Facts about Human Nervous System

Facts about Human Nervous System

Below are the sample amazing and interesting facts about the human nervous system:
Neuron development
The  development  of  neuron cells  usually  decrease  with  the  age,  at  the  time  of  fetus  development  in the  womb the  rate is 250000 neurons  per  minute  though  this  decreases  to  almost  zero  in  adult. At birth the  kid  will  have around 10 million nerve  cells.

Number of cells
An adult human will have like 10 billion neuron cell. They  are  unlimited number  in  the  human brain, from the  estimate they  are  said  to  be more  than  the  stars  in the  milky way.
Speed of the nervous  system
Since  the  system  is  used  to help  the  body  to  detect  changes  in  the  surrounding it  has  to  be  very  fast  in the  transmission of  signals. The  impulse  are  propelled at  a  speed  of  100  meters  per  second. The message from the organ to brain is  80 miles  per  hour.

The spinal cord
The human spinal cord consists of about 13,500,000 neurons.
Control  in  contrast
The brain  being  divided  to  two  hemisphere, the  right and  the  left, it  works  in  a  way  that  the right  part  controls  the  left  side  of  the  body  while  the  right  part  controls  the  right side.
Weight of  the  brain
The  weight  varies  with  sex, in males it’s about  1375 g while  in  the  female  counterpart is 1275 g  in the course  of growth 1 g is  lost  yearly.
Active and largest cells
Of all the cells  in the  brain 4% are  active, 965 in resting  phase  as  reserve  cells. Neurons  are  the  largest  cells in human  body , yet  being  cells  they  does  not  cell  division by  mitosis.
