MORS 11 Lecture- vocab and additional notes Flashcards
A non-toxic disinfectant suitable for use on animal tissue.
Antiseptic
Freedom from infection and from any form of life- sterility
Asepsis
An agonal bacterial invasion of the body, usually by the putrefactive bacterial, usually confined to the colon, migrating into the blood vascular and skeleton system.
- presence of bacteria in the blood
Bacteremia
Destructive to bacteria.
Bactericidal
Destruction of bacteria by action of certain chemical substances.
Bacteriolysis
Agent that has the ability to inhibit or retard bacterial growth; no destruction of viability of the microorganism is implied.
Bacteriostatic Agent
Removal of infectious agents by scrubbing and washing, as with hot water, soap, or suitable detergent.
Cleaning
An agent, usually chemical, applied to inanimate objects or surfaces for the purpose of destroying disease-causing microbial agents, but usually not bacterial spores.
Disinfectant
The destruction and or inhibition of most pathogenic organisms and their products in or on the body.
Disinfection
An agent, usually chemical, applied either to inanimate objects or surfaces or living tissues for the purpose of destroying disease-causing microbial agents, but usually not bacterial spores.
Germicide
An agent, usually chemical, that possesses disinfecting properties when applied to a pre-cleaned object or surface.
Sanitizer
A process that renders a substance free of all microorganisms.
Sterilization
Formulated by the action of pure phenol on pure cultures of Bacillus typhosus or other similar bacteria. The relative germicidal value of other disinfectants is determined by comparing their germ killing power with that of phenol under identical conditions.
- Less killing power is less than 1.0
- More killing power is greater than 1.0
Phenol- Coefficient
The process in which a gaseous agent is used to destroy rodents and insects. Some are:
- Hydrogen cyanide
- Sulfur dioxide
- HCHO gas (formaldehyde gas)
Fumigation
An agent which is destructive to insect larvae (maggots are primary larvae), such as:
- Malathion
- Diazinon
- Chlordane
Larvacide
A chemical agent capable of destroying saprophytic or pathogenic fungi such as mold. (Fungi are more resistant than bacteria to chemical agents and can easily survive on an embalmed body.)
Fungicide
Is a poor, almost useless fungicidal agent.
Formaldehyde
Has fungicides built into them.
Preservative jelly, such as Postene (phenol)
- Mucor
- Aspergillis
- Penicillium
Common, most troublesome molds that the embalmer must face
- Carbolated Vaseline
2. Paradichlorobenzene
The fungicides most commonly used by embalmers
A substance able to destroy lice. Example: Rid
Pediculicide
An agent destructive to adult forms of insect life; same chemicals as larvicide.
Pesticide (Insecticide)
The metabolic entity of growth, reproduction and locomotion.
Life
A group of cells will form a tissue, groups of tissue will form organs, groups of organs will form systems, and groups of systems will form an:
- Heart
- Lungs
- Brain
Individual Organism
- Heart
- Lungs
- Brain
Tripod of Life
The irreversible, total cessation of metabolic activity.
- Necrobiosis
- Necrosis
Death
The death of certain groups of cells and their subsequent replacement by new cells in the normal course of bodily activities.
Necrobiosis
The pathological death of certain cells or tissues of a still living body.
- Gangrene
- Dry gangrene
- Wet Gangrene
- Gas Gangrene
Necrosis
Antemortem cellular death.
Gangrene
The result of a blockage or degenerative condition of the arteries (arterial obstruction).
Dry Gangrene
The result of a blockage or a degenerative condition of the veins ( venous obstruction).
Wet Gangrene
Caused by an organism called clostridium perfringen (bacillus welshii).
Gas Gangrene
Life = Gas gangrene
Death =
Tissue Gas
The antemortem development of a bed sore into necrotic tissue which may become fatal.
Decubitus Ulcers
The period just prior to death.
- Death rattle
- Death struggle
- Instantaneous rigor mortis (cadaveric spasm)
Moribund (dying period, agonal period)
A noise made by a moribund person which is caused by air passing through a residue of mucus in the trachea and the posterior oral cavity.
Death Rattle
The semi-convulsive twitches which often occur before death; It is caused by death of the nervous system.
Death Struggle
The last act in life is preserved in death (anything involving sudden or over production of sarcolactic acid. I.e., combat, sports, automobile accidents.
Instantaneous Rigor Mortis (Caderveric spasm)
The condition in which the manifestations of life are feebly maintained.
- Suspended animation
- Catalepsy
Apparent Death
A temporary condition of apparent death with cessation of respiration.
Suspended animation
A condition in which there is a waxy rigidity of the body and the vital phenomena of life are feebly maintained; body does not respond to stimuli.
Catalepsy
The body of the deceased human being including the cremated remains of a person.
1- Cadaver
2- Cremains
3- Thanatology
Human Remains
A dead human body preserved and especially used for dissection. (inject onlys here at school)
Cadaver
Cremated remains; those elements remaining following the cremation of a body.
Cremains
The study of death.
Thanatology
The death of the whole organism, specifically the death of the heart, brain and lungs.
Somatic Death
1- Is the qualitative expression of dying marked by the cessation of cardiac and respiratory activity.
- The period is brief, not more than 5-6 minutes
- The highly specialized cells of the nervous system are dying quickly due to the lack of oxygen (anoxia)
- It is possible during this period to mechanically restore some form of existence, not exactly life, but a state between somatic death and complete cellular death.
Clinical Death (Legal Death)
- The tissue and organs have undergone irreversible changes so that restoration of normal life function is impossible.
- Highly specialized cells are already dead and the remaining cells are dying.
- Complete cellular death has not occurred yet, and the muscles still respond to electrical shock.
- The tissue is becoming acid, and rigor mortis is developing in the muscle tissue.
- Autolysis which is the digestion of tissue cells by their own enzymes is beginning (simply, self-digestion)
- Saprophytic organisms are starting to infiltrate into the bloodstream and skeletal tissue (systems that attract e.coli) from the intestinal tract.
Biological Death
- Asphyxia (apnea)
- Coma
- Syncope
- Anemia
- Astenia
Modes of Somatic Death
Death beginning at the lungs.
Asphyxia (apnea)
Death beginning at the brain.
Coma
