对大鼠颈胸交感神经进行了解剖学研究。详细描述了白色和灰色交通支以及上级颈神经节、颈中神经节和星状神经节的分布。用辣根过氧化物酶（HRP）逆行标记背根和交感神经节神经元，观察其数量、节段分布和定位。将HRP应用于供应骨骼肌的前肢神经（桡神经深支，RP）或有毛皮肤（N。腋神经上级臂外侧皮神经，CB）、混合神经（正中神经，ME;尺神经，UL;桡神经，RA）和供应背部多毛皮肤的胸段神经（背侧皮神经，CD）以及混合肋间内神经（IC）。所有感觉神经元和交感神经元均位于同侧。在前肢神经中，感觉体通常局限于两个或三个相邻的背根神经节（CB通常为C6-7; ME通常为C7-8; RA和RP通常为C7-Th 1; UL通常为C8-Th 1）。几乎所有的交感神经细胞都位于颈中神经节和星状神经节（C6-Th 3融合）。Th 4和Th 5细胞占0 ~ 0.4%，上级颈神经节无细胞。在躯干神经感觉胞体严格节段组织。交感神经胞体在4-5个节段中分布较广，节段神经节占50-55%，尾段占41%。从这些数据估计，400个（28%）和1050个传入神经元投射到CB，1660个（29%）和4050个投射到RA，540个（42%）和760个投射到RP，1010个（22%）和3670个投射到ME，880个（22%）和3040个投射到UL，350例（25%）和1040例进入IC，500例（27%）和1370例进入CD。
The anatomy of the cervicothoracic sympathetic nerves was studied in the rat. Details of the arrangements of white and grey rami communicantes and superior cervical, middle cervical and stellate ganglia are given. Dorsal root and sympathetic ganglion neurones projecting to skin and muscle of the forelimb and trunk were labelled retrogradely with horseradish peroxidase (HRP) in order to study their number, segmental distribution and location. HRP was applied to forelimb nerves supplying skeletal muscles (Ramus profundus of radial nerve, RP) or hairy skin (N. cutaneus brachii lateralis superior of axillary nerve, CB), to mixed nerves (median nerve, ME; ulnar nerve, UL; radial nerve, RA) and to segmental thoracic nerves supplying hairy skin of the back (dorsal cutaneous nerve, CD) and to mixed internal intercostal nerves (IC). All sensory and sympathetic neurones were located ipsilaterally. In the forelimb nerves sensory somata were commonly restricted to two or three adjacent dorsal root ganglia (usually C6-7 for CB; C7-8 for ME; C7-Th1 for RA and RP; C8-Th1 for UL). Nearly all of the sympathetic somata were located in the middle cervical and stellate ganglia (fusion of C6-Th3). Some 0-0.4% lay in Th4 and Th5, none in the superior cervical ganglia. In the trunk nerves sensory somata were strictly segmentally organized. Sympathetic somata were distributed more widely over 4-5 segments with 50-55% in the segmental ganglion and up to 41% in the next caudal segment. From the data, it is estimated that 400 sympathetic (28%) and 1050 afferent neurones project into CB, 1660 (29%) and 4050 into RA, 540 (42%) and 760 into RP, 1010 (22%) and 3670 into ME, 880 (22%) and 3040 into UL, 350 (25%) and 1040 into IC and 500 (27%) and 1370 into CD.
