The orbital part encircles the bony orbit of the eye. It is primarily responsible for forcefully closing the eyelids. This happens when squinting or tightly closing the eyes.

Palpebral Part: The palpebral part originates from the medial palpebral ligament and is located within the eyelids. This part allows the eyelids to close gently. It functions during blinking and when the eyes are closed lightly.

It compresses the lacrimal sac, which facilitates the flow of tears across the surface of the eye.
