The superior oblique muscle, or obliquus oculi superior, is a fusiform muscle in the upper, medial side of the orbit whose primary action is downward, lateral rotation of the eye. One of the extraocular muscles, the superior oblique is the only muscle innervated by the trochlear nerve (the fourth cranial nerve). [ http://en.wikipedia.org/wiki/Superior_oblique_muscle ]

homology notes
  • The ability to rotate the eyeball is common to all vertebrates with well-developed eyes, regardless of the habitat in which they live, so these [extrinsic ocular] muscles tend to be conservative. They change little during the course of evolution.[well established][VHOG]
