The skin is divided into three different parts including the epidermis, dermis, and hypodermis. The epidermis is the outermost layer of the skin. This region of the skin has no blood cells or blood vessels running through it. All of the nutrients that the epidermis needs are received through diffusion from the dermis. The epidermis is made up of stratified squamous epithelial cells. The epidermis is made of five separate layers: the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and the stratum corneum. Starting at the innermost layer, the stratum basale is where mitosis of keratinocytes takes place. This layer of the epidermis also contains melanocytes which give the skin it’s pigment. As mitosis takes place in the stratum

The three layers that make up healthy skin: Epidermis, Dermis and Hypodermis. Epidermis is composed of keratinized, stratified squamous epithelium. This layer provides a thick, water proof protective covering over the underlying skins. The dermis layer is composed of primarily of dense, irregular, fibrous connective tissue that is rich in collagen and elastin. The dermis contains blood vessels, nerve ending, and epidermally derived cutaneous oranges such as sweat glands, sebaceous glands and hair follicles. The last layer is Hypodermis this layer is composed primarily of loose dead skin. The fat layer provides cushioning and insulation for

The Skin has numerous functions as it serves as a protective barrier, regulates body temperatures, controls water retention, and secretes sweat and so on. The anatomy of skin can be broken down into three different layers which include; the epidermis, dermis, and the subcutaneous tissue also known as the hypodermis. The purpose of this paper is to explain the relationship between the layers of skin and friction skin

There are three primary layers of the skin: the outer layer, the epidermis and the layer beneath, the dermis and the hypodermis. The epidermis is thin, tough and waterproof while protecting the body from outside bacteria invading the body. It also contains keratinocytes which are from the basal layer which is the deepest layer of the skin. The keratinocytes reach up to the epidermis, shed and new ones form again. The dermis is the second layer of the skin and is the thickest. It is made from fibrous and elastic tissues which are made from fibrillin, elastin and collagen to create the strength and flexibility. It also contains sweat and oil glands, nerve endings, blood vessels and hair follicles. Sweat glands help the body cool off during heat

The skin is part of the integumentary system, and it is the largest organ in the body (Human Anatomy Book, 119). The integument is made up of two layers: the epidermis and the dermis; deep to the dermis, however, is the hypodermis. The hypodermis is not part of the integument, but it is still taken into consideration as the deepest layer of the skin (Human Anatomy Book, 119). The epidermis, being the most superficial part of the skin, consists of five different layers: stratum basale, stratum spinosum, stratum granulosum, stratum lucidum (in thick skin only), and stratum corneum. The stratum basale, however, consists of many cells, one of them being melanocytes (Human Anatomy Book, 121). These cells are responsible for the production of melanin,

The skin is the largest organ of the body, the skin protects us from microbes and the elements, it also helps regulate body temperature, and permits the sensations of touch, heat, and cold. There are three layers of skin, this includes the epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone, the dermis, beneath the epidermis, contains tough connective tissue, which gives the skin flexibility and strength, hair follicles, produce the various types of hair found throughout our body, sweat glands, these produce sweat in response to stress and heat, blood vessels of the dermis are what help regulate our body temperature, and nerve ending, which sense pain, pressure and temperature and the hypodermis, the deeper internal tissue is made of fat and connective tissue, this functions as a protective shield for

“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

Skin and its derivatives make up the integumentary system which acts as a barrier between the body and the outside world. Skin has physical, mechanical, chemical, and immunologic components which allow for body temperature regulation, protection against pathogens, cutaneous sensation, and metabolic functions. When the structural integrity of skin is compromised, its functions are impaired leading to major disability or even death.

Forms the external body covering; protects deeper tissues from injury; synthesizes vitamin D; location of cutaneous receptors (pain, pressure, ect.) and sweat and oil glands.

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

Body temperature regulation * Vitamin D synthesis * Sensation to touch, pressure, pain and temperature * 2 main regions: * epidermis * 5 strata * corneum * top layer, cornified layer, layers of dead cells and soft keratin * lucidum * granulosum * spinosum * basale * deepest layer, contain melanocytes

Its purpose is to keep pathogens and other harmful substances out. The skin is very thin but is considered the largest organ in the body. The epidermis is another major part of the anatomy. It is the top of the skin and is 40-50 rows of dermis cells. The skin system’s basic function is to protect the body from disorders and diseases such as herpes, sunburns and cold sores. the body parts that are included in the integumentary system are hair, skin, nails and exocrine glands. It works with the other body systems by helping the digestive system absorb vitamin D and the immune system helps the integumentary system by preventing and viruses/bacterias from entering the bloodstream and harming the tissues and

The skin is made up of two layers: the epidermis and the dermis. The epidermis consists of keratinocytes, melanocytes, dendritic cells, and tactile cells (Marieb & Hoehn 153). The epidermis consists of four to five layers, including stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. The deepest layer, stratum basale lies on top of the dermis and contains mitotic cells that help repair the skin when it is damaged (Marieb & Koehn 153). Stratum spinosum is the house for Langerhan’s cells, and can be characterized as the “prickly layer” on top of the stratum basale (Poonawalla & Diven). Stratum granulosum is where keratinization begins, and the cells will flatten and the organelles will die (Marieb & Koehn 153). The next layer is the stratum lucidum, which is only in thick skin. The most superficial layer of the epidermis is the stratum corneum, and it is made up 20-30 dead cell layers that help give the skin its protective function (Marieb & Koehn 154). The epidermis is avascular, meaning this layer contains no blood vessels. Each epidermal layer has its function and they work together when repair is needed and they protects the underlying dermis structures.

Dermis The dermis is another layer of skin found under the epidermis. The dermis is made of connective and nervous tissue, blood, and blood vessels. The dermis gives the skin its strength and elasticity. There are two regions in the dermis: the papillary layer and the reticular layer.
