Defective Cutaneous Wound Healing

The outer most layer of the skin or Epidermis contains stratified squamous, keratinized, epithelial tissue; which lacks blood vessels, and the cells are packed closely together (Sloane, 1994, p.85)

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 dermis contains elastic and fibrous tissues such as fibrillin, collagen and elastin. These tissues gives

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 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

Your skin has two layers. The outer layer is called your epidermis. It's made up of epithelial cells. The main purpose of your epidermis is to protect your body from germs and from getting injured. If we didn't have an epidermis, we'd be sick all the time, and any little cut would hurt extremely bad. On

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 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

Epidermis, dermis, and hypodermis are layers of the human skin. Epidermis is the outer layer of the human skin, dermis is in between the epidermis and the epidermis, and hypodermis is the deepest section of the skin. Epidermis unlike dermis and hypodermis acts as a protective shield for the human body and every 28 days the epidermis is renewed. Dermis is one of the major factors to your skin, it gives the skin structure and resilience to the human skin, unlike the functions of the epidermis and the hypodermis. The hypodermis is what insulates the body from cold temperatures and provides a shock absorption for the human. The all relate because they deal with the human skin but they are all different because they have different functions to better

Carville (2012, p 8) defined epidermis as ‘the outer layer of the skin and is comprised of stratified, squamous epithelial cells or keratinocytes’. Epidermis have also various layers that are divided into 4 or 5 layers, stratum germinativum, stratum spinosum, stratum granulosum, stratum lucidum and stratum corneum, respectively. The first layer of epidermis is the stratum corneum, which is also known as a horny layer. The other layer is stratum lucidum, however this is mostly found in a thicker part of epidermis, such as soles of the feet and palms. The middles layer is the stratum granulosum, which is also known as the granular layer. According to Carville (2012, p 9), it is comprised of one to five cells thick of granular cells that contain keratin and shrivelled nuclei’. The next layer after the stratum granulosum is the stratum spinosum, otherwise known as the prickly layer. ‘The stratum spinosum is made up of several layers of polyhedral shaped cells, which have large oval nuclei’ (Carville 2012, p 9). The last layer of epidermis is the stratum germinativum or commonly known as basal layer. This is a layer where basal cells or keratinocytes develop. In comparison to epidermis, dermis have also layers, these are papillary layer, which is composed of loose connective tissue, and reticular layer, which is mostly composed of dense connective

The Integumentary system additionally referred to as the integument (The skin) is the biggest organ in the body. It has a surface territory of around two Square meters, varies in thickness and incorporates hair and nails. There are two parts to the integument the cutaneous membrane which is the skin and the accessory structures which all originate from within the dermis.(Anderson, 2012, p.3)The structure of the integumentary system is comprised of different layers the epidermis, dermis and subcutaneous layer. The epidermis is the external layer of the skin and is comprised of epithelial cells. The epidermis does not have vessels so it is called avascular. Inside the epidermis are four cell types, Keratinocytes cells give defensive

1. epidermis - it is the most superficial layer of the skin and consists of five layers. The outer layer of the stratum corneum of the epidermis, which consists of keratin proteins, and lipids. When this part of the skin effect elements and other factors such as aging and skin diseases, we can often visible immediate dryness and flaking. The second layer is a layer Spinosum or spiny layer. It is held together with barbed cells and wherein the protein or keratin, synthesized and produced. The next layer is the granular layer where melanocytes, the precursors of keratin found. Melanocytes are responsible for the color, or pigmentation. Lucidum layer is the fourth layer, which is very thin. It is almost exclusively in the hands and soles of the

Epidermis, which is the most superficial part of your skin. It provides waterproofing, protection and secretions to regulate temperature as well it contains melanocytes which produce melanin that pigments your skin. Dermis, the layer deep to the epidermis, contains blood vessels, sensory nerves and accessory organs. Hypodermis, the deepest layer of skin, attaches itself to the underlying muscle.

Under the Dermis, there is a layer of adipose tissue which is called the Subcutaneous layer.This layer helps to maintain the human body temperature stable. This layer of fat acts like a pathway for nerves and blood vessels that go from the Dermis to the muscles. Also, it helps protect and prevents muscle and bones from
