CFC Forensic Anthropology & Skeletal Analysis 3

Question 1

Perimortem trauma in forensic anthropology refers to injuries that occurred:

Accepted Answer

Around the time of death before significant decomposition or drying

Answer

Long before death, showing complete bone healing and remodeling

Answer

After death when decomposition had advanced significantly

Answer

During embalming or mortuary preparation

Question 2

Postmortem bone damage is distinguished from perimortem trauma primarily by which characteristic?

Accepted Answer

Differences in fracture pattern morphology and color changes from drying and bleaching

Answer

The presence of hemorrhagic staining around the margins

Answer

Greater depth of incised marks on the bone surface

Answer

The presence of embedded projectiles or foreign material

Question 3

Sharp force trauma on bone is most characteristically identified by which feature?

Accepted Answer

Smooth-edged incised marks or saw kerf marks with flat internal walls

Answer

Radiating fracture lines emanating from the impact point

Answer

Depressed, beveled fractures at the site of contact

Answer

Spiral fractures of the long bone diaphysis

Question 4

In blunt force trauma to the skull, a 'pond fracture' specifically refers to:

Accepted Answer

A localized depressed fracture at the impact site where bone is driven inward

Answer

A linear fracture radiating from the impact point across the cranium

Answer

A circumferential fracture encircling the entire base of the skull

Answer

A fracture pattern associated with drowning and water impact

Question 5

In forensic anthropology, 'commingled remains' refers to:

Accepted Answer

Skeletal elements from two or more individuals found mixed together

Answer

Remains that have been burned or charred beyond visual recognition

Answer

Remains that have been intentionally moved from their original deposition site

Answer

Remains showing extensive perimortem blunt force skeletal trauma

Question 6

The Minimum Number of Individuals (MNI) in a commingled assemblage is calculated by:

Accepted Answer

Identifying the most frequently represented skeletal element after accounting for bilateral pairing

Answer

Dividing the total count of all bone fragments by the expected number of bones per skeleton

Answer

DNA profiling of each bone fragment and matching unique profiles

Answer

Calculating average recovered bone mass divided by the mean weight of a complete skeleton

Question 7

Which technique is the standard approach used by forensic anthropologists for facial approximation (reconstruction) from skeletal remains?

Accepted Answer

Tissue depth marker method applying average soft tissue depths at anatomical landmarks

Answer

Neutron activation analysis of trace elements in bone

Answer

Gas chromatography-mass spectrometry of bone lipid profiles

Answer

Scanning electron microscopy of surface bone microstructure
