Mechanism of sneezing - Normally, sneezing is an involuntary reflex, which is controlled by a complex interaction of nerve fibres. A variety of receptor sites, situated in the nose, reports about the irritation or foreign substance to the brain for inducing sneezing by releasing histamine, for clearing the nose. Receptors are sensitive to infection, touch, smells of dust, chemical gases, fumes, temperature and exposure to extreme cold air and water (the main offender). Usually, sneeze begins with a deep inspiration and closed glottis, which suddenly opens after gaining pressure from contraction of the diaphragm, abdomen muscles and other muscles which compress the lungs to let out the trapped air with force through nose and mouth. So with an explosive sound, throw of air occurs as a sneeze. Sneezing also involves contraction of the muscles of face, neck and eyes. Sometimes, sneezing air speed is measured more than 120 km/per hour. Normally, people sneeze once or twice during early morning or daytime to clear the nose.\n\nFor more info, go to the source...

I don't think so, and I've never heard this before.  I have heard that your heart stops momentarily when you sneeze though.

Mucus, particulate matter that was floating in the air (dust, pollen, saw dust, etc.) probably macrophages, and white blood cells (which fight bad guys).  Of course some sneezes are wetter than other and might include saliva.  Lastly there is the air that is forcefully expelled.

yes.  you sneeze when something irritates your inner nose.  all that happens is that a little piece of dust gets in the wrong place, and you wake up sneezing--but this does not happen very often.  it is very rare

The most common belief is that your soul leaves the body for a short time, so by saying "bless you! (from "bless your soul") the person would be protected. It is also true that your heart stops when you sneeze. The "bless you" is also supposed to keep the devil from entering your throat when sneezing. In Romanian, for example, we say either "health" or "luck", we don't use the "bless you".

its possible that when you sneeze, your eyes close reflexively, to prevent your eyes from getting contaminated by whatever is coming out of your nose and mouth.  As well, the urge to sneeze (that tingling feeling in your nose) may play a part, due to the optic nerves for your eyes laying close to the nerves for your nose and recieveing some residual signal...

Because the pressure of the sneeze, you close your eyes. You can't control them because its something the body controls. Try holding your nose or biting your tongue though if you're about to sneeze. Then you don't.

A sternutation or, more commonly known, sneeze is a semi-autonomous, convulsive expulsion of air from the nose and mouth. This air can reach speeds of 70 m/s (250 km/h) and an unimpeded sneeze sends two to five thousand bacteria-filled droplets into the air\n\nThis was also interesting:\n\nFebruary 2002 - Your brain musters a host of muscles to clear irritants from your nose at speeds up to 100 mph.\n\nEver try to stop a sneeze? Not easy, is it?\n\nSneezing is a reflex. "When your nose itches you sneeze," just as your knee jerks when a doctor taps it, says California allergist William E. Berger, M.D., a member of the American College of Allergy, Asthma and Immunology. "Closing your eyes when you sneeze is also part of the reflex reaction."\n\nSneezing may seem simple, but it's more involved than you think. Here's how it works: Your nose often warns you a sneeze is coming. An irritant makes your nose start to itch or tickle.\n\nThen the part of your brain termed a "sneeze center" sends a message to designated muscles. "The signal from the brain tells our body to sneeze as a means of clearing out the irritating particles," says Dr. Berger.\n\nThe chest, abdomen, diaphragm, vocal cords, throat and eyelids join in a certain order to launch a sneeze. Presto -- your nose releases the irritant that's causing that itch. A sneeze propels particles from your nose at a speed of up to 100 miles per hour.\n\nSome particles sneak into your nose in a normal breath. A lot more come from colds or allergies. But the cause of your sneeze could also be bright sunshine.\n\nStrange as it sounds, bright light causes one out of three people to sneeze. Some doctors call them "photics," from the Greek meaning "of light." Photic sneezers can blame their parents -- you inherit this trait.\n\nIf your sneeze comes with chest congestion, headache, yellow or green nasal discharge, fever or a stuffy nose, you may want to see a doctor. You could have a cold or allergy.\n\nYou may be tempted to stop a sneeze. Don't.

In the old days it was belived that when a person sneezed then they were expeling a demond from their body.  It was a common proper way to respond to a sneeze, blessing the person who had desposed of the demond.

In the short term you can stop sneezing by pressing hard on the middle of your top lip. That disrupts the nerve impulses from the nose and will kill most sneezing. \n\nIn the long term you need to treat whatever os causing you to sneeze, whther that's an allegy or an infection. Anti-allergy medication often works.

A self-sneezer; I sometimes take a piece of rolled up tissue stick it up in my nose to tickle it and make myself sneeze......'cause it feels good.

Well, I assume you are talking about the defences of the body. The first line of defence is protective structures that form barriers. The main structure is your skin. Also, there are protective reflexes, such as coughing and sneezing.

When sinus around your nose is releasing too much liquid to your nose, and block your air passage, the sneeze mechanism in your brain tells you to sneeze.
