The Human Body
I do not know if this information has been posted previously. If so, my apologies, if not, enjoy:
The average human body contains enough:
iron to make a 3 inch nail;
sulfur to kill all fleas on an average dog;
carbon to make 900 pencils;
potassium to fire a toy cannon;
fat to make 7 bars of soap;
phosphorous to make 2,200 match heads;
and water to fill a ten-gallon tank.
The human brains consists of more than 100 billion neurons(nerve cells) through which the brain's commands are sentin the form of electric pulses. These pulses travel at morethan 250 mph, creating enough electricity to power a lightbulb. The brain consumes more energy than any other organ.
Humans actually do not see with our eyes - we see with our brains. The eyes basically are the cameras of the brain. One-quarter of the brain is used to control the eyes.
The human head contains 22 bones, consisting of the cranium and the facial bones. The cranium is formed by 8 bones: the frontal bone, two parietal bones, two temporal bones, the occipital bone in the back, the ethmoid bone behind the nose, and the sphenoid bone. The face consists of 14 bones including the maxilla (upper jaw) and mandible (lower jaw).
