What is the name of the outer layer of skin?

The outer layer of the skin is known as the epidermis. However, the choice that refers to the outer layer in the context of the skin is the dermis. The dermis is the layer located beneath the epidermis and contains connective tissue, hair follicles, and sweat glands. This layer provides structural support and elasticity to the skin.

The hypodermis, or subcutaneous layer, lies beneath the dermis and is primarily composed of fat and connective tissue, playing a role in insulation and cushioning for the body. Epithelium refers to a type of tissue that covers surfaces and lines cavities in the body, not specifically a layer of skin. Dermatome is a term used in anatomy that refers to an area of skin that is mainly supplied by a single spinal nerve root, rather than a layer of skin itself.

Thus, acknowledging the choices and their functions helps in understanding the structure and classification of skin layers.
