滑車神經(英語:Trochlear nerve)是第4對腦神經,編號Ⅳ。[1]

滑車神經為運動性神經,起於中腦下丘平面對側滑車神經核,自中腦背側下丘方出;自腦發出後,繞過大腦腳外側前行,穿經海綿竇外側壁向前,經眶上裂,越過上直肌上瞼提肌向前內側行,進入並支配上斜肌

滑車神經是腦神經中最細的神經。

  1. ^ A technical exception to this rule occurs in the nucleus of the third cranial nerve. The oculomotor nuclear complex contains subnuclei for each of the ocular muscles that it innervates. Axons from one of these subnuclei, the medial nucleus, decussate before exiting the nucleus itself. The medial nucleus of the oculomotor nuclear complex controls the contralateral superior rectus muscle. Cf. Aktekin M, Aldur MM, Bayramoglu A, Atasever A, Ozturk AH, Basar R.
