Why is the left and right hands and the brain cross managed?

This is the characteristic of the distribution of the human nervous system, each part of the brain manages different aspects, the nervous system is divided into receptors - afferent nerves - central - efferent nerves - effectors, sensory nerves and motor nerves cross in the spinal cord.

Yes, the left side of the brain manages the right side of the body, nerve commands, etc., and the right side vice versa.

No one knows at the moment, and knowing it solves the problem of human evolution.

The human brain has cross-control over the limbs. That is, the left brain dominates the right hand, and the right brain dominates the left hand.

Hehe, the landlord is left-handed, just like me. Most people have a well-developed left half of the brain, and the right hand is more comfortable to use; We have a well-developed right half of the brain, and the left hand is smoother to use than the right hand.

People who are accustomed to writing with their left hand are generally smarter because the right side of the brain is associated with the left half of the body. The left side of the brain is associated with the right hemisphere.

What did you ask about left-handed handwriting? Does it mean that you can use both left and right hands?

The hemispheres of the human brain are cross-controlled, that is, the right side of the brain controls the left half of the limbs, and the left side of the brain is vice versa. There is a different division of labor between the left and right brains, and it can't be said that we don't care about the left brain if we develop the right brain without limit, and the left brain of normal people is more developed, but the right brain of artists is more developed, for example, the general string instruments are the left palm strings, according to scientists, the right brain of the human body stores 10w times the amount of information of the left brain. The human brain is not fully developed, because longevity is 100 years.

Just try to develop the right brain as much as possible.

In fact, there are many ways to develop the right brain, not only left-handed writing, for example, we can use the mouse with the left hand, use chopsticks, exercise, table tennis, badminton, etc. Let's study it slowly, there are still a lot of benefits, and if you can practice the kung fu of playing left and right, then you will be really good.

The left and right hands of the human being are under the command of the right brain, what you call left to right, right to left, that is, the upper limbs of the human body are crossed in the projection part of the brain, that is, the place where the brain manages the left and right hands is left to right, right to left.

Theoretically, yes. A person's left hand is controlled by the nerves of the right brain, and generally speaking, left-handed people are smarter than normal people!

yesMove your left hand more to flex the cerebellum, have you found that the left-sided ideas around you are quite unusual! Quack

Not exactly, the right brain directs only a part of the function.

Yes, the right brain controls the left hand and the left brain controls the right hand.

Not necessarily, but exercising your left hand can make your brain develop again.

There is such a saying in Chinese medicine.
