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).

The human brains consists of more than 100 billion neurons
(nerve cells) through which the brain's commands are sent
in the form of electric pulses. These pulses travel at more
than 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.
