Study Notes
Cause vs. Manner of Death
- The cause of death is the reason for death (e.g., gunshot wound).
- The manner of death is how a person dies (e.g., natural, accidental, suicidal, homicidal, or undetermined).
Algor, Rigor, Livor Mortis
- Livor mortis is the discoloration of the body after death.
- Rigor mortis is the stiffening of muscles after death.
- Algor mortis is the decrease in body temperature after death.
Carbon Monoxide Poisoning
- Carbon monoxide binds to hemoglobin in the blood, preventing oxygen transport throughout the body.
Factors Affecting Body Cooling Rates
- Ambient temperature, clothing, body weight, and muscle mass can all impact how quickly a body cools.
Deaths Investigated by Forensic Pathologists
- Forensic pathologists investigate natural deaths, accidents, suicides, homicides, and undetermined deaths.
Blunt Force Trauma
- Blunt force trauma is caused by unsharpened objects such as falls, collisions, and can create abrasions, contusions, and lacerations.
- Contusions are bruises caused by broken blood vessels below the skin.
- Hematoma is a swollen bruise.
- Lacerations are tears in tissue caused by a sliding or crushing force.
- Abrasions occur when the epidermis is removed due to rubbing against a rough surface.
Incised, Chop, & Penetrating/Perforating Wounds
- Incised wounds are longer than they are deep and are caused by sharp-edged objects.
- Chop wounds are caused by axes, meat cleavers, or machetes.
- Penetrating wounds puncture organs.
- Perforating wounds go through organs.
Autopsy Process
- Trace Evidence such as glass, hair, and fibers can be found at the crime scene or on the body.
- Signs of Struggle are defensive wounds and bruises or cuts.
- A body bag is used to store the body and ensure only evidence from that body is contained.
- The autopsy table is a slanted aluminum table with raised edges and drains. The body block is a rubber or plastic brick used to elevate the patient's back.
- A scalpel is a knife with a small blade used to cut open bodies.
- A Y-incision is a cut from shoulder to shoulder meeting at the breastbone and extending to the pubic bone.
- A bone saw is used to cut through bones.
- A chest plate covers the front of the chest during an autopsy.
- Tissue samples are taken to analyze for trauma or disease.
- Organs are weighed, examined, and cross-sectioned for microscopic examination.
- A toxicology screen is used to test for drugs and poisons.
- During brain examination, the skull is cut open to expose the brain and the brain is removed for examination.
- Baseball stitch is a term used to describe the way the skull is cut open during an autopsy.
- The morgue is a place where dead bodies are stored in the autopsy room.
- An autopsy report documents the steps taken, date, time, place, and who is in attendance. It includes photographs of injuries.
