From troll tribes to elf empires

Chapter 117 Heart, Lungs and Brain

In addition to these hugely different systems, individual organs such as the heart, brain, and lungs, which appear to be very similar in function to the human body in previous lives, are also very different in structure.

For example, the heart has eight internal chambers, two of which form the cardiopulmonary circulation between the heart and lungs, four are used to support the general circulation of the body, and the other two are connected to the cardiovascular system to form the cardiopulmonary circulation.

There are also lungs. Under the huge double lung lobes involved in breathing, two hidden lungs that appear to have degenerated were found.

During further observation, the witch doctors discovered an extremely special organizational structure inside it, and almost overturned the name of "hidden lung".

Hidden lungs are only one thousandth the size of normal lung lobes, and have a large number of densely packed, point-like raised structures on their surface.

Under low-power microscope observation, the witch doctors discovered that these 'bulges' were actually traces of degeneration of blood vessels and other channels.

And made a rough size judgment based on the number, thinking that it should have been an extremely important organ.

After that, the witch doctors cut off a little bit of material from various places where the lung body was hidden, and observed it under a medium- and high-power microscope.

This time, I immediately made a new discovery.

First of all, the troll's hearing is indeed extremely developed. He used to think that this was an adaptation to the dark forest environment, but he did not expect that it also hid the "first-mover" advantage of hearing;

Witch doctors have used many methods to try to activate dormant cells, but all ended in failure.

Of course, this is only the most rough division. In fact, each part can be further distinguished, such as various small organizations that are independent in structure, but their specific attributes cannot be ascertained at all.

Through this connection, they barely maintain their only vitality by relying on some waste gas that should have been eliminated from the body.

However, in fact, this function has been usurped by the midbrain, which is only responsible for the 'auditory information summary center', and has become the general base for all the 'feelings' of today's trolls.

The first one is the parietal brain, which is an extension of the midbrain and is almost the most developed primary sensory processing center in the brain today.

Among them, the forebrain proliferates forward and upward to form the telencephalon; the midbrain proliferates upward to form the parietal brain; the hindbrain proliferates backward and upward to form the posterior tectum.

Almost all cells in the hidden lungs are in a semi-dormant state after extreme contraction.

The content is the differentiation of brain regions that they have just completed after going through a lot of hard work.

Closer to home, when other groups had submitted interim reports several times, the witch doctors of the brain group shyly handed in the first results.

Usually the cells closer to the outer wall of the tissue, such as body surface skin, oral mucosa, hair, etc.;

Or the interior of organs that may be exposed to external substances, such as the lung cavity, retains extremely strong fire resistance.

As for the remaining cells, although their fire resistance has degraded to varying degrees, they still retain minimal traces.

Not only that, the midbrain has also formed a 'motor response' connection with the posterior tectum, taking over the function of 'permitting movement', allowing the posterior brain to shrink at the bottom of the brain, only responsible for the operation of some 'non-active muscle groups', and

There are other basic functions that are not yet understood.

They believe that the trolls were originally a special kind of life that was born in the volcanic magma lake. After a long evolution, they gradually climbed up the 'shore' and became what they are today.

When judging the functions of brain areas, witch doctors adopted sensory restriction methods and local anesthesia. Through two-way manipulation of the body's sensory system and brain areas, they initially achieved the purpose of understanding the functions of each area.

If this characteristic had already appeared during the "volcanic period", it would undoubtedly be a problem for the traceability work, because there may be no way to leave fossils before and after that period.

They first made structural distinctions in the brain by dissecting cadavers, and initially distinguished the forebrain, midbrain, hindbrain, medulla oblongata, and their respective derived structures in the center.

This result, which is almost 1 greater than 2, is undoubtedly the contribution of the troll's first-mover advantage in hearing, which has reduced the forebrain to the 'worker' of the midbrain.

Blade Ya thought about it carefully and found that he could also faintly feel this clue in his life.

In addition, the troll's fire resistance also has a very strange manifestation, that is, it is only reflected in living bodies;

When a troll dies, it loses this ability very quickly, so it has the characteristic of being cremated.

Of course, the focus of this research is not 'archaeology', and the witch doctors are not too invested in this conjecture. It is more of a conversation topic during breaks.

This hypothesis is recognized by most witch doctors, because they have found a certain degree of fire resistance when observing the cells of any tissue in the body.

These cells maintain minimal communication with other circulatory structures in the body through capillaries.

However, compared to the reactions of other creatures when faced with fire, this kind of damage is still not severe enough, so it can be regarded as a residual trace of fire resistance.

For example, when a troll cuts off a limb, although the flames will cause damage to the muscles and blood in the wound, it may even cause necrosis in severe cases. Only by gouging out the corresponding part can it regenerate.

These observations have become important support for the ‘volcanic origin theory’.

In terms of experimental methods, the brain team chose the plan of ‘anatomy on dead bodies and determination on living bodies’.

Later, combined with the various differences between the troll body and other creatures, the hypothesis that "trolls originated from volcanic magma" was further made.

This discovery gave the witch doctors of the research team great inspiration and put forward the hypothesis that "troll life may originate from areas without normal air."

In addition, from a functional point of view, the forebrain, which is responsible for the "aggregation" function of "vision and smell", should originally have the advantage of competing for the "sensory center";

For example, the front tectum processes vision and smell, the lateral brain processes hearing, and the posterior tectum controls the motor system.

He also made the judgment that "trolls should have been auditory creatures at the beginning" and gave the relevant basis.

Secondly, 'hearing' seems to really make it more pleasurable in terms of perception than sight and smell? Just like in bed, sound can make it feel more satisfied than body posture.

Maybe it's related, maybe it's not related, these kinds of thoughts may be just subjective misjudgments of Blade Ya and cannot be used as a real basis.

Moreover, the research team's methods for studying the brain are still too crude, and the information and conclusions it obtains are mixed with too many guesses and associations.

Therefore, it remains to be judged further in the future as to what the facts are.

It’s another full day of classes, and my head is feeling dizzy.
