主要和次要肌纺锤体传入通常是根据传导速度（CV）来区分的。后肢研究的可靠性得到了CV和动态灵敏度之间的相关性（Matthews, 1972）以及它们的中心终止（Mendell & Henneman, 1971; Kirkwood & Sears, 1974; Stauffer, Watt, Taylor, Reinking & Stuart, 1976; Brown & Fyffe, 1978）的支持。然而，由于传导距离短且难以测量，在下颌肌肉传入神经的分类中使用CV被证明是不令人满意的。此外，传入纤维直径并没有被发现是双峰分布的（Morimoto, Inoue & Kawamura, 1982）。这表明，必须使用其他方法来区分这些肌肉中的初级和次级纺锤体传入。在本研究中，我们将下颌提肌纺锤体传入的被动反应与其中心投射的形态联系起来。
Primary and secondary muscle spindle afferents are usually separated on the basis of conduction velocity (CV). The reliability of this in hindlimb studies is supported by the correlations between CV and dynamic sensitivity (Matthews, 1972) as well as by their central terminations (Mendell & Henneman, 1971; Kirkwood & Sears, 1974; Stauffer, Watt, Taylor, Reinking & Stuart, 1976; Brown & Fyffe, 1978). However, the use of CV in the classification of jaw muscle afferents has proved unsatisfactory since conduction distances are short and difficult to measure. Also, afferent fibre diameters have not been found to be bimodally distributed (Morimoto, Inoue & Kawamura, 1982). This suggests that other ways of distinguishing between primary and secondary spindle afferents in these muscles must be used. In the present study we correlate passive responses of jaw-elevator muscle spindle afferents with the morphology of their central projections.
