作者用辣根过氧化物酶法追踪大鼠二腹肌前腹神经纤维的来源。实验结果表明:大鼠的三叉神经节分为大、小两个节。二腹肌前腹的感觉纤维起源于同侧的小节,本体感觉纤维不是来自三叉神经中脑核,运动神经纤维来自同侧三叉神经运动核尾侧半腹内侧部的背内侧份。 The authors used horseradish peroxidase method to track the origin of the anterior abdominal nerve fibers in the rat’s abdominal muscles. Experimental results show that: the rat’s trigeminal ganglion is divided into large and small two sections. The sensory fibers of the ventral anterior abdominal ventral originate from the ipsilateral segments, the proprioceptive fibers are not from the medial nucleus of the trigeminal nerve, and the motor nerve fibers are from the dorsal medial part of the medial part of the ventral medial part of the ipsilateral trigeminal motor nucleus.
