Related to mesogleal: Gastrodermis
a structureless gelatinous substance in lower multicellular diploblastic animals (sponges and coelenterates) that is released by the ectoderm and endoderm and fills the space between the two. In jellyfish and ctenophorans, the mesoglea is thoroughly saturated with water (about 97.5 percent). The mesoglea of sponges contains amoeboid and germ cells, cells that form skeletal elements, and other cells that impart to it the quality of loose parenchyma.
