All statements regarding trochlear nerve are true, EXCEPT?
Trochlear nerve is a crossed cranial nerve. The nucleus of the trochlear nerve supplies the contralateral superior oblique muscle.The trochlear nerve emerges from dorsal surface of the brainstem near the midline, courses anteriorly around the cerebral peduncle and enters the orbit through superior orbital fissure. The trochlear nerve has ceain unique features:It is the only cranial nerve whose fibers originate totally from the contralateral nucleus.It is the only cranial nerve to emerge from the dorsal surface of the brain stem.It is the most slender of all the cranial nerves.It has the longest intradural course among the three extraocular motor nerves.It supplies only one muscle i.e. superior oblique (Abducent cranial nerve also supplies only one muscle i.e. Lateral rectus).
Longest intracranial course
Arises from dorsum of brainstem
Supply ipsilateral superior oblique muscle
Enters orbit through superior orbital fissure outside annulus of Zinn
