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 reflex is basically an automatic response, something you don't control e.g. your eyes blinking or you hands move away from a hot object. Mainly reflexes are there to prevent â¦ injuries because it's much faster than a voluntary response (actions/response you control).se of the straw is not response to stimulus, and therefore not a reflex. Reflexes follow a Reflex ARC. The Arc is through the spinal cord. While the information gets sent to the brain (you know you touched something hot, or you are choking and coughing), the reflex totally by-passes the brain.
