Abstract
The trochlear nerve is the fourth cranial nerve (CN IV) and one of the ocular motor nerves that controls eye movement. The trochlear nerve, while the smallest of the cranial nerves, has the longest intracranial course as it is the only nerve to have a dorsal exit from the brainstem. It originates in the midbrain and extends laterally and anteriorly to the superior oblique muscle.
摘要
滑车神经是第四对脑神经（CN IV），是控制眼球运动的眼运动神经之一。滑车神经虽是脑神经中最小的，但因其是唯一从脑干背侧穿出的神经，所以具有最长的颅内行程。它起源于中脑，向外侧和前方延伸至滑车神经支配的上斜肌。
