摘　　要：用ＨＲＰ法研究证明，支配山羊胸腺的初级传入神经来源于双侧Ｃ１～Ｔ５ 脊神经节，以同侧为主；其标记神经元的分布呈双峰型；在双侧结状节也出现少量标记细胞，山羊胸腺的感觉经两侧神经传入，以交感途径占优势；交感节后纤维来自双侧颈前节、颈中节、星状节及Ｔ２～Ｔ５ 椎旁节，其中颈中节和星状节的标记细胞最多；在双侧Ｃ１～２节脊髓腹角和延髓疑核出现标记细胞较多，延髓迷走神经背核、面后核和脊上核出现较少的标记细胞。HRP was injected into the thymus gland monolateral of goat.The results were as follows:The primary afferente nerves of the thymus gland of goat originated from bilateral C 1-T 5 dorsal root ganglion,maily in homolateral.The number of the labelled neurons changed with two peaks.A few of labelled cells also appeared in nodesum ganglion bilaterally.This indicated that the sensory nerves of the thymus gland of goat afferented from bilateral,with the sympathetic way being dominant.The sympathetic caudalis ganglion fibers originated from cranial cervical ganglion,cervical medium ganglion,stellatum ganglion and T 2-T 5 paraveterbral ganglion.The majority of labelled neurons was located in the cervical medium ganglion and stellatum ganglion.The majority labelled neurons were found in the anterior horn of the first and second cervical spinal cord and the nuclei ambiguus,and small number neurons appeared in the nuclei vetroambiguus and the nuclei supraspinalis.
