Function of the Skin
The skin is more than just external covering. It acts as a sensitive boundary between our bodies and the environment. The skin has several important functions, for example: Protection, temperature regulations, waste removal and sense of touch.
Protection
• The skin acts as a protective organ. The film of sebum and sweat on the surface of the skin (acid mantle). It acts as an anti-bacterial agent to help prevent the multiplication of micro-organisms on the skin.
• The fat cells in the subcutaneous layer of the skin help to protect bones and major organs form injury.
• At the basal cell layer of the skin melanin is produced to help protect the body from harmful ultra-violet radiation.
• The horny layer of the

The Subcutaneous tissue – This is the fatty layer of the skin. Lipocytes cells produce lipids. It protects the muscles, bones and internal organs from being damaged and provides insulation and energy for the body when needed.
Function of the Nail
The nails are formations of hardened growths that are based on the protein keratin. The cells in the matrix reproduce to form the nail plate and they multiply gradually pushing up before they harden. This process is called keratinisation. The matrix needs a good supply of oxygen and nutrients for the cells to be able to reproduce.
• Matrix – Reproductive part of the nail, which new nails are formed. This section of the nail contains nerves, blood and lymph vessels.
• Mantle – Helps protect the matrix cells from getting damage.
• Nail bed – It supports the nail plate. The nail bed is supplied with many blood vessels which provide the necessary nourishment.
• Lunula (half moon) – This is the visible section of the matrix. It is commonly referred to as the bridge between the living matrix and the horny nail plate. The lunula forms the upper part of the matrix; it is part of the growing area.
• Nail Plate – This part of the nail consists of three layers of dead keratinised cells. The nail plate is the hardened translucent outer layer.
• Nail Wall – It is the fold of skin that overlaps the nail to form a frame and
Your skin has three layers: the epidermis, dermis, and subcutaneous fat. I feel wonderful knowing that part of my skin is literally fat, don't you?

The Integumentary system is defined as “an organ system consisting in the skin, hair, nails, and exocrine glands” (Integumentary System, 1999). This systems main purpose is to protect the body from the environment around it. The skin covers and protects tissues, nerves, veins, and muscles of the body. The hair and nails give extra strength in reinforcing the skin while keeping the body warm and protecting the skin from harmful UV rays. The exocrine glands of the skin include the sudoriferous glands, sebaceous glands, and the ceruminous glands. Each exocrine gland has a different function as well as location in the skin. The following text will explain the effects of melanoma on the integumentary system.
The integumentary system also known as skin; surrounds the entire human body therefore being the largest organ. The skin and its annexes like hair, sweat glands, sebaceous glands, nails, etc. The main functions of the integumentary system is to function as a protective barrier, that keeps our body free from intrusion of foreign materials, microorganisms and prevents dehydration as well as protecting from desiccation and there are other functions also helps in elimination of waste products and in the regulation of our body tempeture. There are many other functions of the integumentary system and each organ involved in this system has its own particular use
The skin is the largest organ of the body and it acts as a waterproof protector for all of the internal organs, it is comprised of several layers including the Epidermis which is the outer layer and is a protective multi-layered self renewing structure which varies in thickness depending on which part of the body it covers. Under this is the Dermis, this is a layer of connective tissue which provides the skins elasticity and strength, it also contains sensory nerve endings, blood and lymph vessels, sebaceous and sweat glands. Under this layer is the Subcutaneous fat layer, this layer separates the skin from the underlying bone and muscle with a rich blood supply it also serves as an insulator and energy store. Pressure ulcers develop
The skin is the body's greatest organ, and it serves as a guarding deterrent. Its wellbeing and surface appearance are controlled by common components and furthermore the limit of the parts that incorporate the layers underneath
nails. The skin will develop erythema migrans (EM) twenty percent of the time; however, as
“The skin is the largest, most visible, and most complicated of the body systems. In an average adult, it covers more than 3,000 square inches and weighs about six pounds. It is served by one third of all the blood circulating the body” (Saxon, 2010, p. 17).The skin has many functions in which one needs in order to stay healthy and living. The skin protects the underlying tissues and structures of one’s body, and prevents them from drying or obtaining an excessive loss of water and electrolytes. It also regulates the temperatures in the body through mechanisms such as sweating and shivering. Acting as a physical, chemical, and biological barrier, the skin protects from harmful bacteria and foreign substances contacting with the body. Most importantly,
The skin is one of the body’s largest and multifunctional organ. Depending on body size and mass it can weigh between 7 to 22 pounds (1). The skin’s roles are: protection from microbes and harmful substances, thermoregulation and sensation receptiveness of touch, heat and cold. The skin consists of three layers: the epidermis, dermis and the hypodermis. The outermost layer of skin, the epidermis, provides a waterproof barrier and consists of melanocytes. Melanocytes produce and store the pigment melanin which creates skin tone. Underneath the epidermis is the dermis; it contains tough connective tissue, hair follicles and sweat glands. The dermis has an arrangement of nerve fibers and blood vessels. Blood vessels carry nutrients and oxygen to the cells of the dermis and the epidermis, which are avascular (2). The
The vertebrate integumentary system is responsible for protection and thermoregulation. The skin covers the human body and also has appendages like hair and nails that all serve to protect the body from damage. The outer layer of the skin, the epidermis serves as a water resistant barrier protecting the body from absorption and leaking while we are swimming or when it is raining. This maintains homeostasis. This means that when we submerge ourselves in water we do not fill up with water and we also do not leak water. The skin serves to protect the body against pathogens and even damaging UV radiation too. The blood vessel and nerves in the dermis serve to warn us when we are in danger by signaling pain when the sun beats too much on a body
They appear when the nail gets lifted from the surface of the skin beneath it (known as nail bed), after there is an excessive pressure or just any kind of trauma on the nail.
A broken or fractured is a common injury that usually takes a few weeks, or sometimes months, to heal. The matrix is a small area of living tissue directly under the proximal nail fold. All the nail cells grow in the matrix, and if this is damaged in any way, the effects of the damage can be visible on the nail
Stratum Corneum this layer is the outer most layers; it is formed from numerous layers of compressed scale- like, overlapping cells. What makes up the surface of the skin is corneocytes, which are commonly called ‘dead skin cells’. Keratinocytes are found in the epidermis they travel up through the layer where they are formed into corneocytes. The stratum corneum layer protects against lights, chemicals, water loss, heat and bacteria.
The function of the epidermis is to provide a physical barrier between the body and the environment
Providing ourselves with a kit of these specified materials will allow us to fix our broken nails in a flash when the time is right. The advantage of having our own materials requires that it permits us to get more practice fixing our own nails at home and prevents us from going out with red sore fingers that may happen at nail salons. A little bit of nail maintenance can go a long way, but sure enough we will be owing our friends with glowing be dazzled nails. Although, we may not be an expert ourselves; practicing and thinking we can become one will allow us to fix other peoples’ nails when they have the same problem in dealing with broken rusty nails. We are now ready to begin the nail enhancement process.
