What is another reflex and reflex arc other then pupillary, blinking and knee-jerking?
Another example of a reflex and reflex arc is the gag reflex. The gag reflex is a protective mechanism that helps prevent foreign objects from entering the airway and causing choking. When a person's soft palate, uvula, back of the tongue, or back of the throat is stimulated, it triggers the gag reflex, causing the person to gag or cough.
The reflex arc for the gag reflex involves sensory receptors in the back of the throat sending signals to the brainstem. The brainstem then coordinates a response that causes the contraction of muscles in the throat and pharynx, leading to the gagging reflex. This reflex arc bypasses higher brain centers and allows for a quick and automatic response to potentially harmful stimuli in the throat.
