The lamina papyracea, also known as the orbital lamina of ethmoid bone, is the principal component of the medial wall of the orbit, and also the lateral surface of the ethmoid sinuses.

Gross anatomy

It articulates:

superiorly with the orbital plate of the frontal bone
inferiorly with the maxilla and orbital process of the palatine bone
anteriorly with the lacrimal bone
posteriorly with the sphenoid bone

It thickens posteriorly to form the optic tubercle, protecting the optic nerve.

Etymology

Lamina papyracea is latin for paper-thin, which is an appropriate term to describe this thin sheet or paper-like osseous structure.
