Question

Quizplus · Accepted Answer

The first vestiges of eyes in the embryo are called optic vesicles, which eventually form the optic cups and give rise to the retina, lens, and other components of the eye. Mesenchyme refers to a type of embryonic tissue that gives rise to various structures in the body, but is not specifically related to eye development. Optic discs are areas on the retina where the optic nerve exits the eye and do not form until later in development. Optic cups are the result of the invagination of the optic vesicles and occur after the initial formation of the vesicles.
