| 摘 要： | 用~3H-HRP自显影术研究了大鼠上、下颌第一磨牙感觉神经元在三叉神经节内的解剖学定位。结果表明,这些神经元在三叉神经节内按其所支配的牙齿不同虽有一定分布范围,但也存在明显交错与重迭现象。这一研究结果为牙源性牵涉痛发生的机理,提供了解剖学依据。

| Abstract: | The primary sensory neurons innervating the upper and lower first molars of the rat were studiedby ~3H-HRP autoradiography with respect to their localization in the trigeminal ganglion. The results showed labelled neurons were found only in the ganglion ipsilateral to the injection;the labelled neurons innervating upper and lower first molars might be divided into somatotopic areas,however, they intermingled and overlapped in the ganglion. The present findings would seem to be of value for studing the mechanisms of odontogeniousreferred pain. |
