摘 要：正 The vocal organ of birds, the syrinx, is formed by modified cartilages of the trachea and/or bronchi and a number of muscles. The syrinx is relatively inaccessible. Although its anatomy, innervation, muscular control, and driving air flow are well described in some species, the biomechanics of phonation are still poorly understood. Recently, the use of very thin, flexible endoscopes has supported prior speculations on syringeal muscle mechanics, since abduction, adduction, rotation, and tensing of syringeal structures in response to
