The dermis is the layer of tissue under the epidermis. The dermis is also called the subcutaneous tissue. The dermis is one of the three layers of the skin. Skin is the only other answer, and it is considered the largest organ of the human body. The three basic layers (from outer/top to inner) are:
Hypodermis, also known as subcutaneous tissue, has important functions. Hypodermis layer lies immediately below the dermis. It is the lowermost layer of our integumentary system. Though hypodermis is not part of the skin, it is very essential for anchoring the skin to the body. Though both dermis and hypodermis are derived from mesoderm, unlike dermis, this layer is not derived from dermatome region. Subcutaneous tissue layer has many types of cells in it like fibroblasts, fat cells (adipocytes) and leukocytes.
