investigation.
