第十一脑神经的脊髓部分通常被认为是纯运动神经。然而,多年来人们已经知道,感觉型神经细胞的分散群沿着其颅内根的路径发生,Fahmy('27)最近描述了一个3个月大的人类婴儿的颅外神经节。这种现象的存在似乎是偶然的,因为他在一个成年人和一个7个月大的胎儿身上都没有发现这种现象。1901年,Weigner描述了人类上颈神经的许多解剖,并呼吁注意这些神经的背根与脊髓副之间的各种吻合。在某些情况下,第一颈背根直接从副神经节而不是从单独的神经节传入脊髓。有时在第11根的根部和颅内可见肿胀,切片显微镜下可见大量感觉型细胞。他的结论是,在某些情况下,脊髓副神经不是纯粹的运动神经。Weigner只对那些可见肿胀的神经进行了切片,因此没有证实散在或小群的细胞。在研究了一系列人类胚胎后,Streeter(2005)得出结论,第十和第十一脑神经是大脑的一部分。153.
The spinal portion of the eleventh cranial nerve is usually considered to be purely motor. However, it has been known for many years that scattered groups of nerve cells of the sensory type occur along the course of its intracranial rootlets, and Fahmy ('27) recently described an extracranial ganglion in a three-month-old human infant. The existence of this seems to be occasional, because he failed to find any in an adult and in a seven-month-old fetus. I n 1901, Weigner described numerous dissections of the upper cervical nerves in man and called attention to various types of anastomosis between the dorsal roots of these and the spinal accessory. In some cases the first cervical dorsal root passed to the spinal cord directly from the accessory instead of from a separate ganglion. Sometimes visible swellings were found on the rootlets and intracranial part of the eleventh, and when these were sectioned and examined microscopically, numerous cells of sensory type were found. He concluded that in some cases the spinal accessory nerve is not purely motor. Weigner sectioned only those nerves on which swellings were visible, and for this reason the absence of scattered or small groups of cells was not confirmed. After studying a series of human embryos, Streeter ('05) concluded that the tenth and eleventh cranial nerves are part ' Contribution no. 153.
