About 50% of the human vocal muscle fibres possess several endplates. The direct relation between the number of endplates and rate of contraction, which has been postulated in animals, does not apply to the human vocal muscle. However, it may be that this relation is not indispensable to the particular function this muscle is required to perform and undoubtedly justifies a possible pattern of selective muscle contraction, or better still, of a contraction regulated by a particular, independent mechanism. This mechanism is postulated and discussed.
