Skin elasticity question?

Question

I need help with my bio homework. Here is the question. Skin elasticity is associated with spring-like proteins that are located in what layer of the skin? choices are listed below:

1) outer layer of skin (top of epidermis)
2) bottom layer of epidermis where cells divide
3) connection fibrous layer of the dermis
4) fatty layer just below the dermis
5) middle layer of the epidermis

Answer 1

3) connection fibrous layer of the dermis

"The dermis lies below the epidermis and contains a number of structures including blood vessels, nerves, hair follicles, smooth muscle, glands and lymphatic tissue. It consists of loose connective tissue otherwise called areolar connective tissue - collagen, ELASTIN and reticular fibers are present."

The articles state that elastin is responsible for skin elasticity, and that it is contained in the dermis. Choice 3 is the only choice that contains the dermis as an answer.
