These are most marked around a ver- tical axis, giving rise to an inward and outward movement of rota- tion, but there are also movements of less extent in all directions. It is in fact through the movements of these cartilages to which the vocal bands are attached posteri- orly, that most of the important changes in the tension, approxi- mation, etc., of the latter are pro- duced. The lungs are to be regarded as the bellows furnishing the neces- sary wind-power to set the vocal bands vibrating, while the larynx has respiratory as well as vocal functions, as has been already learned. Assuming that the stu- dent has a good knowledge of the 41.
