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.
Closure of the choroid fissure in the optic stalk occurs during the seventh week of development. The former optic stalk is then called the optic nerve.[1] The Bottom Line: the optic stalks are the structures that precede the optic nerves embryologically.

- The prophenoloxidase activating system is an important innate immune response against microbial infections in invertebrates. The major enzyme, phenoloxidase, is synthesized as an inactive precursor and its activation to an active enzyme is mediated by a cascade of clip domain serine proteinases. In
