One such reflex is a cough. This is typically triggered when the larynx senses that something has penetrated this upper portion of the airway. The cough, then, acts as a protective mechanism, serving to cough out or expel something at risk for being inhaled. There are normal reflexive thresholds or âtriggersâ that exist in the larynx. When these thresholds are lowered (i.e., more sensitive), less stimulation is required to trigger a cough.
A reflexive verb is a verb that has an object which is the same as the subject of the verb ==> the action of the reflexive verb is something one is doing to or for oneself. Some verbs are always reflexive, others are not. This is discussed in more detail below. Click here for some examples.
