The hypodermis contains mostly fat, connective tissue, and elastin, which is an elastic protein that helps tissues return to their normal shape after stretching. Subcutaneous tissue also provides the skin with nerves and blood supply. It is not technically part of the skin, but it helps attach the skin to the bones and muscles. The deepest layer of the skin is the subcutaneous tissue, the hypodermis, or the subcutis. Protein fibers in the reticular region give the skin its strength and elasticity. The reticular region contains dense, irregularly organized connective tissue.

These projections give the dermis a bumpy surface and are responsible for the patterns of a person’s fingertips. It has finger-like projections that push into the epidermis. The papillary region contains loose connective tissue. The dermis further splits into two layers: Papillary region This will show up later as stretch marks. If the dermis stretches a lot, such as during pregnancy, then it can tear. The dermis also contains the receptors that detect pressure (mechanoreceptors), pain (nociceptors), and heat (thermoreceptors). It is home to a number of glands, including sweat glands and sebaceous glands, which produce sebum, an oil that lubricates and waterproofs hair. The reason the dermis can perform these functions is that it houses the hair follicles, blood vessels, and lymphatic vessels. to provide sensation and blood to the skin.It also gives the skin strength and elasticity. The dermis serves as connective tissue and protects the body from stress and strain. These are found in the epidermis and protect the skin from UV rays.Ī thin sheet of fibers known as the basement membrane divides the epidermis and the dermis. The color of the skin comes from a pigment called melanin, which is produced by melanocytes. Their job is to act as a barrier against bacteria, parasites, fungi, viruses, heat, ultraviolet (UV) rays, and water loss. Keratinocytes are the most common type of cells within the epidermis. Over the course of around four weeks, these cells make their way to the surface, become hard, and replace the shedding, dead cells. The epidermis constantly makes new cells in its lower layers. In fact, the outermost parts of the epidermis consist of 20–30 layers of dead cells. Humans shed around 500 million skin cells each day.

to protect the body from the external environment.It is a waterproof barrier that gives skin its tone. The skin has three basic layers - the epidermis, the dermis, and the hypodermis.
