The reason the hypodermis acts as a shock absorber is that it has no delicate nerve endings and can therefore absorb more shock the major part of its makeup is adipose, which serves as an effective shock absorber the cells that make up the hypodermis secrete a protective mucus it is located just below the epidermis and protects the dermis from shock.

The correct answer will be- the major part of its makeup is adipose, which serves as an effective shock absorber.

Explanation:

The hypodermis is the innermost layer of the skin close to the muscles also known as the subcutis layer.

The subcutis layer is the is made up of fat and collagen which both help the layer to act to conserve the body's heat and also act as a shock absorber which protects the inner organs.

Since the layer contains three types of cells mainly adipose cells, macrophages and fibroblasts where adipose help absorb the shock therefore, the selected option is the correct answer.
