JURISPRUDENCE Flashcards
Appearence of Maggots
feature of putrefication helps estimate time since death 18-36hrs = eggs layed 24hrs= hatch 3-5days=pupa 4-5days=adult
Forensic ENTOMOLOGY
study of insects that infest a dead body is known as forensic entomology
LATE SIGNS OF MOLECULAR DEATH
PAM
PUTREFICATION
ADIPOCERE FORMATION
MUMMIFICATION
PUTREFICATION
Stiffening due to accumulation of putrefactive gases in the tissue , which causes FALSE RIGIDITY resulting in stiff limbs
factors responsible of putrefication
Autolysis (3-4 hrs death upto 2-3days)
bacterial action
ADIPOCERE FORMATION
synonym saponification
modification of putrefication process
fatty tissues of the body=hydrolysed into fatty acids
ML importance of ADIPOCERE FORMATION
TCIB mnemonic
TCIB mnemonic
T= time since death C= cause of death I = Identity of the person B = burial place
time required for adipocre formation
3-6 weeks
MUMMIFICATION
late sign of molecular death
definition
in which there is dehydration or desiccation of body tissue and viscera after death
mummification vs adipocere
mummification dehydration of body tissue or viscera fter death
adipocere fatty tissues of body hydrolysed into fatty acids
ML IMP OF MUMMIFICATION
Same as adipocere formation
TCIB
EMBALMING
artificial mummified bodies for purpose of preservation
Natural preservatives
Adipocere formation
Mummification
artificial preservation
Embalming
cold storage
TIME SINCE DEATH factors responsible
cooling of the body post mortem lividity Rigor mortis decomposition changes Content of stomach and bowels content of Urinary bladder biochemical changes circumstantial evidence
Post mortem calarocity def
and occurence
phenomenon in which body temperature of corpse rises or remains usually high for upto 2hrs
occurs in bodies who suffered voilent muscle contraction at time of death
asphysxial deaths
tetanus
strychnine poisoning
acute bacterial infections or viral infections
post mortem lividity
PML is the purplish discoloaration the skin of the dependent parts of the body after death
due to accumilation of fluid blood in toneless capillaries and small veins of the skin and organs
mechanism
due to blood gravitating and distending the toneless capillaries and small veins
fixaton of PML is due to stagnation of blood and not due to coagulation
PML ML IMPORTANCE
MNEMONIC STPCM
sign of death time since death position cause of death mode of death
PML relation to tsd
first 1-3hrs= mottled patches
next 3-6hrs= bigger patches
next 6-8hrs=fixed and fully developed patches
martch of RIGOR MORTIS
12hrs= developing phase
12hrs= persist, static phase
12hrs=passing off phase
muscular changes in molecular death(early sign)
primary relaxation
rigor mortis
secondary relaxation
rigor mortis definition
it is a condition characterized by stiffening , shortning and opacity of the muscles which follow the period of primary relaxation after death
conditions stimulating rigor mortis
heat coagulation / heat stiffening
freezing or cold stiffening
putrefication
cadaveric spasm
cadaveric spasm
a condition characterized by stiffening of the mucles immediately after death
WITH OUT THE PRIMARY RELAXATION STAGE unlike rigor mortis
