The Layer Of The Skin

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

Skin is the largest organ on the body. It has two layers: the thin outer layer is made up of dead skin cells that are constantly shed and replaced by new cells. The thick inner layer is made up of blood vessels, nerves, and hair follicles, which contain glands. The glands in the hair follicles produce an oily substance called sebum, which keeps the skin and hair from drying out. Daily washing will keep the skin on the face and other areas of the body clean by removing the dirt, oil, and dead cells before they can accumulate.

The outer germ layer is the ectoderm that forms the outer part of the body (the skin) and the nervous system. The endoderm, the inner germ layer, forms many inner structures, including the digestive tract and many glands associated with it. Lastly, the mesoderm is the middle layer which forms much of the skeleton and muscles.

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

Dermis: one of the two layers of cells that form the skin. Specifically, it is the innermost layer.

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 in our body which makes up 20.83 square feet on an adult body.* Integumentary system plays a major role in homeostasis that keeps our body in check. Its main function is to act as a shield from the outside environment. It involves three main layers. *The epidermis, dermis and subcutaneous tissue. Although this organ system is vital, there are many other accessory components that are equally important to the overall health of our body.

There are two layers that make up the iris. The innermost layer is called the iris pigment epithelium and is of neuroectodermal origin. The outer layer is of mesodermal origin and is named the iris stroma. The iris stroma contains connective tissue which holds nonpigmented fibroblasts as well as pigmented melanocytes (Imesch et. al. 1997). Eye

The epidermis is the relatively thin, outer layer of the skin. It provides a waterproof barrier and creates our skin tone. Its also an avascular region of the body, meaning that it does not contain any blood or blood vessels. The epidermis along with other layers of the skin protect internal organs, muscles, nerves, and blood vessels again trauma. The epidermis is divided into five layers. The first layer is called the stratum corneum which is the outmost layer made of dead keratinocytes with a layer of protein around them. The second layer is Stratum lucidum it constitutes the outer epidermal layer and comprises of dead skin cells. The third layer is Stratum granulosum also known as the granular layer, Keratinocytes migrating from the underlying

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.

The elastic membrane that covers the body is also known as the skin. It protects your body from exposure from dangerous things in the environment such as bacteria, it also protects the underlying structures such as the blood vessels, nerves and the organs. The skin is the largest organ in the body. The skin is made up off three layers such as epidermis which is the outermost layer, this consists of cells called keratinocytes which is made from the tough protein keratin.

It has an important role in controlling fluid loss from the body, regulation of body temperature and protection against microorganisms or other external influences (Nestle et al., 2009). The skin comprises three distinct histological layers which are: Epidermis, Dermis and the subcutaneous layer of adipose tissue (Kanitakis, 2002).
