comment [de]	tritt als einziger Kopfnerv dorsal aus dem Hirnstamm aus (kaudal der Vierhügel), zieht seitlich-vorn durch die Dura am vorderen Tentorium-Ursprung und in der lateralen Wand des Sinus cavernosus und durch die Fissura orbitalis superior in die Augenhöhle zum Musculus obliquus superior oculi

label [med]	Nervus trochlearis [IV]
comment [en]	Supplies the superior oblique muscle of the eye; its origin is in the midbrain below the cerebral aqueduct, its fibers decussate in the superior medullary velum, and emerge from the brain at the side of the frenulum, the only cranial nerve to arise from the dorsal aspect of the brain stem; it therefore has the longest intracranial course, entering the dura in the free edge of the tentorium, close to the posterior clinoid process, and passing in the lateral wall of the cavernous sinus to enter the orbit through the superior orbital fissure
