which type of membrane contains fluid between the visceral and parietal layers?
serous membrane
section::::structure.









































a serous membrane (also referred to as a serosa) is one of the thin membranes that cover the walls and some organs of the thoracic and abdominopelvic cavities. serous membranes have two layers. the parietal layers of the membranes line the walls of the body cavity (pariet- refers to a cavity wall). the visceral layer of the membrane covers the organs (the viscera). between the parietal and visceral layers is a very thin, fluid-filled serous space, or cavity.









































section::::structure.:visceral and parietal layers.









































each serous membrane is composed of a secretory epithelial layer and a connective tissue layer underneath.

at the end of the third week, the neural tube, which is a fold of one of the layers of the trilaminar germ disc, called the ectoderm, appears. this layer elevates and closes dorsally, while the gut tube rolls up and closes ventrally to create a “tube on top of a tube.” the mesoderm, which is another layer of the trilaminar germ disc, holds the tubes together and the lateral plate mesoderm, the middle layer of the germ disc, splits to form a visceral layer associated with the gut and a parietal layer, which along with the overlying ectoderm, forms the lateral body wall. the space between the visceral and parietal layers of lateral plate mesoderm is the primitive body cavity. when the lateral body wall folds, it moves ventrally and fuses at the midline. the body cavity closes, except in the region of the connecting stalk. here, the gut tube maintains an attachment to the yolk sac. the yolk sac is a membranous sac attached to the embryo, which provides nutrients and functions as the circulatory system of the very early embryo.
