How about cough?
Special sensory proteins called receptors were found on the surface of some of the cells that had the upper respiratory tract. These receptors are located in the back of the throat, the trachea and the upper bronchi, up to the lungs.
When these receptors are stimulated, they send a signal to sensory nerve fibers, such as those found in the vaginal nerve and then transmit the information of sensory fibers to the brain for its interpretation.
The part of the brain that monitors the area of the throat and the upper part of the air is called a "center of cough." When the center of the cough receives a signal that the coating of the respiratory tract is irritating, the muscles of the throat and the chest receive signs of action that stimulate the mechanism of cough.
