What is another term for the cutaneous membrane?

  1. Dermis

  2. Skin

  3. Mucosa

  4. Serosa

The correct answer is: Skin

The cutaneous membrane is another term for the skin, which serves as the body's primary barrier and protective layer. This membrane is composed of two main layers: the epidermis, which is the outer layer, and the dermis, which lies beneath it and contains connective tissue, blood vessels, and other structures. The skin plays a critical role in regulating temperature, providing sensation, and protecting underlying tissues from injury and infection. The other options refer to different types of membranes in the body. Dermis specifically indicates the inner layer of the skin, while mucosa refers to the moist lining of various body cavities and internal organs. Serosa denotes the smooth membrane that lines certain cavities of the body and covers organs. Understanding the terminology and function of these membranes aids in comprehending their respective roles in human anatomy and physiology.
