Blastoporic is a term used in embryology to describe the opening that forms during gastrulation, which eventually becomes the anus or mouth depending on the animal. There are several synonymous terms that can be used to describe this developmental opening such as blastopore, protostome, deuterostome, and blastoporal. These words are often used interchangeably in scientific literature, but they can have subtle differences in meaning. For example, protostome and deuterostome refer to two different modes of animal development, while blastopore and blastoporal refer specifically to the opening that forms during gastrulation. Regardless of which term is used, understanding the developmental process of blastoporic opening is crucial to understanding many aspects of animal development.
