Final answer:
The orbicularis oculi and levator palpebrae superioris are the two muscles that move the eyelid, with the former closing the eyelid and the latter opening it.
Step-by-step explanation:
The two muscles primarily responsible for moving the eyelid are the orbicularis oculi and the levator palpebrae superioris. The orbicularis oculi is a circular muscle that encircles the eye and functions to close the eyelid. The levator palpebrae superioris is another crucial muscle that aids in the lifting of the upper eyelid, allowing the eye to open. Both muscles work in tandem to control the movement of the eyelids, and they are innervated by cranial nerves, ensuring proper control and coordination of eyelid movements.
