A dull note (soft, muffled thud) signals abnormal density in the lungs, as with pneumonia, pleural effusion, atelectasis, or tumor. Lungs are hyperinflated with chronic emphysema, which results in hyperresonance where you would expect cardiac dullness. Dullness behind the right breast occurs with right middle lobe pneumonia. Asymmetry is important: one side with prominent dullness or marked hyperresonance indicates underlying disease. Hyperresonance is a lower- pitched, booming sound found when too much air is present such as in emphysema or pneumothorax. A dull note (soft, muffled thud) signals abnormal density in the lungs, as with pneumonia, pleural effusion, atelectasis, or tumor Facial sensation controlled by which CN: Jarvis 283, the trigeminal nerve (CN V) carries the afferent sensation into the brain, and the facial nerve (CN VII) carries the efferent message that stimulates the blink. Note the facial expression and the symmetry of movement, which reflect the functioning of cranial nerve VII. Also, observe for any involuntary movements, edema, or lesions.
