Forensic Week

Skeletons are good age markers because teeth and bones mature at fairly predictable rates. For toddlers to teenagers up to age 21, teeth are the most accurate age indicators. Some of the best indicators of adult age are in the pelvis.

A baby's bones begin to grow in the womb. At birth, the skeleton is partially formed

At birth, the ends of the long bones are mainly cartilage, with centers of bone beginning to form inside

Some (almost the whole skeleton) the bones are not fused together.

The wear and tear of the bones and the back of the skull can also tell, the more wear and tear there is, the older the person is and the skull, if the skull is not completely fused, then they are younger then 21, if it is fused, they are 21 or older.

Which X-Ray is an older person?

-how to find the gender of a skeleton is simple, there are many ways, but the two major easy ways are the pelvis ad the skull.

-the pelvis is the easiest because if the pelvis is wider and easier to move your thumb around in, then it is a female because a female needs a wide pelvis to carry child birth.

-a males pelvis is small and hard to move your thumb because a pelvis is made for locomotion.

-A skull is hard, but yet easy to find gender. If the skull had a broad brow ridge and a square chin, it’s a male, if its more petite, then it is a female.

Determining the height of a skeleton involves reassembling the skeleton and measuring the length of significant bones

By adding 10-11cm or four inches onto the bone length, it accounts for the missing tissue and muscle.

The longer the bone is, the better and more accurate the estimate will be, so the femur is measured first

The human height measures roughly two and two thirds the length of the femur, though it also depends on the race and sex of the skeleton.

Longer the femur, the taller the person.

Ante mortem is before death, like a broken bone or a bullet trapped around the bone because the bone grew around it.

Per mortem is at the time of death, like what killed them

Post mortem is after time of death, an injury that occurs after the death

Mortems

Which is ante post or peri mortem?
