-This is a condition wherein the fatty tissues of the body are transformed to soft brownish-white substance
SAPONIFICATION OR ADIPOCERE FORMATION
soft brownish-white substance known as
adipocere
The layer of subcutaneous tissue is the frequent site of its formation.
SAPONIFICATION OR ADIPOCERE FORMATION
is a soapy or waxy material, rancid in smell, dissolves in alcohol and ether when burned produces yellow flame.
ADIPOCERE
known as corpse wax or grave wax or mortuary wax
ADIPOCERE
-The principles involved in artificial mummification are:
(a) Acceleration of the evaporation of the tissue fluid of the body before the actual onset of decomposition.
(b) Addition of some body preservatives to inhibit decomposition and to allow evaporation of fluid. This is made by treatment of the body with arsenic, formalin, resinous or tarry materials.
ARTIFICIAL MUMMIFICATION
When a person is buried in hot, arid, sandy soil, there will be insufficient moisture for the growth and multiplication of putrefactive bacteria. The body will become dehydrated and mummified which is caused by the forces of nature.
NATURAL MUMMIFICATION
KINDS OF MUMMIFICATION
(1) NATURAL MUMMIFICATION
(2) ARTIFICIAL MUMMIFICATION
-is the complete dehydration of all body tissue which results in the shivering and preservation of the body. A cadaver left in an extremely dry, hot area will mummify in about a year and will remain in this condition for several years if undisturbed by animal or insect
-is observed in warm countries where evaporation of body fluid takes place earlier and faster than decomposition. Death in deserts, like in Egypt, the body has more tendency to mummify.
MUMMIFICATION
-is the breaking down of the complex proteins into simpler components associated with the evolution of foul smelling gasses and accompanied by the change of color of the body.
PUTREFACTION
SPECIAL MODIFICATION OF PUTREFACTION
A. MUMMIFICATION
B. SAPONIFICATION OR ADIPOCERE FORMATION
-This appears during the later stage of its formation when the blood has coagulated inside the blood vessels or has diffused into the tissues of the body
DIFFUSION LIVIDITY
-Any change of position will not change the location of the lividity.
DIFFUSION LIVIDITY
-The blood merely gravitates into the most dependent portions of the body but still inside the blood vessels and still fluid in form.
HYPOSTATIC LIVIDITY
-Any change of position of the body leads to the formation of the lividity in another place.
-This occurs during the early stage of its formation.
HYPOSTATIC LIVIDITY
TYPES OF POST MORTEM LIVIDITY
- HYPOSTATIC LIVIDITY
- DIFFUSION LIVIDITY
The investigator can press on the skin in the dependent regions and if the skin blanches, death has probably occurred less than
12 HOURS
Post Mortem Lividity is also known as
CADAVERIC LIVIDITY
POST-MORTEM SUGGILLATION
POST-MORTEM HYPOSTASIS OR
LIVOR MORTIS
It is a purplish discoloration of the body that occurs on those parts of the body which are nearest the floor.
POST-MORTEM LIVIDITY
This discoloration is caused by the settling of the blood by gravity into those areas. During life the blood is under pressure and circulating. After death, the pressure falls to zero and the blood begins to settle by gravity so that no matter what the position the body may be in those positions of the body which are lowest will be the areas the blood will settle. Under most conditions this discoloration will begin to be apparent from one to two hours after death.(Montojo,n.d.)
POST-MORTEM LIVIDITY
-A muscular change characterized by the softness and flaccidity of the muscles in which no longer responses to electrical or mechanical stimuli due to dissolution of the muscle protein that have been previously coagulated during the stage of rigor mortis.
STAGE OF SECONDARY FLACCIDITY OR SECONDARY RELAXATION
-This stage is onset of putrefaction
STAGE OF SECONDARY FLACCIDITY OR SECONDARY RELAXATION
THE ENTIRE MUSCULAR TISSUE PASSES THREE STAGES AFTER DEATH
A. STAGE OF PRIMARY FLACCIDITY
B. STAGE OF POST-MORTEM RIGIDITY
C. STAGE OF SECONDARY FLACCIDITY OR SECONDARY RELAXATION
-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
