Examples of serosa in the following topics:

  • Serosa

    • Serosa consists of a secretory epithelial layer and a thin connective tissue layer that reduce the friction from muscle movements.
    • In anatomy, the serous membrane (or serosa) is a smooth membrane that consists of a thin connective tissue layer and a thin layer of cells that secrete serous fluid.
    • Serosa is not to be confused with adventitia, a connective tissue layer that binds together structures rather than reduces friction between them.
