• Vomiting — The act of vomiting (throwing up) and its result, used as an archaic or regional phonetic variant for the verbal noun 'borâre'; the physiological process of violently and involuntarily expelling gastric contents through the oral cavity; (figurative, pejorative) the act of spewing insults, vulgarities, or heavy words in an uncontrolled manner.
• Antiperistalsis — A physiological or pathological phenomenon consisting of the reversal of the muscular contraction waves of the digestive tract, propagating in the opposite direction of the normal one, from the lower to the upper stages. This structural mechanism can occur as a defense reaction of the body in case of toxic substance ingestion, generating vomiting, or as a severe symptom within mechanical intestinal obstructions and occlusions.
• Autoemesis — A specialized clinical term designating the voluntary, reflexive, or spontaneous induction of vomiting (emesis) by an individual, without the intervention of external emetic factors or chemical medicinal substances; a symptom or behavior often encountered in digestive dynamics disorders or psychiatric neuro-behavioral conditions.
