Papilla is a term with various uses in the realm of anatomy . It can be the cone-shaped bump that forms on certain membranes or on the skin from a branch of a vessel or nerve.
A region found in the retina is known as the optic disc. From this space located in the human eye, the axons of the cells that make up the optic nerve depart. Because the optic disc does not have the necessary elements to feel the luminosity, it is also called a blind spot .

The optic disc is not the only disc located in the eye area. The lacrimal papilla , a conical-shaped prominence, is located on the side of the eyelid and houses the start of the tear duct.
