解剖學術語

终末神经(英文:Terminal nerve),即第0对脑神经,于1878年由德国科学家古斯塔夫·弗里奇英语Gustav Fritsch鲨鱼大脑中发现,1913-14年在人体发现[1][2][3]。1980年代末,该神经被命名为“第0对脑神经(cranial nerve 0,CN0)”[1]。终末神经的功能并不完全明确,故在解剖学教科书中不常被提及[2][4][5]

结构

[编辑]

终末神经位于其它脑神经稍前方,是一个由无髓鞘的周围神经纤维束组成的微观神经丛[4]。该神经丛在蛛网膜下腔(subarachnoid space),与筛板邻近[4]

由于非常细薄,终末神经在解剖中常被忽视,在开颅过程也中常被撕裂[6]。因此,如要看到该神经,需要小心操作。

功能

[编辑]

尽管与嗅神经邻近,终末神经并不连接嗅觉感受器嗅球[1]。因此,有推测终末神经或为生物的退化结构,亦或是有参与对信息素的感知[1][5]
