There are three basic layers in the skin - the epidermis, the dermis and the hypodermis.

The subcutaneous tissue (known as the hypodermis or the third layer of the skin) flattens.

The hypodermis is a subcutaneous layer that consists mostly of fat and provides both insulation and cushioning.

Results: The epidermis and adnexae, the collagen bundles of the dermis and the hypodermis could be identified through architectural and cellular details.

The underlying skin (corium or hypodermis) consists chiefly of connective tissue, contains numerous blood-vessels and nerves, and has a totally different origin.
