Detailed explanation-2: -Three of these cranial nerves, cranial nerve III (3), cranial nerve IV (4) and cranial nerve VI (6) are responsible for all of the eye’s movements. Problems with these nerves can cause issues with eye position and movement including eyes turning in, turning out, or being vertically misaligned or causing double vision.

Detailed explanation-3: -The trigeminal nerve is the largest of the cranial nerves and provides sensory and motor innervation to the muscles of mastication. [1] More specifically, the sensory information conducted by this nerve includes touch, pain, and temperature.
