关于颈部交感神经节的形态学及其灰交通支与颈脊神经相联系的情况,在许多解剖学教科书的记载中大致相同。其要点一般可归纳为:(1)颈部正常拥有上、中、下三个交感神经节;(2)颈上神经节最大,发出的灰交通支与上位三或四根颈脊神经的前支相连;(3)颈中神经节最小,由之发出至第五及第六颈脊神经前支的灰交通支,有时也可达第四及第七颈脊神经前支;(4)锁骨下襻出自颈中神经节,绕过锁骨下动脉与颈下神经节相连;(5)颈下神经节每与第一胸交感神经节愈合构成星状神经节,发出灰交通支至下位二或三根颈脊神经的前支。但在若干教本中也指出上述情况可以发生变化:如颈上神经节可在一 Morphology of the cervical sympathetic ganglia and the relationship between the gray traffic branch and the cervical spinal nerves are generally the same in many anatomical textbooks. The general points can be summarized as follows: (1) The neck normally has three sympathetic upper, middle and lower sympathetic ganglia; (2) The upper cervical ganglion has the largest branch of gray traffic and the upper three or four cervical spinal nerves Connected; (3) the smallest cervical ganglion, which issued to the fifth and sixth cervical anterior branch of the gray traffic branch, sometimes up to the fourth and seventh cervical anterior branch of the nerves; (4) (5) the inferior cervical ganglion and the first sympathetic ganglia sympathetic ganglia constitute the stellate ganglion, send gray traffic to the next two or three cervical spinal nerves Former branch. However, in a number of textbooks also pointed out that the above situation can change: If the superior cervical ganglion in a
