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

The neurons associated with the left first sacral sympathetic trunk ganglion (STG S1), an autonomic ganglion particularly concerned in the innervation of the smooth and striated musculature associated with pelvic organs, were identified in the pig, using the non-trans-synaptic fluorescent retrograde neuronal tracer Fast Blue. The labelled neurons were located mostly ipsilaterally, in the intermediolateral nucleus of the spinal cord segments T10-L5, in the sympathetic trunk ganglia L3-Co1, in the caudal mesenteric ganglia, in the pelvic ganglia, and in the spinal ganglia T13-S4. Our results could indicate the existence of visceral neuronal circuits concerning the ganglia of the sympathetic trunk and the caudal mesenteric, pelvic and spinal ganglia with or without the intervention of the central nervous system, whose identification and preservation during surgical treatments could be helpful in reducing the risk of subsequent urinary and sexual disfunctions. 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

A study of the origin of the sympathetic postganglionic axons innervating the trachealis muscle of the dog was carried out using horseradish peroxidase as a retrograde neuronal marker. It was demonstrated that this technique is not fruitful in adult dogs, but in 12 puppies demonstrated that these neurons arise from the cervicothoracic, middle cervical and cranial cervical ganglia. Contributions of nucleus ambiguus, nucleus of the vagus nerve and the distal ganglion of the vagus nerve to innervation of the trachealis muscle were also demonstrated. 相似文献

The neurons in bilateral superior cervical ganglia (SCG) innervating the chick pineal gland were labelled by using the technique of retrograde axonal labelling with cholera toxin B subunit linked to horseradish peroxidase (CTB-HRP). To our results, perikarya of these sympathetic neurons distributed from rostral to caudal in the SCG, and mainly localized in the opposite side of the paravertebral trunk. The fibres of these neurons were collected by the cephalic carotid nerve. According to the sizes of somal area and dendritic field, these sympathetic neurons projecting to the pineal gland were classified into four major groups: group I cells (52.4%) with a small somal area (303.5 μm2 on average) and narrow dendritic field (3767.8 μm2 on average), group II cells (39.0%) with a middle-sized somal area (473.3 μm2 ) and middle-sized dendritic field (7522.2 μm2 ), group III cells (6.4%) with a middle-sized somal area (473.4 μm2 ) and wide dendritic field (13 104.4 μm2 ), and group IV cells (2.2%) with a large somal area (940.7 μm2 ) and wide dendritic field (14 553.2 μm2 ). Of these pineal projecting neurons, most took on a lesser dendritic field. The neurons with small or middle-sized dendritic field from group I and II were about 91.4% of the total neurons labelled with CTB-HRP, and the neurons with wide dendritic field from group III and IV were less with 8.6%. 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
