"predeglutitive: aspiration occurs before the swallowing reflex is initiated"
"intradeglutitive: aspiration occurs during the swallowing act"
"postdeglutitive: aspiration occurs after the main bolus has passed the pharynx"
"If material enters the larynx but remains above the vocal folds, this is called penetration 1. Aspiration is used if material passes below the level of the vocal folds, i.e. subglottic. Silent aspiration occurs without a reflexive or conscious effort to expel material 1,2."

"Macro-aspiration can occur during eating or drinking and may occasionally occur in healthy individuals (e.g., simultaneously talking and eating) and should provoke a vigorous cough reflex. Numerous pathologies can cause laryngopharyngeal dysfunction that predisposes to recurrent aspirations:"
"neurological insults (e.g. stroke, palsy of cranial nerves IX, X and XII or neurodegenerative diseases) can result in impaired coordination of deglutition"
"alterations of normal anatomy (e.g. tumour, after operation or radiation) and impaired pharyngooesophageal clearance are predisposing factors"
