Had a bit of sphincter chat last weekend. I was surprised at the sheer number of sphincters we have. I mean you only really think of the big dog.
A sphincter is a circular muscle that normally maintains constriction of a natural body passage or orifice and which relaxes as required by normal physiological functioning. Sphincters are found in many animals. There are over 60 types in the human body, some microscopically small, in particular the millions of precapillary sphincters.[1] Sphincters relax at death, often releasing fluids and fæces.
my gf thought for ages that a sphincter was a word for a ‘lady gooch’ and for a while kept using it massively out of context. After I told her what is actually means she understood why everyone at work had looked at her strangely for the last few months.
Greyfriars Sphincter, the heartwarming story of a microscopically small sphincter which remained clenched within its master’s rectum for many years after his death.
