What component contributes to both bodily contour and energy storage?

1. Dermis

2. Papillary layer

3. Subcutaneous layer

4. Corneous layer

The correct answer is: Subcutaneous layer

The subcutaneous layer, also known as the hypodermis, plays a critical role in both bodily contour and energy storage. This layer is situated beneath the dermis and is primarily composed of loose connective tissue and adipose (fat) tissue. The adipose tissue within the subcutaneous layer acts as a reservoir for energy, storing fats which can be utilized by the body when needed. Additionally, the thickness of this layer contributes to the overall shape and contour of the body, influencing how we perceive the body's form. In contrast, the dermis primarily provides structural support and elasticity to the skin, while the papillary layer refers specifically to the upper portion of the dermis that interfaces with the epidermis and plays a role in providing nutrients to the epidermis and housing sensory receptors. The corneous layer, or stratum corneum, is the outermost layer of the epidermis which primarily serves as a protective barrier rather than contributing to bodily contour or energy storage.
