It does not matter if you are rich, poor, young, old, sick, healthy, or different. Everyone in the world has a natural set of values. Some of the behaviors include a set of situations. Scientists continue to explore the purpose of these interests and develop ideas in their work. Most organized emotions are a mystery of evolution. In this article, I focused on the thinking of adults and left the common sense of the past.
The old reflex is expressed by normal human infants and not mentally mature adults. Other examples include the Palmar grasp reflex, a practice for infants to close their hand at anything that touches the hand. A swimming reflex occurs when you put a small baby in the water. In response, they will begin to grow and kick. Until they are four months old, the baby will turn its head to anything that rubs its cheek or mouth. This is known as the reflex and is used to help with breastfeeding.
3. Yawning
Yawning is a human instinct. It involves sniffing the air, stretching the ears, and following a large exhalation. Yawning is associated with fatigue, stress, lack of motivation, and boredom. He is one of the most extraordinary human works. Yawning can be infected and caused by seeing others yawning, hearing yawning, or talking on the phone with someone trying. Numerous ideas have been proposed to try to explain why animals roar, but none have been proven. One theory is that when human blood contains elevated amounts of carbon dioxide and requires oxygen, yawning is heard. However, some studies show that yawning reduces oxygen intake. Another theory is that yawning is a human way of controlling brain temperature. It has been suggested that yawning may reduce or increase blood pressure in the brain. This view has been supported by the fact that people desire to yawn while making major elevation changes. Another thought-provoking factor is the desire to stretch one's muscles. Infected yawning can be a way to keep a group of animals awake. It can be a natural reaction from one herd member to the next, reminding everyone to stay alert. Anecdotal evidence suggests that yawning helps increase the level of alertness. When animals are seen yawning, the human response is to know the creature's teeth and the ability to fight.
2. Vestibulo-Ocular Reflex
Have you ever wondered how people can move their heads from left to right but focus on visual images? The vestibule-ocular reflex (VOR) is a movement of the human reflex that stabilizes images in the retina. It accomplishes this by producing rapid eye movements in the opposite direction of the head movement. For example, when a person's head moves to the right, the eyes turn to the left, and vice versa. VOR is important because people always make small head movements. People with non-disabled VOR often cannot read because small head movements obscure the image.
VOR works in complete darkness even when the eyes are closed. It is estimated that eye movements slow down the movement of the head by less than 10 milliseconds. Today, doctors can diagnose VOR with a caloric reflex test, which includes injecting cold water, warm water, or air in the ear. When you put water in the ear, VOR is automatically triggered. A healthy cerebellum is also important for VOR to ensure accurate eye movement. People who experience brain damage to the cerebellum often have complex problems with visual perception.
Fascinating Truth: Have you ever wondered why you should not drink and drive? Consumption of ethanol (alcohol) can interfere with VOR, greatly reducing your vision. The more you get drunk, the more blind you become.
1. Mammalian Diving Reflex
The mammalian diving reflex allows people to stay underwater for longer periods of time. It is strongly expressed in aquatic mammals but also in humans. Reflex diving is done, especially when cold water touches the face. Water warmer than 21 ° C (70 ° F) does not irritate, nor does immersion. As soon as the face hits the cold water, the diving reflex increases oxygen release. A person's heart rate decreases by 10-25% and blood flow are limited. At extreme depth, the body deliberately allows fluid to fill the lungs and chest cavity to protect the organs from pressure.
The reflex of mammalian diving greatly increases the chances of survival during accidental immersion. It helps prevent drowning in people and also works if a person is unconscious before entering the water. Because of its appearance, a person can live longer without oxygen in cold water than on dry land or in hot water. Another interesting fact is that the diving reflex decreases as you get older. Babies often survive for a long time in cold water. The reflex is extreme for signs, otters, and dolphins, which are mammals that spend a lot of time in the water. It remains unclear whether the diving reflex comes from a frigid climate without water.
Fascinating Fact: The mammalian diving reflex has led some to explore the concept of water monkeys, which the common ancestors of modern humans spend time accustomed to underwater life. The hypothesis is based on the differences between humans and other large monkeys and similarities between humans and other aquatic mammals. This concept uses many human activities to support claims that include hair loss, hair loss, lower extremity fat in children, lower larynx, nasal congestion, voluntary respiratory control, waxy covering in newborns, and mammalian diving reflex.
