What is Arnold's reflex associated with?

Arnold's reflex, also known as Arnold's reflex arc, is specifically associated with a reflexive cough that occurs during a deep ear impression. This phenomenon is documented in individuals who have certain anatomical connections between the ear canal and the throat, particularly in the case of certain types of nerve pathways. When the ear canal is stimulated, it can inadvertently trigger a cough reflex due to these connections.

The reflex is linked to the stimulation of the auricular branch of the vagus nerve, which can transmit sensations from the ear area to the brain and affect structures in the throat. This is why a deep ear impression can provoke a coughing response in some individuals. Understanding this reflex is important for hearing instrument specialists as it relates to how ear impressions are taken and how certain stimuli can elicit responses in patients.

The other responses refer to reflex actions associated with different stimuli, such as swallowing, allergens, or light, which do not pertain to Arnold's reflex and are thus not relevant in this context.
