Epidermis

Subcutaneous layer (hypodermis)

Sebaceous glands

Dermis

Previous problemNext problem

Verified step by step guidance

Understand the function of each structure listed in the options: The epidermis is the outermost layer of the skin, primarily responsible for protection and preventing water loss. The dermis lies beneath the epidermis and contains connective tissue, blood vessels, and nerves, providing strength and elasticity. Sebaceous glands produce sebum, an oily substance that lubricates the skin and hair. The subcutaneous layer (hypodermis) is composed of fat and connective tissue, providing insulation, cushioning, and contour to the body.

Focus on the key terms in the question: 'smoothness,' 'contour,' and 'protective cushion.' These terms suggest a structure that contributes to the shape of the body and provides padding to protect underlying tissues.

Identify the structure that matches these functions: The subcutaneous layer (hypodermis) is primarily responsible for giving the body smoothness and contour due to its fat deposits. It also acts as a protective cushion for the skin by absorbing shocks and insulating the body.

Eliminate incorrect options: The epidermis and dermis do not provide significant contour or cushioning. Sebaceous glands are involved in lubrication but do not contribute to body shape or protection.

Conclude that the correct answer is the subcutaneous layer (hypodermis), as it aligns with the functions described in the question.
