Where are the wonderful animals, broken eggs accompany you to the end~
Woodpeckers, the "little warriors guarding the forest", hunt the pests inside the trees by knocking on them. So the question is, how does it do to knock crazy without fainting? Will it cause a concussion if you keep knocking it like this?
This bird brother, you calm down, calm down

After all, it was a human being, under such a violent impact, the brain must have been severely concussed, even if there was a resurrection card, it would not work. Coincidentally, scientists are also very curious about this problem, and through research, they have explained its behavior, and look down with the broken egg.
< h1 class= "pgc-h-center-line" > a precise skull structure</h1>
Woodpeckers are able to get dizzy under violent impacts, and the delicate skull structure is certainly inseparable. Don't look at its small head, in fact, its head structure is still very precise, the thick skull is wrapped in a spongy cavity; the sponge cavity contains a bundle of trabecular fibers; the base of its beak contains a cartilage buffer system, which can ensure that it can alleviate concussion when pecking insects; the narrow arachnoid membrane hardly contains cerebrospinal fluid, but has a strong network of veins to protect the eyes.
< h1 class= "pgc-h-center-line" > uneven body proportions</h1>
As far as the proportion of the woodpecker's body is concerned, its body is large and small, and it is precisely because of this body proportion that its head bears a much smaller impact, because the area of the brain is small. When they are impacted, most of the force will be dispersed to the body, although it is quite heavy when watching them hammer down, this brother really does not take himself seriously, so hard.
<h1 class="pgc-h-center-line" > precise control</h1>
Don't look at the woodpecker is always pecking, pecking, pecking, but in fact, every stroke of it can hit the wood with precision. In the process of pecking at the tree, the strong muscles of the woodpecker contract a second before the impact, thus forming a very tight cushion, thus transmitting the impact force to the lower and rear of the skull, perfectly avoiding the brain.
And before hitting the tree, its thickened instantaneous membrane will automatically close, so that before hitting it, its thickened instantaneous membrane will also close, which not only prevents the eye from jumping out, but also avoids debris from hurting the eye; the ctenophore can prevent the eye from running out, and can also increase the pressure on the brain to maintain a similar structure of the retina in its original position.
< h1 class="pgc-h-center-line" > tongue shock absorber? </h1>
The tongue of the woodpecker is the most interesting, because even those great men cannot put it down at the last moments of their lives. Its tongue can really be described as a rare "strange thing" in the animal kingdom, "strange" to that extent, first look at this picture to feel it.
What's the point, right, its long tongue, growing to that extent? It went around the skull, and yes, it was a circle. Even if it starts from the maxilla and then from the right nostril (left breath?). It came out inside, then passed through both eyes, and then the fork went round the back of the skull in the direction, around the whole brain and back from the sides of the neck, and then merged into one through the mandible and extended out.......
At the beginning, the painting style is still quite normal, how come the more wrong it is to the back, and a tongue completely bypasses the entire brain? This is because the woodpecker's tongue has a very strong toughness, and after a week of circling the head, it is equivalent to adding a "seat belt" (shock absorber) to the entire brain, which greatly absorbs the vibrations generated and protects the woodpecker's brain.
This tongue, I am convinced
How, is not these "designs" to shatter the three views, to prevent the broken egg in the hands of the bread is not fragrant, the use of tongue as a reducer also thanks to the woodpeckers to think of, but this is the world is no wonder.
