Classification
Nouns denoting animals.
Examples
- The optic cup develops from the optic vesicle during embryonic development of the eye, eventually forming the retina.
- In the fourth week of human embryonic development, the optic vesicle invaginates to form the optic cup.
- Studies on animal models have shown that genetic mutations affecting optic cup formation can lead to congenital eye disorders.
- The optic cup consists of two layers: the outer pigmented layer and the inner sensory layer, which will eventually differentiate into the adult retina.
- During embryonic development, the optic cup undergoes a series of morphogenetic changes to give rise to the adult retinal structure.
