Question

Which term is used when discussing the outer layer of the skin?

Answers

  1. Dermis
    • Rationale:

      The dermis, or corium, is the second layer of skin that lies between the epidermis and the hypodermis. The thickest layer of the skin, the dermis is made of elastic and fibrous tissue; therefore, it provides the skin with flexibility and strength.

  2. Epidermis
    • Rationale:

      The epidermis is the outermost layer of the skin. It is the first line of defense from environmental threats.

  3. Adipose tissue
    • Rationale:

      Adipose tissue is contained in the hypodermis, or subcutaneous layer of the skin. It is not an actual layer of skin.

  4. Subcutaneous layer
    • Rationale:

      The innermost layer of the skin is the hypodermis (i.e., subcutaneous layer). This layer of skin functions as padding or insulation for the body.

Overview

The skin has three basic layers. Each layer plays a role in defending the body against environmental threats.

Explanation

Learning Outcomes

The three layers of the skin include the epidermis, the dermis, and the hypodermis. The epidermis is the outermost layer of the skin. The next layer is the dermis. The innermost layer of the skin is the hypodermis or subcutaneous layer. Adipose tissue is contained in the hypodermis.
