4 Means of Natural Preservation
Dry heat - egypt, dry cold - peru, freezing - alps, peat bogs soil preservation - ireland/scotland
Purpose of embalming report?
Keep records of everything body has gone through, keep a paper trail in case something goes wrong.
2 Significant blood discolourations that occur after death and what differentiates them
Livor Mortis and Postmortem Stain. LM is intravascular and not permanent, PS is extravascular and permanent.
What condition causes body temperature to continue rising after death and why does it happen?
Postmortem Caloricity. Occurs when tissues break down & bacteria is still metabolised without the heat created (when that occurs) being able to escape.
What force causes livor mortis to occur in the dependent areas of the body? (This part doesn’t make sense but the prof put it so…) What are the physical changes that account for this?
Gravity causes blood to settle - which is hypostasis. The settled blood (hypostasis) causes livor mortis.
What is autolysis?
When enzymes in cells degrade/break down and cause the cells to digest/cannibalise themselves.
What are the two sources of enzymatic decomposition?
Autolysis is the result of Lysosomes and is known as a cellular self decomposition/digestion. Two sources are lysosomes and bacterial digestive enzymes.
How does water/other moisture in our body accelerate decomposition?
Water is a part of a chemical reaction called Hydrolysis, which is the splitting of chemical bonds (protein structures specifically) by the addition of water.
Identify one method of mouth closure and explain how it is done. What tools are needed?
Tools: needle injector, wired barbs. Use needle injector to inject the wired barbs into the upper/lower jaw on the NON-VIEWING side of jaw. Twist wires together to secure jaw. Trim wires and tuck behind the teeth towards back of throat.
Why is it important to have a photo of the deceased before shaving them?
So we can determine how to shave/not shave them based on how they presented themselves while living.
Why is it important to apply massage cream (emollient cream) to razor abrasions during arterial injection?
It protects the skin from damage if fluids leak out during the injection.
Why is it important to remove Endotracheal Tubes, Nasopharyngeal tubes, and Tracheostomy tubes ASAP?
They interfere with the setting of features and mark the tissue of the face.
Explain 8 changes that may occur to a body during the agonal period?
- Agonal Algor: body cools
- Agonal Fever: body heats up before death
- Agonal Hypostasis: blood slows in body
- Agonal Capiliary Growth: capilaries dilate when trying to keep body alive/oxygenated
- Agonal Coagulation: blood clots/stops
- Agonal Dehydration: moisture levels decrease
- Agonal Edema: increase in moisture of body
- Translocation: microorganisms move from one part of body to other, where they wouldn’t usually be
CETHFACD
C (coagulation) E (edema) T (translocation) H (hypostatis) F (Fever) A (algor) C (capilary growth) D (dehydration)
Relationship between upper muscous membrane and lower mucous membrane?
Upper mucous membrane is longer and thinner, which makes it so your lower jaw doesn’t protrude when you close your mouth.
What area of the eye is subject to shrinking/darkening if not closed properly?
Inner Canthus.
