将CB－HRP溶液注入鸡输卵管子宫部浆膜下，取泄殖腔神经节和双侧阻部内神经以及肠神经直肠段，制成50μm厚度的边疆冰冻切片，TMB反应，明视野观察。结果发现：鸡输卵管子宫部受泄殖腔神经节和双侧阻部内神经节的副交感节后神经元支配；双侧阴部内神经节的标记细胞无显著差异；说明尽管母鸡输卵管子宫部是单侧发育器官，但其受双侧阴部内神经的融交感节后神经元的支配。鸡输卵管子宫部还受肠神经的节后神经元的支配。另外本实验对汇殖腔神经节、阴部内神经及肠神经直肠段进行了大体解剖观察。 相似文献

Sympathetic, parasympathetic and sensory neurons were labeled by injections of horseradish peroxidase into various regions of the heart in 33 Beijing ducks. Sympathetic postganglionic neurons innervating the heart were located in the paravertebral ganglia C15 (C16 is the last cervical segment in the duck) to T3, especially in the ganglion T1. The coronary sulcus and ventricle were more abundantly innervated by sympathetic neurons than the atrium. The left side of the heart was preferentially innervated by sympathetic postganglionic neurons in the left side of paravertebral ganglia but the right side of the heart were equally supplied from the right and left ganglia. Within the medulla oblongata, the number of labeled vagal preganglionic neurons in the nucleus ambiguus was much greater than that in the dorsal motor nucleus of the vagus nerve. Labeled neurons of the nucleus ambiguus were found in many ducks injected into the coronary sulcus. Cardiac sensory neurons were observed in the dorsal root ganglia C15 to T2 (highest in the ganglion T1) and in the nodose and jugular ganglia of the vagus nerve. These labeled neurons probably form the afferent and efferent limbs of cardiac reflexes and control circulation in the Beijing duck. 相似文献

Sympathetic postganglionic and sensory neurons were labelled by injections of horseradish peroxidase into the testis of the male chicken. The total number of labelled neurons in the paravertebral, prevertebral, dorsal root and nodose ganglia was 943 on average for five chickens. Sympathetic postganglionic neurons were located in the paravertebral ganglia T3-LS3 (10% of the total number of labelled neurons), especially in T6 and T7, and in the prevertebral ganglia adjacent to the adrenal glands and aorta (19%). They were found almost ipsilaterally. No labelled neurons were observed in the dorsal motor nucleus of the vagus. Sensory neurons were found bilaterally in the dorsal root ganglia T2-LS3 (71%), especially in T5 to T7. Over a quarter of labelled sensory neurons were located in the contralateral dorsal root ganglia. In the nodose ganglia, only a few labelled sensory neurons were observed (much less than 1%). These results indicate that, unlike the ovary, the testis of the chicken tends to be innervated by ipsilaterally located sympathetic postganglionic and sensory neurons, with the sensory neurons being more numerous than the sympathetic postganglionic neurons. 相似文献

应用CB-HRP溶液注入母鸡输卵管子宫部浆膜下，四甲基联苯胺（TMB）组织化学呈色，以探察母鸡输卵管子宫部初级感觉神经元的定位。结果表明：母鸡输卵管子宫部的初级感觉神经元位于双侧T1-LS13脊神经节、颈静脉神经节和结状神经节。标记细胞数分布不均，在体左侧多于体右侧，在脊神经节多于颈静脉神经节和结状神经节。在脊神经节内标记细胞有T5-LS1和LS8-LS11前后两个相对集中区，峰值分别在T7和LS11。说明尽管母鸡输卵管子宫部是单侧发育成熟脏器，但其感觉沿双侧脊神经和迷走神经传人中枢，以体左侧传入为主；且感觉经脊神经传入较迷走神经传入中枢优势明显。 相似文献

艇ＨＲＰ法对兔减压神经进行了研究，标记的传入神经元绝大多数位于迷走神经结状节尾侧半部偏一侧，少数见于颈静脉神经节，其中枢突标记终末见于延髓闩以上的孤束核内侧部，腹侧部以及迷背核内。在颈前节也出现标记细胞，表明减压神经中也含有起源于 前节的交感节后纤维成分。主动脉压力感受器有经减压神经来的感觉神经交感节后神经纤维支配。提示减压神经是含有一般内脏传入和一般内脏传出纤维的混合神经，为研究心血管生理提供了 相似文献

The purpose of this investigation was to determine the central distribution of the efferent neurons of the recurrent laryngeal nerve (RLN) in the sheep by the use of the retrograde transport of the fluorescent tracer Fast Blue. The distribution of the RLN neurons was also compared with that of the neurons simultaneously labelled by injection of another tracer, Diamidino Yellow dihydrochloride, into the cervical trunk of the vagus nerve (CTV). Injections of the tracer into the CTV resulted in heavy retrograde labelling of neurons in the ipsilateral dorsal motor nucleus of the vagus nerve, in the nucleus ambiguus, in the nucleus retroambigualis and in the reticular formation surrounding the nucleus ambiguus. Following injections of the tracer into the RLN, labelling of neurons was seen over a wide area of the ipsilateral nucleus ambiguus and in the nucleus retroambigualis. Species differences in the distribution of the efferent component of the RLN are discussed, in particular ruminants compared to nonruminants. 相似文献

The distribution of sympathetic and sensory neurones innervating the submandibular gland (SMG) in sheep was studied using retrograde tracing technique. The retrograde tracer Fast Blue (FB) was unilaterally injected into the SMG in five juvenile male sheep under general anaesthesia. After a 4-week survival period, all the animals were reanaesthetized, perfused transcardially with 4% buffered paraformaldehyde and ganglia, which could be considered as a potential sources of sympathetic, and afferent innervation of the gland were bilaterally collected. The FB-labelled sympathetic neurones were found in the ipsilateral superior and middle cervical ganglion. Many labelled neurones were distributed in the ipsilateral jugular and nodose ganglia of the vagus nerve and smaller numbers of the nerve cells were also found in ipsilateral C1-C3 dorsal root ganglia (DRG). No labelled neurones were observed in the ipsilateral stellate ganglion, trigeminal ganglion, C4-C8 DRG and in all contralateral ganglia. The present study revealed that the majority of sympathetic neurones projecting to the sheep SMG are found in the superior cervical ganglion but some of them are also distributed in the middle cervical ganglion. Most of the afferent neurones are located in the jugular and nodose ganglia of vagus nerve but C1-C3 DRG also comprise some of these nerve cells. 相似文献

The distribution of neurons projecting to the mammary gland was investigated by using the retrograde tracing method in juvenile pigs (n = 12). Fluorescent retrograde tracer Fast Blue (FB) was injected into the nipple (n = 3) or parenchyma (n = 3) of the second, right thoracic mamma or into the nipple (n = 3) and parenchyma (n = 3) of the last, right abdominal mamma. FB-positive (FB+) mammary gland-projecting neurons were found in some right dorsal root ganglia (DRG) and sympathetic chain ganglia (SChG) only. After injection of the tracer into the second, right thoracic mamma, FB+ neurons were observed in Th9-Th12 DRG but most of them were located in Th11 and Th12 ganglia. As concerns SChG, FB+ neurons were found in Th1-Th4, Th7-Th14 and L1-L4 ganglia. The vast majority of them were located in Th10 and Th11 SChG, which appeared to be the main sources of efferent innervation of this mamma. Neurons projecting to the last right abdominal mamma were found in L1-L3 DRG and L1-L4 SChG but most of them were located in L1-L2 ganglia and L1-L2 ganglia, respectively. This study for the first time has disclosed the localization of neurons supplying the mammary gland in larger domestic animal species, the pig, by using the retrograde tracing method. 相似文献
