Knowledge and Practice

After the start of the school year, the courses are full, and the partial dissection experiment class. There are only 2 corpses in the school, one male and one female. The muscles of the old corpses are basically shriveled and shrunk into thin pieces. Even the smell of formalin is diluted a lot. Even so, the status of these two corpses should not be underestimated. As soon as the teacher of the anatomy class entered the classroom, he scolded and stopped the classmates who were holding a few bones and gesturing to their arms around the corpses. After telling the price of the corpse in Bai's way, he frightened away the owed classmates.

In the laboratory, all the students in a class were standing, and had already circled the corpse three times from the inside to the outside. Those who stood in the outermost row brought stools and half-kneeled on the stools to "look out".

There are still fresh corpses in many TV dramas in some academically strong schools. According to the anatomy teacher’s recollection, they even existed when he was studying. Here, the source of corpses is less.Putting it into the society, when it comes to internships, in the current environment, there are fewer opportunities for interns to do it. The stronger the patient's sense of protection and distrust, the teachers who teach are afraid to let the students do it.

The teacher of anatomy class could not help but sighed to the students and said: "At that time, all the lumbar punctures and thoracic punctures were guided by the teacher to let the patients wear them directly until they felt it. Of course, the patients in the past were different from those now. You have to practice, you are familiar with the model, we have limited resources now, the students on the 20th to 40th will follow me first, and the students before the 20th are going to the opposite classroom to watch the video, and I will replace you when it is ready."

Xiao Xingyi and Zhang Chengyu were both in the front row, so they went to the opposite classroom together. The video was played in an ordinary large classroom, and the documentary "Anatomyforbeginners German Introduction to Decryption" was playing on the projector. The teaching video exists as a model of the teaching level. Professor John Lee and Dr. Gunthervon Hagens from the Institute of Anatomy of the University of Heidelberg in Germany explain the entire anatomical process of the whole human body. ask questions.

The on-site dissection in the video uses unprocessed corpses, which have a high degree of freshness, little adhesion between tissues, and relatively good softness and flexibility of organs. Due to the short video time and fast dissection speed, the use of corpses The rate is very low, and the dissection process is extremely simple and crude.

The professor in the video started to hit one side of the skull with a hammer, and explained what he was doing, "right, it looks like alittle bitgrace, but whole word led do it every day, allanatomies so" (this seems a little violent, but people all over the world do it every day, all anatomist...)

In order to ensure the integrity of the brain tissue, after the percussion force of the surgical scissors on one side was finished, the professor changed the force evenly on the other side. Excavator

"brianisdfficultograntoexpose, becauseitshideaawayinsidethebonescavity"

"nowineedachainsaw, wedonthaveenoughinfront" (now I need to use a chainsaw, we don't have enough in front)

No longer satisfied with the gentle surgical scissors, the professor asked his assistant to bring a chainsaw, "Zizizizi... Weng Weng..."

"..."

Zhang Chengyu's scalp felt numb when he saw it, and he felt that what the saw saw was not the skull of a corpse, but his own skull. He was not the only one who felt the same way as he watched the class. Xiao Xingyi also seemed to frown slightly, and a trace of pain flashed across his calm face. Uncomfortable expression, maybe the chainsaw scene was too refreshing.

However, these discomforts soon became numb after the professor took out the brain tissue and the spinal cord completely. The sound of the chainsaw was intermittent in the video. Xiao Xingyi quickly regained his senses and concentrated on identifying the dissected tissues and organs.

The video of this lesson mainly talks about the motor system, but it covers a wide range of areas, including the nervous system that is closely related to the motor system. The central nervous system corresponding to the sliced ​​​​brain, the range of muscles controlled by neurons, and the movement Reflexive arcs of nerves, these complex names were vividly distorted by Xiao Xing into a group of words that only he could see and understand.

In fact, after the video was completely played, Xiao Xingyi was a little hesitant looking at some pictures and notes he had made. Although in order to speed up the shorthand notes, Xiao Xingyi would occasionally try to use some English abbreviations to replace the words he heard. , but looking back, it was still a part of what he wrote, but he couldn't recall the meaning he wanted to express, which made him a little frustrated.

Zhang Chengyu next to him is not much better. The pages of the books in the first half of the class are well-written, both in Chinese and English. In the books of the second half of the class, there are only a few dashed lines, indicating that the content of this class is over. This visit.

The screening ended, and the teacher appeared outside the classroom on time, "Okay, the top 20 students here come with me, and the students who have been to the laboratory just now come here to watch the video." At this time, the students who watched the anatomy video finally Excited, they swarmed out the door and ran to the laboratory.

The moment Xiao Xing stepped out of the classroom, he remembered that his mobile phone was still in the desk drawer, so he turned back helplessly, and shouted at Zhang Chengyu, "Brother Yu, help me to reserve a seat in front."

"Understood, there is no place, aren't they all standing?" Zhang Chengyu squeezed in front of the crowd without looking back.

Xiao Xingyi took out the mobile phone in the desk, and because of the class, he turned it on mute. The moment he turned on the screen, the chaos and wandering after one class were swept away, and even the autopsy that followed became uncomfortable. So annoying.

The text of WeChat on the screen displayed his most familiar name

Xie An: Are you in class? 10.1 Are you back from vacation?

Without a moment's hesitation, Xiao Xing pressed a few characters, put away his phone, and followed the team of classmates going to the laboratory.

Xiao Xingyi: Come back~ come to pick me up?
