From American Heritage Online Dictionary:

Sphincter:

>>A ringlike muscle that normally maintains constriction of a body passage or orifice and that relaxes as required by normal physiological functioning.<<

Basically, it's a round muscle that closes off an opening or hollow passage, within or on the outside of the body.  When no longer required, it relaxes and allows for full function of said opening or passage.

The two most-known sphincters are the anal (which is the countermeasure one, and the one you employ to hold back a BM or urine) and the vaginal.  There are others, though, including ones involving the heart, esophagus, and stomach.

And it's spelled sphincter... Smiley

I've often wondered about this one too.  So when you employ this countermeasure, you're supposed to act as if you're holding in a fart, or trying to expel a fart??

my impression is that you squeeze as if you're "pinching the loaf off"

Retcopper-

What do you mean talk like Cesium.  I tried to make it simple, alterego1 didn't seem to understand it.  Sorry if my explanation was too realistic for you.

The muscular action you would want to employ would be the one used to hold back a fart Smiley  Happy, retcopper?

Going the other way, like you were trying to pass gas, might accomplish something similar, but it also involves constricting the diaphragm and making your breathing unnatural, producing an unacceptably weird tracing on that channel, and probably on the thoracic as well...
