Which of the following statements about the upper eyelid is INCORRECT?

Show Answers

The facial nerve innervates the muscles responsible for closing the eyelid.The muscles that elevate the eyelid receive innervation from a branch of the trigeminal nerve.The sensory innervation of the upper eyelid is provided by the fifth cranial nerve.The lacrimal and ophthalmic arteries supply blood to the upper eyelid.None of the above.

Explanation

The muscles that close the eyelid are innervated by the facial nerve (cranial nerve VII). The sensory supply to the upper eyelid comes from the trigeminal nerve (cranial nerve V). Blood supply is provided by the lacrimal and ophthalmic arteries. However, the muscles that open (elevate) the upper eyelid are supplied by the oculomotor nerve (cranial nerve III), not the trigeminal nerve. Therefore, option B is incorrect.
