A contraction of the diaphragm that repeats several times per minute. In humans, the abrupt rush of air into the lungs causes the epiglottis to close, creating a hic sound. Also known as synchronous diaphragmatic flutter (SDF), or singultus, from the Latin singult, the act of catching one's breath while sobbing. The hiccup is an involuntary action involving a reflex arc. [from HPO]
