- n. Plural form of chalaza.
Sorry, no etymologies found.
The first thick layer of albumen protein is twisted by spiraling grooves in the oviduct wall to form the chalazae from the Greek for “small lump,” “hailstone”, two dense, slightly elastic cords which anchor the yolk to the ends of the shell and allow it to rotate while suspending it in the middle of the egg.
At the same time, the flexible "chain" - called the chalazae - that holds the yolk in suspension weakens.
The egg yolk is suspended in the egg white known more formally as albumen or ovalbumin by one or two spiral bands of tissue called the chalazae.
In the intact egg, the chalazae allow the germ cell to return to the top whenever the hen rearranges her eggs.
At either end of the yolk (Figure 1, y.) twisted strands of albuminous matter, the chalazae (ch.) keep the yolk in place.
The yolk with is attached embryo is suspended in the center of the egg shell by thick spiral fibers of the albumen called chalazae.
