What three bones make up the os coxa and
fuse together to make a single bone during
development?
The ilium, ischium, and pubis
What type of joint is the femur?
On its proximal end, the femur forms a smooth, spherical process known as the head of the femur. The head of the femur forms the ball-and-socket hip joint with the cup-shaped acetabulum of the coxal (hip) bone.
What is the human dental pattern?
2.1.2.3 for upper teeth: 2 incisors, 1 canine, 2 premolars, and 3 molars
Mesial surface
Surface towards the midline of the mouth
Distal surface
Surface away from the midline of the mouth
Occlusal surface
The biting surface
Lingual surface
Surface facing the inside (tongue / palate) of the mouth
Buccal surface
Surface facing the outside (cheek) of the mouth
What is the difference between trabecular and
cortical bone?
Trabecular bone - cancellous or spongy bone
Cortical - compact bone
What rules can we follow to narrow down whether or not a burial is contemporary vs. non-contemporary?
State of preservation, body modification, personal belongings, conditions of internment

Search & Discovery: What to look for from the surface
Density of vegetation - how heavy, debris, camouflage of burial by perpetrator
Perimeters of a crime scene- what are they?
Inner core value - where evidence is concentrated
Crime scene perimeter - potential area for crime

Rigor mortis
Stiffening of body. Tissue runs out of ATP. Usually starts 2-4 hours after death and peaks about 10-12 hours then subsides
Livor mortis
Settling of blood whitens upper areas of body. Purplish discoloration in dependent portions. Appears a couple of hours after death and reaches max in 8-12 hours
Autolysis
The destruction of cells or tissues by their own enzymes, especially those released by lysosomes
Postmortem interval
The time that has elapsed since a person has died. If the time in question is not known, a number of medical/scientific techniques are used to determine it.
Fresh
Livor mortis, rigor mortis, body cooling
Early decomposition - stage 1
Bloating - production of methane, and body acquires a greenish tint.
Early decomposition - stage 2
Bloating released, sagging of flesh, autolysis, skin slippage, greenish discoloration, hair slippage
Advanced decomposition
Beginning skeletal exposure, runoff of body fluids. Buried bodies decay slower.
Adipocere - greyish white "cheesy" substance
