Chapter 119: New Knowledge

Chunxiao said: "The slave guesses that someone may have sent a message to Doctor Li that he would come!" ”

Lu Ning nodded and motioned for Chunxiao to continue.

Chunxiao carefully fed Lu Ning a mouthful of porridge before continuing: "Last night we were waiting for you to come back for dinner, a pigeon flew in, and after reading the letter, Doctor Li told me to take care of the little boy, saying that you will not come back at night." ”

"I felt that something was wrong, so I said that we were going back to Meizi Village tomorrow, and we also had a free clinic, and Doctor Li said that it would be canceled, and then it was the little boy who pestered him and asked a few words, and Doctor Li asked people to send us over today."

"Pigeons?" Lu Ning swallowed the porridge in his mouth and muttered.

"Yes." Chunxiao handed the spoon to Lu Ning's mouth again, and said, "Two carrier pigeons came last night, and then they were only for Li Gongzi and them, and after reading the letter, he quickly asked the two Tu Gongzi to chase after Doctor Li." Childe, I always felt that something was wrong. ”

Lu Ning also felt that something was wrong.

Two carrier pigeons.

Doctor Lee.

Li Tingxuan.

Does it matter?

And Divine Doctor Li is here, this, Lu Ning can't help but think about it, who notified Divine Doctor Li to come over to see her? Isn't it possible that he has clairvoyance and ears to know that something happened to her here?

Was it notified by the Prince?

Is it necessary to put two carrier pigeons?

And according to her, His Royal Highness the Crown Prince, no, is the relationship between Doctor Li and the entire royal family is not very good?

The possibility that His Royal Highness the Crown Prince will directly send a message to Divine Doctor Li is almost zero, she has nothing to do with His Royal Highness the Prince, it is absolutely impossible for His Royal Highness the Crown Prince to do this kind of thing for her, and it is already the limit to send a letter to Li Tingxuan and ask Li Tingxuan to ask Divine Doctor Li to go over, so the question is, who is the person who directly sent the message to Divine Doctor Li?

Lu Ning couldn't figure it out.

Forget it, if you can't think of it, you don't want to think about it, she is a patient, and thinking too much about the patient will affect the recovery.

Just when she wanted to lie down and sleep for a while, she heard Grandma Liu's voice in a trance: "Where is it?" Where is Ah Ning? ”

She looked at Chunxiao, who also looked at her, and asked uncertainly, "Grandma Liu?" ”

As soon as the words fell, I heard Xibao's crisp voice: "Grandma, why are you here?" Are you here to see Daddy? ”

"yes!" Qin hugged Xibao: "Where's Daddy?" ”

Xibao pointed: "What about inside?" I can just move, and I'm drinking porridge! I'll take you in. ”

Children have no twists and turns, they can say whatever they know, although Xibao is smart, but in the face of relatives, he still has something to say.

Qin's nose is sour, just able to move? What a wound it must be!

But when she saw Lu Ning, she walked over quickly, her hands and feet trembled, how could she be injured like this!

Old Liu Tou and Liu Dazhu's throats were tight, and they couldn't speak, and they suddenly felt that their eyes were dark, look at Lu Ning's injury, and then look at Liu Xubin's, at a glance, they knew that Liu Xubin was the one who was being protected!

You said that you are a young man, how can you let the girl's family stand in front of you in trouble!

A Ning is a girl's family! How can you!

Old Liu Tou was so angry that he kicked Liu Xubin on his back-

"Eh-" Lu Ning sat up straight and hurriedly shouted: "Don't fight, don't fight, he still has injuries on his body!" ”

Concussions are no joke, hey!

But with this movement, Lu Ning pulled at the wound, and he gasped in pain, his eyes suddenly turned red, his face became more hideous, and the curvature of the corners of his mouth was more oblique.

This time, even the Zhao family, who has always protected Liu Xubin, didn't help him, and slapped him, how important his face is to the girl's family!

"How can you make you ...... Brother is injured like this! You manly man doesn't know what to protect! ”

Zhao Shi stood in front of Lu Ning and didn't know where to put his hands and feet, wanting to see her injuries and afraid that his rough hands would hurt her.

Liu Xubin was wronged, he also wanted to protect him, but he didn't have that ability, if it weren't for his sister, he would have been reincarnated.

Lu Ning waved his hand again and again and said that it was okay, really!

By the time Liu Xubin protected her, she would have died five hundred years earlier! He's thankful he doesn't pull her back!

But then again, Liu Xubin really should practice well, a man, how can he cry when he encounters something!

Liu Xubin was shocked by Lu Ning's tiger body, although Lu Ning's deformed face really couldn't distinguish specific expressions, after all, it was too abstract, but Liu Xubin still felt that he was going to be unlucky.

At this time, Lu Ning can be described as miserable, half of her face is swollen like a steamed bun, and her whole face is deformed.

The only problem is that you can't get down if you go up obliquely, your mouth can't be closed, there are small scratches on the corners of your eyes and forehead, your eyes are swollen, and your walnut-like eyes are like a star, not to mention more ecstasy.

How ecstasy?

I'm so ecstatic that I can't tell it's a woman without makeup!

Lu Ning almost fainted when she saw her appearance in the afternoon.

It's been two lifetimes, and it's the ugliest when she was in college military training for a month, but it's far less than one thousandth of what she is now, and the only thing she is proud of now is that her eyes are smaller.

Later, she could only reluctantly comfort herself and say, "It's just right, save cosmetics!" Ugly others, I can't see it! ”

But having said that, she doesn't touch or look at anything that reflects light, including human eyes!

So when Liu Xubin looked at her, she wanted to poke him blind!

The old couple of the old grandfather and Grandma Liu, wiped their tears in distress, and said sorry back and forth, Lu Ning comforted them inarticulately, persuading them to go back, it was not safe to go back when it was dark, but they were still very relieved of Lu Ning, and they couldn't wait to stay, but Lu Ning tried their best to dissuade them, although they went back, but Liu Xubin, who had just returned home and was driven back, was left behind.

It's not that they don't feel sorry for their grandson (son), but they believe in Lu Ning, and Lu Ning is willing to let Liu Xubin go home, which is enough to show that Liu Xubin is not in big trouble now, besides, Lu Ning is a doctor, even if she is injured now, there are doctors around her, it is better for Liu Xubin to stay here than to stay at home.

But Liu Xubin resisted, what is the Mu family? What is the relationship between him and Mu Ruhua?

If you and I are nong, it is better to say, how can he live in this situation now!

But the protest was ineffective, and in the end it was left behind, in the name of "care".

Liu Xubin cried with a sad face, he is still a patient, who takes care of whom!

At this time, Doctor Li came back from Mu Ruhua's side, if Lu Ning hadn't asked him to see it, he wouldn't have got, if he didn't go, the child in Mu Ruhua's womb wouldn't be able to keep the fairy in three days, but now with his intervention, King Yama still has to give him some face, but if he wants to conceive in October, it's a dream, and this child is destined to be a premature baby.

"How? Does it still hurt? Divine Doctor Li lightly poked Lu Ning.

Lu Ning rolled her eyes: "You don't look at where you poked, it was my wound, bleeding, you said it hurts or not, take it away!" ”

Doctor Li was not angry: "What's the matter with your situation, you can discuss it with me now!" ”

Lu Ning sat up with Chunxiao's strength: "It's nothing, it's just that it's more difficult to explain when it comes to the nervous system, okay, okay, I know, you don't have to ask, I'll explain it now!" I'm going to organize the language. ”

But how can this be said?!

Although this involves Lu Ning's profession, it is still difficult for her to explain the structure of the human brain to the ancients.

She thought for a while before she stretched out her index finger and pointed at her head, "Do you know what's in here?" ”

Doctor Li: "Cerebral marrow? ”

Lu Ning nodded: "You can also say that, but to be precise, the human brain is composed of the brain, cerebellum, diencephalon, and brainstem......"

The brain is the highest part of the central nervous system.

It's just that this brain problem has not been thoroughly studied in modern medicine, and Lu Ning can't say it in great detail, after all, this knowledge is very deviant in the eyes of ancient people, so she just simply popularized the knowledge of the brain, such as structure, and focused on explaining the brain's response and processing to pain.

Pain is only a complex brain response, just like a hand is cut, a cut is equivalent to a stimulus, a stimulation of nerve endings, and then the nerve endings feel the stimulation and send signals to the central nervous system, this transmission process requires the participation of multiple neurons in the nervous system, and the brain will further process and act after receiving the information, such as bandaging.

But when the injury is fatal enough to be close to death, the pain is not so obvious, because the brain will take care of the overall situation, instinctively want to live, and will activate CeAga neurons to turn off pain perception to reduce consumption.

It's instinct.

CeAga neurons are central inhibitory neurons, and as long as this neuron can be activated, then pain is suppressed.

The purpose of the deer coagulation needle is also to activate CeAga neurons to turn off pain perception, in fact, general anesthetics can also activate CeAga neurons, but there is a fundamental difference between the two, that is, the difference between being able to act autonomously and general anesthesia.

This was also discovered by Lu Ning by accident, but for various reasons, the technology was not very mature, so that the side effects were very large, so that Lu Ning's nervous system became extremely sensitive when the pain perception was restored, and the wind and grass would stimulate the nervous system, and the pain would be doubled.

She explained it as concretely as possible, but Doctor Li was not a doctor who had studied systematically after all, and he still knew nothing, so Lu Ning had to explain it in more detail, which explained and explained, and a group of people surrounded her, including Li Tingxuan, who didn't want to pay attention to Doctor Li for the time being, and Tu Peng, who Lu Ning didn't want to pay attention to for the time being.

Doctor Li tugged at his beard: "What kind of nerve endings neurons, where did you come up with so many new words." ”

Lu Ning: "......" felt that he had said too much, brainstormed to make up for it, pointed to his head and asked, "This, what is it?" ”

"Head."

"Why do you say it's the head? Isn't it okay to say it's a foot? ”

"Don't you have feet?" Doctor Li patted his thigh.

"Then why do you say feet?"

Doctor Li: "...... Aren't you raising the bar? ”

Lu Ning doesn't think so: "The names we have now have been passed down from generation to generation, no one has delved into why the head is the head, and the feet are the feet, you don't know the structure of the head, what's the point of questioning the name I said?" ”

Doctor Li closed the microphone, because he really didn't know what to call the thing in his head, and he didn't have seen a person whose head was split, and there were white flowers in it, but he didn't know what it was, and he couldn't find a method or case if he wanted to study it, after all, there were really not many people with broken heads and bleeding brains.

Li Tingxuan propped his chin: "So, you made up these names?" ”

Lu Ning looked at him silently, after all, although Lu Ning is swollen now, her face is thin, although she means this, she is still a little embarrassed to admit it so brazenly.

"Then tell me, apart from the brain, what do those cerebellums and diencephalons do?" Tu Yu showed a strong interest.

Tu Peng also pricked up his ears to listen.

As soon as you say a word, I say a word, Lu Ning's rest time suddenly turned into evening cultivation, if she didn't really lie down for a day and didn't want to lie down, she wouldn't be willing to grin to class, her face hurt and she was easy to drool.

But the enthusiasm of the students, Lu Ning is not good at blowing, so that she actually drew the structure of the human brain in this class, and many years of professional made her accidentally draw this human brain vividly.

Lu Ning felt bad after painting, the human brain is not a pig brain or a sheep brain or something, how did she know so clearly, did she pry over other people's heavenly spirit cover or how to drop?

The new term "neuron" is almost impossible to explain, and the human brain ...... Tut!

Just when Lu Ning was thinking about how to explain, Doctor Li looked at the blackboard closely, full of curiosity: "Our eating, drinking, Lazar and sleeping are really controlled by this little thing?" ”

Others are also curious.

Lu Ning breathed a sigh of relief, her apprentices were still very gratifying to her, not only did she be very resistant to what she said, but she was even very curious and interested, it was like a hundred thousand whys, one after another, Lu Ning's speed of solving doubts could not keep up with the speed of asking questions at all.

Oh, as soon as there are many questions, the teacher's mood is no longer relieved, especially in the case of illness, as soon as the small blackboard is closed, Teacher Lu Ning, who has been popularizing science for more than an hour, forcefully announced the end of class.

Moreover, Lu Ning still has some heart congestion, brain surgery, all operations involving craniotomy are precision surgeries, without the assistance of precision instruments, it is almost impossible to complete the operation perfectly and successfully, Lu Ning, a surgeon specializing in brain, has already changed his major at the moment of crossing.

And the students who finished the class didn't know the teacher's mood, especially Doctor Li, who immediately grabbed the small blackboard and got into the house at the moment when Lu Ning announced the end of class, and didn't know what to do.

The three people who didn't grab the small blackboard looked at Lu Ning with blank eyes, but they were kicked out by Lu Ning and Chunxiao.

"I'm really used to them!" Lu Ning muttered.

The teacher can't move, and he still has the face to make such a request! Don't you see that the teacher is in a bad mood now and reminiscing about the past! I don't have any eyesight!
