What are the Layers of the Skin?

The skin comprises three main layers, each with distinct histological features:
- Epidermis: The outermost layer, primarily composed of keratinocytes, and includes several sub-layers such as the stratum corneum, stratum granulosum, stratum spinosum, and stratum basale.
- Dermis: Located beneath the epidermis, it contains collagen and elastin fibers, blood vessels, nerve endings, hair follicles, and sweat glands.
- Subcutaneous Tissue: Also known as the hypodermis, this layer is made up of adipose tissue and connective tissue, providing insulation and cushioning.
