Rebirth of the Supreme Ice King

Chapter 934 Anatomy of the Brain
"That's right, the department you talked about should be more clear than the general explanation you just gave, and it will only make it easier for them to understand." Xin Yu said.

"The brain is the most advanced part of the nervous system. It is composed of the left and right cerebral hemispheres. There are horizontal nerve fibers connecting the two hemispheres. Each hemisphere includes: Cerebral cortex: It is a layer of gray matter on the surface. The surface of the human brain has There are many concave grooves, and there are bulges between the grooves, thus greatly increasing the area of ​​the cerebral cortex. The human cerebral cortex is the most developed and is the organ of thinking. It dominates all activities in the body and regulates the relationship between the body and the surrounding environment. balance, so the cerebral cortex is the material basis of advanced neural activities,

The brain mainly includes the left and right cerebral hemispheres. It is the largest and most complex structure in the central nervous system, and it is also the highest part. .The surface of the cerebral hemispheres presents different grooves or fissures.The raised part between the groove and the fissure is called the gyrus.The cerebral hemispheres are divided into 5 lobes by grooves and fissures: the frontal lobe, temporal lobe, parietal lobe, occipital lobe, and insula. "

"Wow, wait, wait, what you said is too detailed, it is really hard to understand, can you explain it in the most common words? This is too much, written language, philosophy , I think, if you speak it in the most common words, they should understand better, I feel that they are completely confused now." Ling Wei said, he listened to it and said a lot here, completely I don't know what I'm talking about, I can't understand it at all.

"But everything I'm saying now is the most popular and most popular words. After all, I still can't change the names of some professional terms. Why don't you let me explain them to see how much they can understand?" Let it be said.

"OK then."

"The surface layer of the cerebral hemisphere is gray matter, and the deep layer is the medulla. The medulla contains nerve fibers and nuclei, of which 4 pairs of nuclei are located at the bottom of the brain called the basal ganglia, including the caudate nucleus, lenticular nucleus, amygdala and claustrum Nuclei. The caudate nucleus and the lenticular nucleus are also called the striatum. Damage to the striatum will cause chorea and tremor paralysis, increased muscle tension throughout the body, slow movement, etc. The white matter in the hemisphere has various orientations, such as the commissure The fibers of the left and right hemispheres connect the fibers of the same hemisphere, connect the cerebral cortex with the brainstem, and the ascending and descending fibers of the spinal cord. The latter must pass through the internal capsule. On the horizontal section of the brain, the internal capsule is a thick white matter layer , divided into 3 parts, namely, the front foot of the internal capsule, the rear foot of the internal capsule and the genu of the internal capsule. Each part has a corresponding fiber bundle passing through. Injury to the internal capsule can cause hemiplegia, deviation of voice and loss of partial body sensation. The inner part of the cerebral hemisphere The cavity is called the lateral ventricle and contains cerebrospinal fluid.

That’s about it. Although it’s a bit difficult to understand, think about it carefully. I’ve explained the entire appearance of the brain, including its interior. The resemblance or very similar things mentioned just now are where the brain is located. Don’t be too anxious, and you must not dig into the horns, just feel it slowly. After all, these things will not be successful in a while. It is also my problem that what I just said is too general. If you feel the brain, just tap it lightly and vote for me. I will explain the central nervous system to you next, okay? "It's natural to say that now these things are completely dependent on it. As the only psychic, he must not be messed up, and he must take his time. He can't lead others astray, and he can't be in a hurry.

"Perhaps you can talk to him in a more popular and understandable way. Compared with scriptures, these very theoretical knowledge are really difficult to understand, especially when you are completely concentrated and don't have the mind to analyze what you have learned. What do you mean by every sentence you said? So, why don’t you explain it to them a little bit.” At this moment, Cheng Cheng said, “I can feel that the breath of the three of them is very chaotic. It may be that you are a little anxious. After all, you have said so much just now. They haven’t found any clues yet, so they are a little anxious. You can persuade them now. Don’t be too anxious, because you also Didn’t you say that if you are too anxious, you will not succeed, so it’s better for you to persuade them.”

"Well, let me tell you in general now. I told you that the brain is divided into two parts. It is composed of the cerebellum and the brain. You only need to feel an oval-shaped object like this, and The message that this object is constantly sending is the brain, do you understand? I feel that what I have said is enough, and you must have understood it, right?" Be patient, after all, he has already said a lot of things, very detailed, very detailed, but they haven't understood yet, which makes Youran feel a little helpless, but he can't say it, after all, everything is in the Rely on it, if they don't break this illusion and no one leaves the illusion and no one can see the real world, they may be trapped in this environment forever. Although he can leave this illusion naturally, but he leaves this illusion It’s useless to let Lin Ye, Li Jie, and other epic-level supernatural beings leave the illusion, and then see what it’s like to really exist in the real world. Have you noticed whether there is any danger around here? If there is danger, you must immediately.

At this moment, Lin Ye, Li Jie, and the Man-faced Spider Corpse King nodded at the same time, which showed that they felt the existence of the brain. It was really not easy, and they were very happy because of it.

"Wow, they seem to have understood. They all nodded just now, which means that they have already felt the position of the brain. It is really not easy. This is really difficult to understand, but they I really appreciate the understanding." Ling Wei said.

"Now let them consolidate the position of the brain again? Then you can talk about it later, and explain the central nervous system to them later. I feel that they may still be in a relatively confused stage, so don't be too anxious. Go on and let them understand a little bit first, after all, I said a lot of things just now, even if they feel it now, they are still a little confused." Xin Yu said.
