Gastrulation typically occurs during the early stages of animal embryonic development, after fertilization and cleavage have taken place. It involves the reorganization of the blastula into a trilaminar structure known as the gastrula, which sets the stage for the formation of the three primary germ layers (ectoderm, mesoderm, and endoderm).

What develops during gastrulation and will later develop into bone muscle and circulatory structures?
The middle layer is formed during the gastrulation. This layer develops into muscles, bones and blood vessels.
