Firming of tissues
Loss of elasticity (begin firming)
Drying of tissues
Tissues Distension - rounding of fingertips, lips, and toes
Mottling of tissues (bleaching)

pH stands for
Potential of Hydrogen
An acidic pH is
1-6.9
As the pH number increases, the level of acidity _______
Decreases
A neutral pH is
7.0
A basic pH is
7.1-14
As the pH number increases, the level of alkalinity
Increases
In life, the pH varies between
7.35 - 7.45
Upon death, the pH starts to _______
Decrease
As the pH of a dead person goes from 7.35 down to 7.0, this is known as
Primary Stage Flaccidity
During the primary stage flaccidity, the body is
Very limber
Once at 7.0, the pH continues to move toward acidity, stopping at around 5.5-6.5. It will then start to rise returning to 7.0. This stage is known as
Rigor
Once at 7.0, the pH will continue to rise into the Alkalinity range, increasing as time goes on. This stage is known as
Secondary Flaccidity
Upon the pH raising to ___, the bacteria begins to thrive
8.0
When the bacteria thrives at pH of 8.0, the stage of ______ begins to hasten
Decomposition
If the stage of primary flaccidity is only a few seconds long, this is known as
Instantaneous Rigor Mortis
Instantaneous rigor mortis occurs when death occurs how?
Suddenly and in situation as stress
Relieving rigor mortis must be done when?
Prior to Embalming
What are the four ways to relieve rigor mortis?
Rotate
Flex
Extend
Massage
What law states that rigor will first appear in the face, neck, thoracic and abdominal cavities and dissipate in the same order?
Nysten’s Law
People with less muscle will go into rigor ____
Faster
People with less muscle will stay in the stage of rigor _____
Shorter
