THE UNKNOWN FACTS

15 THE UNKNOWN FACTS

1.The adult brain contains around 100 billion neurons and even more

support cells.

2.Your brain uses less power than your refrigerator light –just 12 watts.

3.There is no pain receptors in the brain. so, the brain surgery or injury can occur without causing pain. The scalp and skull, however, is sensitive to pain.

Receptors-A specialized cell or group of nerve responds to sensory stimuli (Motives).

4.The total length of myelinated nerve fibers in the brain is between 150,000 and 180,000 km. Which is enough to go around the Earth nearly four times.

The main purpose of myelin is to increase the speed at which electrical impulses propagate along the myelinated fiber

5.Your brain accounts for just 3 percent of your body’s weight but, it consumes 17 percent of your body’s total energy.

6.Losing a gene can be a good thing. It may make us less likely to suffer from sepsis.

7.Research suggests that aspirin protects men against heart attack but not stroke, yet it protects women against stroke but not heart attack.

Aspirin- A chemical compound used to treat pain, fever, and swelling.

8.Women wake up from anesthesia nearly twice as fast as men.

9.A 20-year-old obese man can expect to live for 13 years less than average life span.

10.Research has found that people tend to correlate sweet and sour tastes with high-pitched sounds and savory (delicious) and bitter tastes with low-pitched ones, and that people enjoy food more when ‘matching’ music is played during eating.

11.A man makes 1500 sperm per heartbeat.

12.Advances in nanotechnology has facilitated the creation of miniature machine parts made from DNA. It might be possible to use these to fix damaged cells.

13.Scientists have used carbon nano-tubes and enzymes to create an antimicrobial coating that can kill MRSA within two hours of application. This could be used to paint the walls of hospitals and sterilize equipment.

MRSA- Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium that causes infections in different parts of the body and it's resistant to some commonly used antibiotics.

Enzymes- In human chemistry, an enzyme is a protein manufactured by a cell, and it is also known as a catalyst. For example, enzymes help break down larger molecules of starch, fat, and protein during digestion.

14.Scientists have created a nanotechnology-based therapy that can help to repair brain damage and partially restore the eyesight of blind animals within a few weeks.
