What (who) is optic vesicle - definition
Optic vesicle
SACS THAT PROTUDE FROM THE EMBRYONIC FOREBRAIN TO FORM THE EYES
Optical vesicle; Optic vesicles
The eyes begin to develop as a pair of diverticula (pouches) from the lateral aspects of the forebrain. These diverticula make their appearance before the closure of the anterior end of the neural tube; after the closure of the tube around the 4th week of development, they are known as the optic vesicles.

BULGE-LIKE FEATURES OF THE EARLY NEURAL TUBE DURING EMBRYONIC BRAIN DEVELOPMENT
Vesicle (brain development); Vesicle (embryology); Brain vesicles; Primary brain vesicles; Secondary brain vesicles
Brain vesicles are the bulge-like features of the early development of the neural tube in vertebrates. Vesicle formation begins shortly after anterior neural tube closure at about embryonic day 9.
Optic stalk
EMBRYONIC PRECURSOR TO THE OPTIC NERVE
Optic stalks
The optic vesicles project toward the sides of the head, and the peripheral part of each expands to form a hollow bulb, while the proximal part remains narrow and constitutes the optic stalk.
