>From a physiological standpoint, the diaphragm is not considered to
be involuntary - but based on the description you give there, I
understand your use of the term in this context (what you are calling
"involuntary", I would call "relaxation" - physiologically they are
distinct terms). Relaxation _can_ be controlled (and is - probably-
in the diaphragm - (for physiologists - I'm referring to the
post-inspiratory discharge of the phrenic nerve here.))
