The
oculomotor nerve is the third of twelve paired
cranial nerves. It controls the
ciliary muscle[?] (affecting
accomodation[?]), and all
extrinsic eye muscles[?] except for the
superior oblique muscle[?] and the
lateral rectus muscle[?]. In addition, it supplies
parasympathetic[?] fibres to the eye via the
ciliary ganglion[?], and thus controls
pupil constriction[?].
