041 Chapter 4 Zoological Anatomical Experiments

The basketball court brawl incident has passed, but the follow-up impact of this incident has continued, and finally both sides shook hands and said goodbye, many people were punished with demerits, although the number of people playing on the basketball court did not decrease, but it was much quieter, no one was so loud anymore, or scolded people in a hurry, and became a lot more civilized, which can be regarded as a gain and loss.

The academy issued a notice to us, the basketball team of the academy, the football team is not allowed to happen, especially the conflict with other college classmates, let us restrain and organize the players, and the next "camel cup" should also be very careful, if there is an abuse of the referee, or the player's situation, the situation is serious, the ban is one year or even permanent.

We didn't think it had a big impact, we still had to do something, it was just another topic of conversation and laughter when we were drinking and eating.

After four weeks of theoretical class, the zoology experiment finally opened, the task of the first class is to observe and dissect roundworms, a little heavy, I don't have anything, the other students in the class have been discussing, many people are also planning to change majors this semester, after all, people are a gentle and lovely girl, how can you do these disgusting experiments, the future experiments may be more disgusting, how can you persevere, in the end those who stay should be women.

In the end, the experimental class will still be held, no one can escape, and our zoology teacher is notoriously strict, and the students will not be so indulgent, everyone must do experiments, and in the end he has to check them one by one and ask questions.

The teacher explained and said the precautions on the PPT and let us do the experiment, and there was no demonstration, because the steps and precautions he said, how to dissect the PPT also has a picture explanation, there is no need to demonstrate, after all, this is the simplest experiment, as long as we overcome the mental obstacles, there is not much problem, but this overcoming psychological obstacles is a big problem for many people.

It's a pity that roundworms are not alive, but impregnated specimens that have been soaked in formalin for an unknown amount of time, and although they are not as vivid as living animals, they look okay and a little disgusting, so I don't care.

I took the specimen out of the water tank with tweezers, washed it with tap water, put it on the wax tray, and touched it with my hand, it felt good, very lubricated, very soft, and elastic. There are no gloves, because the specimens have been sterilized and sterilized, and they are cleaner than me, as long as they are not disgusted, they can be used as they please.

Gently put it under the stereoscope to zoom in and observe, distinguish the head and tail, male and female, it is not that I have not seen roundworms before, but I have never seen such a close and serious observation, and I have seen the obvious features of the head and tail, as well as the body line, the female genitals and so on. The more I looked at it, the more I felt that it was similar to the noodles I usually eat, which reminded me of the ramen in the morning, and I thought it was interesting to compare the difference between the two.

After looking around the laboratory, I found that there were only a few "warriors" like me who started directly, and most of them were still grinding and chirping, carefully holding tweezers to play, and some girls were even far away and unwilling to do it.

"Mr. Tao (Guo Juntao), do you think this is particularly elastic, it is definitely stronger than the ramen in the canteen, and there should be no difference between splashing oil and pouring oil on spicy noodles. ”

"Let's eat noodles at noon, do you dare!"

Our deliberate ridicule caused a burst of abuse from other people, many of whom were even a little sick to their stomachs, and some girls who had barely mustered up the courage made us sick and unwilling to do it again.

After the observation, pick up the surgical scissors and tweezers and start to dissect carefully, you must carefully and gently cut the epidermis of the roundworm, can not destroy the organs in the knife, intestines or something, the incision should also be beautiful, straight can not be too ugly, this is a technical job, not only to be bold, but also to be careful, fortunately I have both. After being dissected, it was placed under the stereoscope for observation, and the internal structure was not damaged and perfect. I'm also one of the quickest people to get it done, and the others, especially some of the girls, haven't even started yet.

"Brother Gao Fei, help me, people won't get it, I'm a kind and lovely girl, this is too cruel, people can't do it!"

Xin Yu deliberately sold cuteness like me, a fellow countryman, to ask for help, and had to help.

"OK! Just watch from the sidelines, I'll do it!"

"I know you're finally ready, I'll invite you to eat ramen later!"

didn't say anything, just started dissecting, this time more proficient and more serious, after all, it was done for others, and it would be embarrassing if it wasn't done well.

"Is this just a male or a female? I don't dare look closely. ”

"Guess what? Take a magnifying glass and look at its genitals! Don't tell me you're shy. ”

"Hehe, you're so dirty!"

"The experiment report is still made up randomly, anyway, the teacher doesn't know its gender and specific situation. Isn't that right?"

It's been done in a few minutes, it's not difficult, it just depends on whether you can use it or not, and whether you can do it. It's okay to go around in a circle, see what everyone does, Guo Juntao, the school committee, is already teaching female classmates by hand, and he makes jokes from time to time, hey! I don't know how many girls will be harmed.

With the help of another female classmate, Luo Yixuan has been dissected for a while, but it is a bit miserable, the incision is crooked, and the internal organs are also destroyed, and he is preparing to dissect the next one.

They have done a good job, the first dissection is a disgusting animal like roundworms, and they can still do it, which is already a big breakthrough, maybe they haven't even seen a chicken kill at home before, unlike me, who have dealt with countless large and small fish, killed and fed dogs for two years with their own hands, and will help kill New Year's pigs every New Year, classmates who died in car accidents, etc., I haven't seen any scenes.

Looking at Chengfeng, who was still a little hesitant, and her teammate Li Jie, who had already run to the side, I walked over,

"Do you need help? Why don't I demonstrate it first, you watch from the sidelines, and if you think it's acceptable, you try again, and I'll watch it for you." ”

"Okay! Thank you. This one is a problem for you. ”

"Don't be so angry, you can still play happily in the future, I didn't say before that if there is any problem, you will find me, I am always available. Otherwise, I'm sorry for your 'chivalrous brother'! ”

Seeing her smile, I began to explain as I did:

"This is the head, look carefully at its mouthparts, in this position (0.7cm from the tail end) start cutting, feel the scissors inserted into the line, not too deep, come, you help me insert a pin to fix the skin, I will continue to cut ......"

Under my guidance, in the end, she also plucked up the courage to cut the final head by herself, this specimen was also very good, not ugly, watching her carefully observe under the stereoscope, I gently returned to my position, with a microscope to observe some roundworms, planarians, etc. Continue my experiment and draw a diagram of the observed structure.

After class, everyone tacitly did not mention the problem of eating at noon, and hurriedly packed up their things and left this terrible laboratory.

Although I breathe through my mouth, the smell of the laboratory can even be smelled in my nose, which has not been sensitive at all for many years of rhinitis, and the pungent chemicals in the laboratory make my throat very uncomfortable. I didn't have an appetite either, and I didn't want to eat yet, so I went straight to Minghu to relax and blow the wind.

The dead grass on the meadows by the lake had begun to turn green, and the willows were ready to bud, though still a little cold. The ice on the lake has melted a lot, it's already April, spring here has quietly arrived, the sun is so bright, warm, so it's just right, Lan also likes this kind of weather, we sit on the stools and snuggle up to each other, chat, forget all our worries, even the occasional wind is not so cold.

Lately I've seen Lan less and less often, and we seem to be getting farther and farther away, even though the distance between us is palpable.
