ALGOR MORTIS - SAPONIFICATION Flashcards
(40 cards)
The progressive FALL OF THE BODY TEMPERATURE is one of the most prominent signs of death.
Algor Mortis or Cooling of the Body
The NORMAL body temperature in a living person is?
37°C or 98.3°F
The DEAD body temperature in a living person is?
15 to 20°F
After death, there is complete RELAXATION OF THE WHOLE MUSCULAR system.
Changes in the Muscle
After death, The entire muscular system
is CONTRACTILE for HOW LONG?
three to six hours
The Entire Muscular Tissue Passes Three Stages After Death, namely;
a. Stage of Primary Flaccidity ((post-mortem muscular irritability)
b. Stage of post-mortem rigidity
c. Stage of Secondary Flaccidity or Secondary Relaxation
It is the stage of muscular change upon death characterized the relaxation of muscles and LOSS OF THEIR NATURAL TONE, so the jaw or head drops down, the thorax collapses and the limbs becomes flaccid and the splinters relax
Stage of Primary Flaccidity ((post-mortem muscular irritability)
It is the STIFFENING OF THE MUSCLE of the body after death due to chemical changes within the muscle tissue itself
Stage of post-mortem rigidity
In warm countries, this stage sets in from 2-3 HOURS after death
Stage of post-mortem rigidity
It may last from 18 – 36 HOURS and its disappearance is concomitant with the onset of Stage of post-mortem rigidityputrefaction.
Stage of post-mortem rigidity
This stage lasts for 3-4 HOURS after
death.
Stage of Primary Flaccidity ((post-mortem muscular irritability)
Post-mortem rigidity is also known as
Rigor Mortis
Conditions Simulating Rigor Mortis:
- Heat Stiffening
- Cold Stiffening
- Cadaveric Spasm or Instantaneous Rigor
is commonly observed when the body of a person is PLACED IN BOILING FLUID or when the body is burned to death
Heat Stiffening
A condition characterized by hardening of the muscles due to coagulation of muscle proteins when
the dead body is exposed to INTENSE HEAT AS BY BURNING or immersion in a hot liquid.
Heat Stiffening
It is due to the solidification of fat when
the body is exposed to FREEZING TEMPERATURE
Cold Stiffening
The stiffening of the body may be manifested when the BODY IS FROZEN, but exposure to warm
condition will make such stiffening disappear
Cold Stiffening
It involves ALL THE MUSCLES OF THE BODY whether
voluntary or involuntary.
RIGOR MORTIS
It is the INSTANT STIFFENING of a certain group of muscles which occurs immediately at the moment
of death, although its cause is unknown, it is associated with violent death due to extreme nervous tension
and injury to the central nervous system
Cadaveric Spasm or Instantaneous Rigor
It appears THREE TO SIX HOURS after death.
RIGOR MORTIS
It may be utilized by a medical jurist to APPROXIMATE THE TIME OF DEATH
RIGOR MORTIS
is a NATURAL PHENOMENA which occurs after
death.
RIGOR MORTIS
It APPEARS IMMEDIATELY after death.
CADAVERIC SPASM
It involves ONLY A CERTAIN MUSCLE or
group of muscles and are
asymmetrical
CADAVERIC SPASM
