鹅颈动脉颈神经的解剖学观察和溃变法研究

OBSERVATION AND DEGENERATING STUDY ON THE SUBCAROTID NERVE IN GEESE

鹅颈动脉颈神经分布到颈动脉上的神经丛有两种情况：有神经节与无神经节。溃变结果表明在颈前神经节和颈交感干神经节上都出现有溃变细胞，说明颈动脉神经中至少含有由颈前神经节的节后纤维和经由颈交感干神经节的节前与节后纤维。颈动脉颈神经在第１５～１６颈椎段从两侧颈长肌缝中走出分布于皮下。

There were two forms of the distribution of the N.caroticus cervicalis on the common carotid arteries in seese.One formed a plexus with some ganglions,the other with none. Degenerated cells were located in both cranialcervical ganglion and some ganglions of the cervical sympathetic trunk after the N.caroticus cervicalis was cut. Accodinly,it was indicated that there were both the postganglionic fibers given by cranial cervical ganglion and pre_ and postganglionic fibers come from the cervical sympathetic trunk.The N.caroticus cervicalis left the carotid sulcus at the level of No.15 or 16 cervical vertebrate and entered the cervcal fascia.
