Which connective tissue combines with adipose tissue to form the subcutaneous layer that attaches the skin to underlying structures?

The connective tissue that combines with adipose tissue to form the subcutaneous layer is called the superficial fascia, also known as the hypodermis or subcutis. It is a layer of tissue located directly beneath the skin, serving as a connection between the skin and underlying structures such as muscles and bones.

To find this answer, you can use various resources such as textbooks, medical websites, or anatomy reference books. By researching the layers of the skin and its different components, you can identify that the superficial fascia is the connective tissue that binds the adipose tissue to the skin, forming the subcutaneous layer.
