Detailed explanation-1: -The trochlear nerve is one of 12 sets of cranial nerves. It enables movement in the eye’s superior oblique muscle . This makes it possible to look down. The nerve also enables you to move your eyes toward your nose or away from it.
Detailed explanation-2: -Trochlea is Latin for pulley, which appropriately describes the sling of connective tissue that houses the tendon of the superior oblique. Moreover, the trochlear nerve is a somatic efferent (motor) nerve, and along with oculomotor (III) and abducens (VI) nuclei, it is responsible for eye movement.
