In 10 cats, an ipsilateral section of the inferior alveolar nerve was performed following which horseradish peroxidase was deposited in cavity preparations of either ipsicentral incisors (8) or canines (2). The animals were sacrificed in 24 h, and the ipsilateral nerve to mylohyoid and both semilunar ganglia were prepared histochemically for observation. Labeled axons were found in 6 of 8 cats, whose incisors were prepared, and 4 of the 6 had labeled ganglion cells. In the two remaining cats with incisor preparations, no labeled ganglion cells were found; however, labeled axons were found in the mylohyoid nerve. Neither labeled axons or cells were found in those cats whose canines were prepared. One case of cross-innervation was noted. These results suggest that in addition to the inferior alveolar nerve, the nerve to mylohyoid and possibly other accessory neural pathways are involved in incisor innervation in cats.
在10只猫中，进行了下牙槽神经的同侧切断术，随后将辣根过氧化物酶注入同侧中切牙（8只）或犬齿（2只）的髓腔制备物中。在24小时后处死动物，并对同侧下颌舌骨肌神经和两个半月神经节进行组织化学制备以进行观察。在制备了中切牙的8只猫中的6只中发现了标记轴突，其中6只中的4只具有标记的神经节细胞。在其余两只制备了中切牙的猫中，未发现标记的神经节细胞；然而，在下颌舌骨肌神经中发现了标记轴突。在制备了犬齿的猫中未发现标记的轴突或细胞。记录到1例交叉神经支配情况。这些结果表明，除了下牙槽神经外，下颌舌骨肌神经以及可能的其他辅助神经通路也参与了猫中切牙的神经支配。
