滑车神经

滑车神经为运动性神经,起于中脑下丘平面对侧滑车神经核,自中脑背侧下丘方出;自脑发出后,绕过大脑脚外侧前行,穿经海绵窦外侧壁向前,经眶上裂,越过上直肌上睑提肌向前内侧行,进入并支配上斜肌

滑车神经
The trochlear nerve entering the orbit, seen from above, supplies the superior oblique muscle
The trochlear nerve (CN IV) seen with other cranial nerves. It is the only cranial nerve to emerge from behind the brainstem, and curves around it to reach the front

  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.
