  1. Brain stores information equal to 500,000 Encyclopedia Brittanica..Given its comapact size and low power consumption and massive storage capacity it can work better than any computer
  2. 74.418 km of nerves send impulses as rapidly as 360 km per hour..The fastest nerve impulse travels at 532kmph
  3. If you lose blood flow to the brain you will last around 10 seconds before you pass out
  4. your brain never loses it ability to learn because  its constantly rewiring itself
  5. contrary to the local myth,our brain is not capable of multi tasking
  6. Brain is not capable of concentrating for a longer peroid of time,therefore it is advisable to take mini breaks in between long lectures

Muscles are like engines and there's no way we would be  able to do anything without them..Even though it might be different in function from a car engine,its basic function remains the same,translating energy into motion.. It is layers of protein tissues sliding over one another..Muscles can contract and relax..The total number of muscles in our body is 630..It takes 17 muscles to smile and 42 to stare..The largest muscles is the buttock muscle andthe smallest muscle is the stapadius muscle. .Goosebumps are because of muscles present at the root of the hair...The hardest working muscle is that of the eye..Thumb and fingers dont have any muscles..Hand has 20 different muscles..Muscles account to 40% of your body weight.It takes around 72 muscles to talk

  1. eyes
  2. ears
  3. nose
  4. tongue

They connect us to the outside world.Human sense organs contain receptors that relay information back and forth to the brain.


Our ears can detect 1500 different tones,350db of loudness.,but nobody  knows how the brain tells the difference between high pitched and low pitched sounds..The smallest 3 bones are located in the ear and they can fit in a penny..our ear never stops working,even while you are sleeping..It continously picks up sound,but the brain simply shut it down..Headphones can increase the count of bacteria around 700 times
