支配家兔下颌淋巴结的神经来源

本实验用ＨＲＰ逆行追踪法对家兔下颌淋巴结的神经来源进行了研究。结果表明；在同侧三叉神经半月状神经节和Ｃ１－４脊神经出现标记神经原，以三叉神经经半月状神经的标记细胞最多，提示下颌淋巴结的初级感觉主要经三叉神经传入；在同侧的颈前节，星状神经节及Ｔ２－３椎旁节出现标记的交感后神经原，主要出现于颈前节的吻侧端。

The Nerve Origination of Mandibular Lymphonode of Rabbit

The present paper studied the nerve origination of mandibular iymphonode of rabbit with HRP method. The results were as follows:The labbled primary sensory neurons distributed on trigeminal ganglion and C1 4 dorsal root ganglion and concentrated on trigeminal ganglion in injecting side. The sympathetic ganglionic neurons lay in cranial cervical ganglion cervical medium ganglion ,stellate gangloin and T2 3 paraventebral ganglion and concentrated on cranial cervical ganglion. The results not only added morphological information for the innervation of immune organs,but also provided morphological evidence for mechanism of acupuncture action to the nerve regulation of immune organ.
