Secrets of the human body that scientists have not yet solved
Human body secrets that scientists have not yet solved
The human body is a real miracle in all respects, and scientists have been able to discover a lot about the human body and its working mechanisms, but there are some secrets of the body that seem to some automatic and simple movements, but in fact, scientists have been unable to explain the reasons for these phenomena so far, and from these phenomena:
Yawn
We yawn when we feel sleepy, when we are bored, and when we see someone else yawn. In fact, we all know when we yawn, but no one even scientists knows when we yawn?
In the past, people thought that yawning was an involuntary movement of the body, with the aim of getting more oxygen in the blood, but this theory was later ignored, and Dr. Gordon Gallup, Professor of Psychology at the University of Albany, believes that yawning is the body’s way of dealing with a high temperature. Brain heat, as it is cooled by yawning. Gallup believes that things that make us yawn, such as the desire to sleep, cause the brain to heat up. When we yawn, cold blood is pumped from the heart, reaching the brain, in which case the hot blood in the brain is replaced by cold.
However, scientists are fully confident that yawning is one of the most primitive functions that humans perform. Fetuses yawn during the first three months in the womb. Darwin linked humans and animals in his theory through yawning, as animals also yawn, and some have claimed that Yawning was a means of communication between Neanderthals before they knew language and speech, and until now, scientists have not been able to develop a logical explanation for yawning.
Appendix :
The appendix is a small tube about 3.5 inches long inside our body, and there are between 1 in 15 people who are exposed to the removal of this appendix, but so far scientists have not understood the significance of the presence of this appendix, but Professor Lauren Martin, professor of physiology at the University of Oklahoma, believes that the appendix serves Some vital functions in the human body, such as the production of some compounds that maintain the health of the body, and help the fetus grow, but so far there is no evidence of the correctness of Martin’s words.
blushing
Charles Darwin, the author of the theory of evolution, said: “Blushing is the most bizarre and most humane expression of mankind.” The face, however, the redness of the face is still a dilemma facing human physiologists and psychologists. We know what the redness of the face is, but we do not know why this condition occurs.
Right hand writing:
We know that most people write using their right hand in writing, and we all noticed while we were in school that there are a few different people who use their left hand in writing, and until this moment scholars have not been able to reason why the right-handed trait is prevalent in writing, and this trait is It cannot be predicted for fetuses by knowing the genes of the parents.
Some scholars believe that the use of the left hand may be caused by trauma to the brain during childbirth, but so far there is no explanation for the phenomenon of the predominance of the use of the right hand instead of the left
dreams:
When we dream we can travel around the world and in the seven seas and perform miracles, but despite that we still do not know why we dream, and there is no universally accepted definition of what a dream is, and Sigmund Freud suggested that dreams are a representation of our hidden desires, and there is another hypothesis that says that dreams It represents a state of facing the fears that we encounter in daily life. Some psychologists believe that dreams regulate our mood in the long term or that they are a way of regulating our daily memories.
Awareness :
Awareness or cognition in humans is really the biggest mystery in life, it holds in the gem of the secret of life, and it is certain that some scientists have discovered that consciousness results from nerve signals that occur in the brain, but this mechanism does not tell us much about the meaning of consciousness.
