投射纤维

The ventrolateral group of Onuf's nucleus is mainly composed of pudendal motor neurons innervating the external urethral sphincter muscle.

D 区是紧邻 Barrington's 核腹侧的一团神经元，它发出纤维投射至腰骶髓 Ounf 核的背外侧群，而 Ounf 核的背外侧群主要是由支配尿道外括约肌的阴部神经运动神经元组成。

Transported by axoplasmic flow into somata, NGF plays an important role in the development, preservation and survival of cholinergic neuron in BF.

药物损伤BF的胆碱能神经元，或切断穹窿海马伞使隔-海马的纤维投射破坏可导致海马θ节律消失和记忆能力减退。

The precise termination areas of the descending projection from the medullary subnucleus reticularis dorsalis to spinal gray matter in the rat were investigated by injection of an anterograde tracer, phaseol us vulgaris leucoagglu tinin into the SRD.

本研究应用PHA－L顺行追踪技术研究了大风延髓网状背测亚核至脊髓灰质下行投射的终止部位。结果表明：SRD发出的下行纤维走行于脊髓的背外侧京中，从高位至低位，脊髓灰质中的PHA－L顺标终末的密度逐渐降低。

The central complex isprominent. The beetle showed notable 5-HT-like immunoreactivity throughout the wholebrain, which was also strongly labelled by TPH antibody, with the pattern matching that of5-HT. 5-HT-like positive fibers were resolved in all areas of the brain, among which thelamina and suboesophageal ganglion showed the most remarkable dark brownimmunostaining. While, all major neuropil regions, in general, showed low level backgroundafter TPH immunostaining for TPH mainly existing in cytoplasm. The number of 5-HT-likeimmunoreactive neurons was relatively small but possessed extensive varicose arborizations.

免疫组化结果显示，异色瓢虫脑系统呈强5-HT免疫反应，表现为稳定的反应模式；其脑系统对鼠抗TPH单克隆抗体同样呈显著的免疫阳性反应，且反应模式与5-HT一致。5-HT能神经元多为切向神经元，数目相对较少，呈两侧对称分布，主要位于视叶与侧前脑之间、前脑背方及咽下神经节处，其阳性纤维呈明显的静脉曲张状，投射区域较广泛。

Our observation indicates that capsaicin as a nociceptive chemical irritant can selectively activate primary afferent C-fibers to release SP and Glu from their central terminals in the superficial dorsal horn. It seems that the release of SP and Glu acting on NK-1 and NMDA receptors results secondarily in the activation of dorsal horn neurons, transmitting nociceptive information to supraspinal structures.

以上结果表明辣椒素作为一种伤害性的刺激源，可选择性兴奋C类传入纤维，引起其分布于脊髓背角浅层内的末梢大量释放SP和Glu，通过相应受体兴奋背角伤害性感受神经元，包括上行脊-丘束投射神经元，将痛觉信息传递至脑。

These results showed that IM is the most important medullary motor nuclei innervating the vccal organ, the origins of NⅫL (lingual n. of Ⅻ) and NⅫts (tracheosyringeal n. of Ⅻ)in IM were overlapping. And nⅨ-Ⅹ miglt play some...

结果表明，IM是支配鸽发声的重要运动核团，舌下神经的舌分支和气管鸣管分支在IM的投射大部分是交迭的，舌下神经中存在迷走神经的纤维成分，nⅨ—Ⅹ在鸽的摄食反馈和发声中可能具有一定的作用。

Hypocretin neuronpeptide in hypothalamic nuclei and its receptor are involved in the regulation of the Hb on sleep-wakeness process.The Hb is innerved by the lateral hypothalamic area,the lateral preoptic area and the arcuate nucleus.

下丘脑Hypocretin神经肽及其受体参与Hb对睡眠-觉醒调节的作用，且Hb接受下丘脑内睡眠相关结构LHA、LPO、ARC的纤维投射。

But the mechanism is not clear. Morphological studies have showed that medial vestibular nucleus receive the projection of serotoninergic fiber coming from nucleus raphes magus, nucleus raphes obscurus, nucleus raphes pallidus, nucleus raphes dorsalis and express the 5-HT1A, 5-HT 1B, 5-HT 2A, 5-HT 2C receptor.

形态学研究报道MVe可接受来自中缝大核、中缝苍白核、中缝隐核和中缝背核等浓密的5-HT能纤维投射，且MVe神经元表达5-HT1A、5-HT1B、5-HT2A和5-HT2C等受体阳性。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
