Eyelid muscles

Your eyelids have two muscles, one to open them and one to close them.

The one that closes your eyelids is called the orbicularis oculi.
orbicularis means little circle, and oculi means your eye.

The one that opens your eyelids is the levator palpebrae superioris.
levator means lifter, palpebrae means eyelid, and superioris means above.
