The description can be completely overridden using the description parameter, or you can force it to display as though it were on the page of a certain level using the level parameter.

During gastrulation, deuterostome embryos' anus is given first by the blastopore while the mouth is formed secondarily, and vice versa for the protostomes In deuterostomes, the developing embryo's first opening, the blastopore , becomes the anus , while the gut eventually tunnels through the embryo until it reaches the other side, forming an ...
In humans (a deuterostome), the development proceeds differently. The buccopharyngeal membrane is created in the foregut and is perforated during the fourth week of human development, creating the primitive mouth, whereas the cloacal membrane is created in the hindgut and is perforated during the eighth week of human development, creating the ...
