4.)Connective Tissue Membranes: The second of the two major category types of membranes in the body. Connective Tissue Membranes are composed of various types of connective tissue; no epithelial cells are present in this type of membrane.

5.) Cutaneous Membrane: One of the three types of epithelial membranes. Cutaneous Membrane, also known as skin, is the primary organ of the Integumentary system.

6.) Serous Membrane: Another of the three types of epithelial membranes. Serous Membrane is composed of two distinct layers of tissue. It’s sole purpose is to line the body cavities and cover the surface of organs.

14.) Parietal peritoneum: Lines the walls of the abdominal cavity.

15.)Pleurisy: A pathological condition characterized by inflammation of the serous membranes (pleura) that line the chest cavity and cover the lungs.
