You might be surprised to discover some things you did not know about your own body. In fact, you might think some of those amazing things cannot be truth. However, through research everything written in this article is true to the best of this writer's knowledge.
When you get out of bed in the mornings, you are a wee bit taller than you were when you went to bed the night before. That's because pressure is put on your joints during the day as you go about your daily activities. The pressure causes the cartilage in your spine to compress enough to push everything down during the day. While sleeping, that pressure on your spinal disks allows you to return to your full height.
After people have been dead for a while, their bodies turn into a skeleton. What people might not know is that while living, everybody gets a skeleton every ten years. If you are 70 years old, you have had seven skeletons during your lifetime.
About Your Bones
Your bones are stronger than a piece of steel. The strongest and longest bone in the body is the femur. It is your thigh bone, and it takes a lot of force to break it because it can support up to 30 times your weight.
According to Mammal Anatomy: An Illustrated Guide, people are born with about 300 bones. By the time a person reaches adulthood and stops growing, his body has only about 206 bones.
There are 27 bones in each hand. One-third of the bones in your body are found in your feet. There are 26 bones in each foot with 33 joints and over 100 muscles, tendons, and ligaments. That means that more than half of the bones in your body are in your hands and feet.
The smallest bone is shaped like a stirred in your middle ear. It has a base and an oval window. The bone is covered with a membrane that measures sound vibrations.
Your Largest Muscles
According to the Library of Congress, your rear end has your largest and strongest muscles. The muscles move your hips and thighs to work against gravity to keep you walking upright when you go uphill and upstairs.
When researchers in Meridia Huron Hospital tested the effect gastric juice has on metal objects, they found that within 24 hours, the stomach acid had reduced razor blades to 63 percent of their original weight.
If your small intestine is uncoiled, it will be four times as long as you are. That's because it is about 18 to 23 feet long.
The network of neurons that lines the gut is referred to by scientists as "your second brain." Other than aiding in your digestion, your gut comes with its own reflexes and senses that work along with your nervous system. That's why people say, "Trust your gut" or "Go with your gut."
Your stomach growls when you are hungry because of the mixture of fluid and gas moving around in your intestines.
All adults have something that babies don't have. Babies are not born with kneecaps. Their cartilage gradually turns into bone, and kneecaps begin to develop when the child is between two and six years old. Kneecaps aren't fully developed until the child reaches young adulthood.
Most of the strength of your hand is in the pinkie, your smallest finger. The pinkie helps the other fingers to function. Half of the strength in your hand is in your pinkie.
There are no muscles in your fingers even though you can do many things with them. The movement of your fingers is due to tendons and bones, not muscles. There is help from the muscles in the palms of your hands.
About Your Ears
It is annoying to have earwax in your ears. However, earwax is actually good for your ears. The wax lubricates the ears, cleans them and protects them from infection.
Earwax is 50 percent fat that coats the ear and catches dust and debris. Earwax might be annoying and looks gross, but it keeps the ears healthy.
We blink about 15 to 20 times per minute. Blinking is necessary to keep your eyes moist. Researchers at Washington University discovered that blinking can help sharpen attention and give your body time to recharge. It is understandable while a blink is called a "micronap."
Big eyes are beautiful, but they can be the cause of nearsightedness, known as myopia. That condition causes distant objects to look blurry because light doesn't properly reach the retina.
The most obvious signs of Alzheimer's disease is forgetfulness and memory loss. However, dementia also manifests itself in a person's eyes. According to a 2019 study published in Neurobiology of Aging, researchers discovered that individuals with cognitive impairment who are at risk of developing Alzheimer's have greater pupil dilation while performing cognitive tasks.
Not Two Bones
Your tongue is the only muscle that doesn't join two bones. In every other part of your body, muscles connect to bones at both ends. Your tongue is connected to your hyoid bone, which is part of your neck. However, nothing is on the other side of your tongue.
Your Tongue Print
You know your fingerprint is unique. Did you know that you have a unique tongue print also? Well, you do have one-of-a kind tongue print that is different from anyone else's.
A 2016 study by the Thai Moogambigai Dental College compared individual shapes and textures of tongues. They discovered that no two tongues are exactly alike. They are different even in twins.
Like hearing and seeing, your sense of taste decreases as you age. It also diminishes after sickness, an injury or after taking some medicines. Women usually experience a decrease in their taste sooner than men. Women begin to notice a change in their 50s. Men don't experience a change in their taste buds until they are in their 60s.
It is interesting that humans have chins but animals don't. Even though you have pets, you probably have never noticed that they have no chin. They do have jaws but no chin.
Have you noticed that you have to trim your fingernails and toenails more often than you used to? It is not your imagination because nails grow faster today than they did in the past. A 2010 study at the University of North Carolina compared the growth of fingernails and toenails to studies done 50 to 70 years ago. They found that growth had increased by almost a quarter over the decades.
The nails on your big toes grow more than 2mm per month, compared to 1.65mm per month in the 1930s. Researchers thinks the reason is because of the rising increase in protein-rich diets.
The American Academy of Dermatology (AAD) says a fingernail takes around six months to grow from base to tip, and toenails can take up to a year to grow that length. The AAD also reported that fingernails grow faster on a person's dominant hand, as well as on the bigger fingers. They also grow faster during the daytime and during the summer months
Your nose has two nostrils, but they do not work simultaneously. Your nostrils do not share the workload for you to inhale and exhale. You breathe through only one nostril at a time.
According to the results published in the journal Mayo Clinic Proceedings in 1977, one nostril takes a break while the other nostril takes over and does all the work. After a few hours, the nostrils switch places. If you think this is unbelievable, test it by putting your finger under your nose and find out that this is absolutely true.
About Your Hair
You Are Hairy
You might find it strange to find out that your body is just as hairy as chimpanzees. You have just as much hair per square inch as chimps. You can't see that much hair on your body because the hair is much finer, according to a 2011 paper published in the International Journal of Trichology.
Hair Can Detect Bitter Tastes
Nasal passages and lungs are lined with fine hairs that detect and sweep out impurities. Hair can detect bitter tastes passing through them such as nicotine. The hairs increase their rate of movement to sweep out the bad stuff.
Hair Tracks Your Sleep
Your hair knows when you are asleep and when you are awake. It can track your sleeping patterns. Researchers at Yamaguchi University discovered in 2010, that hair follicles can track the body's clock and knows about a person's sleep and wake cycles. Your hair can detect if you go to bed late or if you get up early.
Hair Helps the Environment
According to environmental engineers at the Missouri University of Science and Technology, dirty hair can be good for the atmosphere because it absorbs the air pollutant ozone. Scalp oils contribute to this.
A person's skin can indicate if a person has high cholesterol that can lead to a heart attack and heart disease. Uneven yellow patches called xanthelasma can appear on the eyelid and around the eyes as a result of overproduction of cholesterol, according to the American Osteopathic College of Dermatology (AOCD).
Your blood makes up 8 to 10 percent of your total body weight. Hematologist and oncologist Daniel Landau, MD, explained that the average adult has about 1.2 to 1.5 gallons of blood in their veins. However, a baby has barely any blood when it is born.
Dr. Landau, says it's typically for babies weighing 5 to 8 pounds to have no more than one cup of blood.
It might not be surprising to some people because they already know that the liver grows back to its normal side even if it is reduced by as much as 75 percent. This can happen within a month, according to the University of Iowa.
Have you ever wondered where the fat goes when you lose weight. It doesn't disappear in thin air. Most of the fat you lose leaves your body through your lungs. About 84 percent is converted into carbon dioxide and leaves your body through your lungs, according to the British Medical Journal. The remaining 16 percent is converted to water, which exits your body through sweat, tears, and other bodily fluids.
