A. When the inside of your nose gets a tickle, a message is sent to a special part of your brain called the "sneeze center."
The sneeze center then sends a message to all the muscles that have to work together to create the amazingly complicated process that we call the sneeze. Some of the muscles involved are the abdominal (belly) muscles, the chest muscles, the diaphragm (the large muscle beneath your lungs that makes you breathe), the muscles that control your vocal cords, and muscles in the back of your throat. Don't forget the eyelid muscles!
Did you know that you always close your eyes when you sneeze? It is the job of the sneeze center to make all these muscles work together, in just the right order, to send that irritation flying out of your nose. And fly it does - sneezing can send tiny particles speeding out of your nose at up to 100 miles per hour!

Q. Why is it so inactive around here, these days?
