2. The theological explanation tries to
see beneficial purpose in a given
phenomenon.
This jerky inspiratory effort associated
with closure of glottis, is opposite of
jerky expiratory effort such as sneeze
or cough, which are aimed at
throwing out foreign material from
the lungs.
The hiccups therefore appear to be
efforts to jerkily bring in outside air,
apparently to prevent possible
collapse, as a result of the signal for
the hiccup, which appears to be
anything that mimics the sudden
collapse.
So it appears that, any stimulation of
vagus or phrenic nerves or diaphragm
3. itself; due to any pathology, when
appears akin to beginning of the
process of sudden collapse, the
hiccups are generated.
Experimental verification may be
done by simulating impending
collapse of various degrees and
studying qualitative and quantitative
the response of body.
