The optic stalk is a structure that connects the developing eye to the brain during embryonic development. While it is typically referred to as the optic stalk, there are a few synonyms that can also be used in scientific literature. One of those synonyms is the optic nerve stalk or nerve fiber layer, which describes the nerve fibers that make up this structure. The term retinal stalk can also be used, specifically referring to the part of the optic stalk that connects to the retina. Additionally, the term optic nerve head can be used to describe the point where the optic stalk enters the cranial cavity and becomes the optic nerve.
