Did you know that there are actually two chalaza in a bird's egg?

Really? I always thought it was just a single part connecting the yolk.

That's fascinating! I love learning about the science behind eggs.

Root Explanation

Chalaza → The word 'chalaza' originates from the Greek 'chalaza' (χαλάζα), meaning 'a hailstone' or 'a lump'. In biological terms, it refers to the twisted strands of protein in an egg that anchor the yolk in place. The term reflects the structure's appearance, resembling a small lump or twist.

Memory Tip

Imagine a 'lump' or 'twist' in an egg that keeps the yolk secure — that's what chalaza refers to.
