Key Concepts

Cleavage

Cleavage is the series of rapid cell divisions in the early embryo, where the zygote subdivides into smaller cells called blastomeres without increasing the overall size. This process establishes the basic cellular makeup needed for further developmental stages.

Blastula

The blastula stage is characterized by the formation of a hollow ball of cells surrounding an inner fluid-filled cavity called the blastocoel. This stage is preparatory, setting the groundwork for later events such as gastrulation, but does not involve the formation of the gut.

Gastrulation

Gastrulation is a critical process in embryonic development during which the single-layer embryo reorganizes into a three-layered structure, forming the ectoderm, mesoderm, and endoderm. These germ layers give rise to all of the tissues and organs in the body.

Neurulation

Neurulation is the developmental stage in which the neural plate forms and folds into the neural tube, eventually giving rise to the central nervous system, including the brain and spinal cord. This process is vital for proper nervous system formation.
