I make a popular science video and all the emperors learn from it!

【Start the second short video of popular science】

【2: Forensic Anatomy】

【Forensic medicine is a medical discipline that studies and solves legal-related problems such as personal injury, death, and identification, provides clues for criminal investigations, and provides evidence for trials.】

【The main work is:】

【Contact broken corpses, rotting corpses, floating corpses, analyze knife wounds, gunshot wounds, blow injuries, etc., so as to peel off the cocoons and find the truth....】

【One of the research objects of forensic medicine: corpses】

【Corpses are a classic subject of forensic science】

【Forensic pathology is a discipline that studies human injury, death and their development. The main research content includes the mechanisms, processes and phenomena of injury and death, mainly various deaths that did not occur in the hospital or occurred in the hospital, but there are disputes of deaths】

【Such as rigor mortis, cold corpse, giant view, postmortem childbirth, mismatched characters, drowning gloves, ~ abnormal undressing phenomenon】

【The second research object of forensic medicine: living body-】

【The research objects of forensic medicine include not only living bodies, but also living people.】

【Forensic clinical medicine focuses on legal-related human injuries, disabilities and other pathologies...】

【The third research object of forensic medicine:】

【body or part of a living body】

【Bodies or parts of living bodies are more common at crime scenes】

【Such as fallen hair, blood stains on the wall, saliva on cigarette butts, cut nails, marks on clothes...】

【These biological evidences from corpses or living bodies often play a key role in the detection of cases.】

【......】

【How powerful are forensic doctors?】

【Watch a video first】

【Just because a bored netizen posted a photo of the floor with some water stains on it, and gave it a title: Guess based on intuition and forensic analysis, where did this water mark come from?】

【This attracted a lot of forensic science students to analyze in the comment area.】

【:? How did you know I was a forensic scientist?

To do a rough analysis, first eliminate the condensation water on the bottles and cans, because neither the sputtering shape nor the liquid form matches.

It's more like some kind of fruit falling to the ground.

Among common fruits, considering the water content and shape, the closest ones should be apples or pears.

I prefer pears because the free water of apples is not as high as that of pears.

If the free fall has no initial velocity and the board on the ground is the width of a standard board, the fall height should be 80 to 90 centimeters.

It would be nice if I had a ruler to measure the marks.

Or go to the bureau tomorrow and use your colleague’s software to simulate it.】

【...】

【And that bored netizen came out and replied: It’s a pear!】

【From small to large, you can see how terrifying the forensic doctor's control over details is!】

【In addition, forensic doctors have accumulated a lot of experience in handling cases.】

【They can often quickly identify a case, whether it is suicide or homicide.】

【Example: Hanged corpse】

【If you point your toes at someone, it's likely they were murdered.】

【If someone hangs himself, the deceased will stand on tiptoes as hard as he can before death. After death, the toes will inevitably droop due to the influence of gravity.】

【And if it is within 48 hours, after being strangled by the murderer, he pretends to hang himself, and the body with rigor mortis will point its toes towards the person.】

【At this time, once the forensic doctor unties the rope around the corpse's neck, he may hear the corpse's code words.】

【"sand...sand...sand"】

【No matter what the corpse wants to say, the medical examiner must pretend not to hear it.】

【This sound is actually not a secret message left by the deceased before his death, but the whimpering sound made by the putrid gases inside the corpse, which are discharged along the airway at the moment when the corpse's neck is released.】

【In addition, there were bodies at the fire scene】

【If the eyelashes of the deceased disappear, it is initially determined to be homicide.】

【Because when a living person is burned to death, the high temperature of the flame will cause him to close his eyes tightly. 】(To read exciting novels, go to Feilu Novel Network!)

【At this time, the lower eyelashes close to the eyelids are hidden in the eyes and will not be burned. At the same time, the crow's feet are closed, forming goose claw-shaped marks on the face.】

【When burned after death, the eyes will not be closed tightly, the eyelashes will be burned off, and the crow's feet will not have goose claw marks.】

【...】

【And these are just the tip of the iceberg of the experience that forensic doctors have summarized.】

【In addition to meticulous observation and rich experience, forensic scientists also need to use all kinds of knowledge they have learned】

【For example, forensic theory, human anatomy, pathology, internal medicine, surgery, pediatrics, obstetrics and gynecology, criminal investigation technology, forensic pathology, forensic toxicology, forensic clinical science, forensic evidence, forensic anthropology, etc.】

【In addition to not having a medical qualification certificate】

【A forensic doctor can be said to be an all-round doctor】

【And when forensic doctors find something suspicious at a crime scene, they begin to use the knowledge they have learned and modern equipment to identify what the suspicious part is?】

【The way to confirm is to test its ingredients and in turn confirm the suspicious substance】

【After that, they started thinking about another question】

【How on earth were the suspicious parts brought to the scene?】

【This requires their meticulous observation and investigation and reasoning abilities....】

【Finally, they have to think about the most important question】[]

【Whose is the suspicious object?】

【There are no identical leaves in the world, nor are there exactly the same people.】

【The most accurate way to distinguish human beings, apart from appearance characteristics, is to detect DNA】

【Since everyone's DNA cannot be exactly the same, after the test results come out, the DNA can be compared or evidence can be collected from the suspect to identify the criminal suspect.】

【At the same time, the test results are also part of the criminal evidence.】

【......】

At first, ancient people from all dynasties frowned.

Many people complained:"Studying corpses is so unlucky!"

After seeing the capabilities of forensic doctors.

Everyone was dumbfounded.

The common people discovered novel things and found topics to chat about.

"Forensic doctor? This seems to be a work from later generations."

"Yes, it sounds like it to me. It’s similar to the yamen’s job. You deal with corpses every day."

"Harmful! They are much more powerful than Wu Zuo. Look, they can learn everything. They know more than the officials today. They are doctors and can also treat diseases."

"Do you have so much knowledge about killing people?"

"I learned it, I have to be more careful when killing people in the future."

"I go! Brothers, hurry up and report to the official."
