Which membrane attaches at the limbus and separates the inner orbital structures from the outside?

Conjunctiva is the mucous membrane that begins at the limbus, the border where the cornea meets the sclera, and extends over the sclera to cover the inner surface of the eyelids. It forms the outer covering of the eyeball, creating the barrier that separates internal ocular tissues from the outside world while helping keep the surface moist. The cornea is the clear front part of the eye that meets the sclera at the limbus but is not a membrane that attaches there; endothelium is the inner cell layer of the cornea, and the ciliary body is located inside the eye, not forming the external boundary at the limbus.
