One god gifted thing we can never ignore. In fact it is the most delicate 'machine' ever made. Unfortunately even with our deepest knowledge we could not replicate this 'machine'. Human body! Our body is full of mysteries and things we might never know about, in our entire life, so here a few things you probably didn’t know about yourself.
10 Body Position Affects Your Memory
Can’t remember your anniversary, hubby? Try getting down on one knee. Memoriesare highly embodied in our senses. A scentor soundmay evoke a distant episode from one’s childhood. The connections can be obvious (a bicycle bell makes you remember your old paper route) or inscrutable. A recent study helps decipher some of this embodiment. An article in the January 2007 issue of Cognitionreports that episodes from your past are remembered faster and better while in a body position similar to the pose struck during the event.
9 Bones Break (Down) to Balance Minerals
In addition to supporting the bag of organsand musclesthat is our body, boneshelp regulate our calcium levels. Bones contain both phosphorus and calcium, the latter of which is needed by muscles and nerves. If the element is in short supply, certain hormones will cause bones to break downeupping calcium levels in the bodyeuntil the appropriate extracellular concentration is reached.
8 Your Stomach Secretes Corrosive Acid
There’s one dangerous liquid no airport security can confiscate from you: It’s in your gut. Your stomachcells secrete hydrochloric acid, a corrosive compound used to treat metals in the industrial world. It can pickle steel, but mucous lining the stomachwall keeps this poisonous liquidsafely in the digestive system, breaking down lunch.
7 Thousands of Eggs Unused by Ovaries
When a woman reaches her late 40s or early 50s, the monthly menstrual cyclethat controls her hormone leveland readies ova for insemination ceases. Her ovaries have been producing less and less estrogen, inciting physical and emotional changes across her body. Her underdeveloped egg follicles begin to fail to release ova as regularly as before. The average adolescent girl has 34,000 underdeveloped egg follicles, although only 350 or so mature during her life (at the rate of about one per month). The unused egg follicles then deteriorate. With no potential pregnancy on the horizon, the braincan stop managing the release of ova.
6 Cell Hairs Move Mucus
Most cells in our bodies sport hair-like organelles called cilia that help out with a variety of functions, fromÂ digestionto hearing. In the nose, cilia help to drain mucusfrom the nasal cavity down to the throat. Cold weather slows down the drainingprocess, causing a mucus backup that can leave you with snotty sleeves. Swollen nasal membranes or condensation can also cause a stuffed schnozzle.
5 Big Brains Cause Cramped Mouths
Evolutionisn’t perfect. If it were, we might have wings instead of wisdom teeth. Sometimes useless features stick around in a species simply because they’re not doing much harm. Butwisdom teethweren’t always a cash crop for oral surgeons. Long ago, they served as a useful third set of meat-mashing molars. But as our brains grewour jawbone structure changed, leaving us with expensively overcrowded mouths.
4 The World Laughs with You
Just as watching someone yawncan induce the behaviorin yourself, recent evidence suggests that laughteris a social cue for mimicry. Hearing a laugh actually stimulatesthe brainregion associated with facial movements. Mimicry plays an important role in social interaction. Cues like sneezing, laughing, cryingand yawning may be ways of creating strong social bonds within a group.
3 Your Skin Has Four Colors
All skin, without coloring, would appear creamy white. Near-surface blood vesselsadd a blush of red. A yellow pigment also tints the canvas. Lastly, sepia-toned melanin, created in response to ultraviolet rays, appears black in large amounts. These four hues mix in different proportions to create the skin colors of all the peoples of Earth.
We know that hormone-fueled changes in the body are necessary to encourage growth and ready the body for reproduction. But why is adolescenceso emotionally unpleasant? Hormones like testosteroneactually influence the development of neurons inthe brain, and the changes made to brain structure have many behavioral consequences. Expect emotional awkwardness,apathyand poor decision-making skillsas regions in the frontal cortex mature.
1 Much of a Meal is Food For Thought
Though it makes up only 2 percent of our total body weight, the braindemands 20 percent of the body’s oxygen and calories. To keep our noggin well-stocked with resources, three major cerebral arteries are constantly pumping in oxygen. A blockage or break in one of them starves brain cells of the energy they require to function, impairing the functions controlled by that region. This is a stroke.
