GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -The inner (visceral) layer of the serous pericardium lines the outer surface of the heart itself. Between the two layers of the serous pericardium is the pericardial cavity, which contains pericardial fluid. It is this fluid that provides lubrication between the two layers, and allows the heart to expand and contract.

Detailed explanation-3: -The name of the serous membrane that covers the heart is called the visceral pericardium.

Detailed explanation-4: -Parietal serosa line the body cavities and visceral serosa line the outer part of the organs within the body cavity. Therefore, parietal serous membranes are the outer membranes lining a body cavity and visceral serous membranes are the inner membranes lining a body cavity.

Detailed explanation-5: -The serous membrane, or serosal membrane, is a thin membrane that lines the internal body cavities and organs such as the heart, lungs, and abdominal cavity. The thin membrane is made up of mesothelium tissue which originates from the mesoderm.
