Sensory receptors are also utilised when body parts are involved. These receptors include nociceptors, which respond to chemical stimuli like bodily hormones, slowly adapting receptors that respond to mechanical stimuli, and fast adapting receptors that respond to mechanical stimuli.
Afferent impulses are sent to the brain's medulla to begin the reflex, which is subsequently used to evaluate the stimuli. The signal then passes through the larynx and bronchial tree after being triggered by the medulla's efferent impulses. The intercostal muscles, abdominal wall, diaphragm, and pelvic floor are then involved in a series of events that culminate in the reflex action of coughing.
