检查有髓传入纤维的反射功能。最大的纤维与运动神经元形成直接连接。通过这些直接连接介导的反射放电仅限于肌肉或肌肉的头部，其大的传入纤维受到刺激。由于这个原因，它的结论是，直接反射连接保留的调解拉伸反射，具有相同的分布。中、小型有髓传入纤维通过髓间神经元与运动神经元相连。通过这些多神经元弧路径介导的放电指向屈肌并代表屈肌反射。用于屈肌反射的最小路径是3个神经元之一。与此相反，屈肌腱反射活动像伸肌反射活动一样通过2个神经元的弧进行。通过伸肌双神经元弧的反射活动被抑制，通过屈肌双神经元弧的反射活动在屈肌反射本身的多神经元弧放电的传递过程中被促进。
The reflex function of myelinated afferent fibers is examined. The largest fibers form direct connections with motoneurons. The reflex discharge mediated through these direct connections is restricted to the muscle or head of a muscle, the large afferent fibers of which are stimulated. For this reason it is concluded that the direct reflex connections are reserved for the mediation of stretch reflexes, which have identical distribution. The medium and small myelinated afferent fibers are connected to motoneurons through internuncial neurons. The discharges mediated through these multineuron-arc paths are directed to flexor muscles and represent the flexor reflex. The minimum path devoted to the flexor reflex is one of 3 neurons. In contrast the flexor tendon-jerk activity like the extensor tendon-jerk activity is conducted through arcs of 2 neurons. Reflex activity through extensor two-neuron-arcs is inhibited, that through flexor 2-neuron-arcs is facilitated during the transmission of the multineuron-arc discharges of the flexor reflex proper.
