Rigor mortis

estimate time of death, we can first narrow down the window on the timeline by looking at the stages of rigor mortis and lividity. At the autopsy, it was observed that the victim was in full rigor mortis. The human body is typically in full rigor, or stiffness of the muscles, between 8 to 24 hours after death, during which time the muscles become completely stiff and stay stiff before rigor mortis dissipates (Crowe, n.d.). In this case, it may have been affected in that this process might have…

heart pumping blood, the blood stops flowing thru the body. Blood just stops wherever it is and sits.The skin changes color depending on where the non moving blood is still sitting. Livor mortis start, which is the blood gelling in our blood vessels. Algor mortis is when the body temp starts to cool. Then Rigor mortis is when the body stiffens. As the muscles slowly die some slight twitching can occur. This doesn’t mean the bodies alive, they’re just reflexes. Because the…

Have you ever wondered what happens after death? More specifically what happens to the Human body after death? Death is defined as an “irreversible cessation of circulatory and respiratory functions, or irreversible cessation of all functions of the entire brain, including the brain stem. Is dead.” I will be talking about the irreversible cessation of circulatory and respiratory functions. This because if one loses functions of the entire brain their body can still live due to today’s technology…

There are so many misconceptions arise when you talk about a person having an autopsy. First of all people think that everyone has an autopsy upon the calling of death. Second people think that person is automatic identified and what happens to their personal effects care for? Next, people think that the organs are kept and donated to other individuals. Another question I get all the time is that is there time where the body will sit up on its own after death. Finally is that what happens to…

someone died such are rigor mortis, this happens within 24 hours after a death, this is when the body's muscles relax then become more rigid. Algor mortis is another way they use to determine when the death occurred, it is the gradually cooling of the body after death,pathologists have to consider factors such as where that body is, the temperature in the air, and the size of the body to determine the time in death from the temperature. Another method they use is livor mortis, within 12 hours…

5. Normal muscle contraction occurs in a series of steps, and they are as follows: First, a motor neuron must have acetylcholine released in the synaptic cleft. The acetylcholine is then able to bind with receptors found in the cell membrane. This binding causes the Ca+/Na+ channels to open. The terminal cisternae then releases calcium into the muscle fiber. Calcium will begin to bind to troponin. The troponin moves tropomyosin out of the way since it blocks the actin’s active site. Next, actin…

It was almost as if I had been stricken with rigor mortis as the last of her words evaded into thin air, sliding off of her tongue like venom. I was filled with emotions resembling that of both shell shock and astonishment, as the still nameless, elderly woman continued holding my face by the clutches of her long, gaunt fingers. Only a few seconds had passed while she continued to grasp me, but I began to panic. I wasn’t sure what could follow an event as strange and eerie as that, and I hadn’t…

According to Massimo A. Bonfantini and Giampaolo Proni in their article “To Guess or Not to Guess,” abduction is commonly used in the detection of crime when solving cases and inferring hypothesizes based on evidence and imagination. Abduction is commonly defined as “identify[ing] possible causes of resulting events” through hypothesizing with observed data (Bonfantini and Proni 123). In other words, this definition means that abduction involves observing data and interpreting this data with…

Otzi is the oldest ice mummy: 5,300 years old. The mummified, body of Ötzi was discovered in 1991 by no attention by some two German tourists. The body, stuck in the Schnalstal glacier, offers a glimpse at the European Copper Age. Ever since this mystery has been discoveried, everybody has wanted to know why the mysterious Iceman died. In 2000, the body was temporarily in for investigation. It appeared that his last meal was made of unleavened bread and some greens, but also venison, thus the…
