Medical law is a legal course related to medicine and a new branch of law to solve more and more medical disputes. Forensic medicine sprouted as early as the ancient Song Dynasty, represented by Song Ci. Forensic medicine is the application of natural science knowledge such as medicine and biochemistry to solve legal problems related to medicine and provide evidence for investigation and trial. The earliest forensic medicine is actually forensic pathology. The main work is to get the cause of death, the nature of death, the time of death and so on through the examination of corpses. With the development of law and medicine, forensic evidence science has emerged, which mainly tests some biological samples, such as DNA testing and paternity testing, and belongs to the category of forensic evidence science. Forensic clinical medicine also came into being, mainly to examine some people injured in traffic accidents or fights, so as to judge whether they are seriously injured, slightly injured or disabled at several levels. In addition, there are sub-disciplines such as forensic anthropology, forensic psychiatry, forensic toxicology analysis and forensic entomology. Undergraduate students majoring in forensic medicine in medical colleges should learn all the subjects I mentioned above except the courses that ordinary medical students should learn. If you are a graduate student majoring in forensic medicine, you only need to choose one of the above branches for special research.
