The primary action of the inferior rectus muscle is to depress the eye, causing the cornea and pupil to move inferiorly. The inferior rectus originates from the annulus of Zinn and courses anteriorly and laterally along the orbital floor, making an angle of 23 degrees with the visual axis. This angle causes the secondary and tertiary actions of the inferior rectus muscle to be adduction and extorsion (excycloduction).
