The innermost layer of the skin is the hypodermis, also known as the subcutaneous tissue.
Understanding the Skin's Layers
The skin is a complex organ with three main layers:
- Epidermis: This is the outermost layer, acting as a protective barrier against the environment. Source: Cleveland Clinic - Epidermis
- Dermis: Located beneath the epidermis, the dermis contains connective tissue, blood vessels, hair follicles, and glands. It provides strength and elasticity to the skin. [Source: Reference provided in question prompt]
- Hypodermis: This is the deepest layer, primarily composed of fat cells (adipocytes). It insulates the body, provides cushioning, and stores energy. Source: Cleveland Clinic - Hypodermis, Source: Verywell Health - Hypodermis
It's important to note that some sources may refer to the stratum basale as the innermost layer of the epidermis, but this is a sub-layer within the epidermis, not the innermost layer of the entire skin. Source: Oregon State University - Layers of the Skin
The hypodermis's role in insulation and energy storage highlights its crucial function in maintaining body temperature and overall health. The thickness of the hypodermis varies depending on location and individual factors.
