Abstract

This study centred on the effects of hetero-reinnervation within the rat tongue. Lingual, greater auricular and vagus nerves were used. Proximal segments of each of these nerves were joined to the distal hypoglossal stump using 10/0 nylon suture. Histological sections of the tongue were examined. In lingual hypoglossal cross-union, histological evidence indicated that neuromuscular junction (nmj) reinnervation was present to some degree in all intrinsic tongue muscles and within geniohyoid. Lingual nerve fibres were also found within the dorsal keratinised lingual epithelium, reinnervating taste buds and intralingual ganglia. Greater auricular nerve fibres were unable to make contact with nmjs, nor were they found to any appreciable degree within the lingual mucosa. Vagal nerve fibres were found close to, but not innervating, nmjs, but did reinnervate taste buds, lingual vasculature and intralingual ganglia. It was concluded that nodose cells are unable to reinnervate vacated nmjs, but like lingual fibres can reinnervate lingual mucosa, intralingual ganglia and vasculature.

摘要

本研究聚焦于大鼠舌内异种神经再支配的影响。使用了舌神经、耳大神经和迷走神经。这些神经的近端部分用10/0尼龙缝线与舌下神经远端残端相连。对舌的组织学切片进行了检查。在舌-舌下神经交叉联合中,组织学证据表明,在所有舌内肌和颏舌骨肌内,神经肌肉接头(nmj)再支配在一定程度上存在。在背侧角化舌上皮内也发现了舌神经纤维,它们重新支配味蕾和舌内神经节。耳大神经纤维无法与神经肌肉接头接触,在舌黏膜内也未发现明显程度的耳大神经纤维。迷走神经纤维靠近神经肌肉接头,但未对其进行支配,但确实重新支配了味蕾、舌血管和舌内神经节。得出的结论是,结状细胞无法重新支配空出的神经肌肉接头,但与舌纤维一样,可以重新支配舌黏膜、舌内神经节和血管。
