Another name for the serosa is the serous membrane.
The serosa, or serous membrane, is a single layer of simple squamous epithelium called mesothelium. This layer is supported by a thin underlying layer of loose connective tissue rich in blood vessels, lymphatic vessels, nerves, and adipose tissue (as stated in the provided reference). Therefore, the terms "serosa" and "serous membrane" are interchangeable when referring to this anatomical structure.
