Quick Summary

Centrolecithal yolk refers to eggs where the yolk is concentrated near the center of the egg, a characteristic found in arthropods. This yolk serves as the nutritive material for a developing embryonic animal. While some eggs have uniformly distributed yolk (isolecithal) or yolk concentrated in one hemisphere (telolecithal), centrolecithal eggs are distinct in their yolk distribution. In vertebrates like amphibians and birds, the yolk sac is large and provides nourishment. However, in humans and other true mammals, there is very little yolk, and the yolk sac is a temporary structure that detaches early in development.12
