Stratum Layer Research Paper

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 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.

Stratum 3 in the Blue Mountain site lacks any evidence of settlement or subsistence; on the other hand, this could be evidence that the people who were there were nomadic rather than sedentary. The 4,534 debitage pieces and 234 cores suggest that it was a hunter-gatherer society and they used local obsidian which means that they could have had no contact with other people and likely did not travel very far. The majority of their tools were also made from the outer part of the cores.

Melanocytes are pigment-producing cells commonly found in your lower part of your outer layer of skin, which is known as the epidermis. The natural color of your skin is produced by melanin. When skin is being exposed to

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 Integumentary System, also known as the skin, is the largest organ of the body. Its complete structure is composed of many different tissues. The skin protects the cow’s body from any bacterial invasions and physical damage. When a cow becomes sick, the skin is the first system that is affected. The integumentary system is composed of three layers: (i) Epidermis, (ii) Dermis, and (iii) Hypodermis or Subcutis. To start with the inner most layer you have the Hypodermis (Subcutis). The Hypodermis consists of connective tissues, elastic fibers and fat. When fat forms a layer of thickness it is called Peniculus Adiposus. Any reserved energy is also stored within the Hypodermis. Then you have the layer, Dermis. The Dermis supports the outer most layer, Epidermis. Dermis consist of collagen, reticular and elastic fibers which plays a large role in the strength and elasticity in the skin; as well as the maintenance and repair of the skin. Lastly, you have the Epidermis. The Epidermis alone consist of four sublayers, (i) Stratum Corneum – outermost horny layer, (ii) Stratum Lucidum – clear layer, (iii) Stratum Granulosum – granular layer, and (iv) Stratum Spinosum – prickly cell layer. The Epidermis is derived from basal membrane Stratum Basale, which presents the openings for the hair follicles. Some of the functions of the skin include: preservation of the cow’s shape, protection from water loss, protection from any physical, chemical and microbial injury imposed by an external agent. An important role of the skin is it balances its Thermoregulation, which is its ability of an organism to regulate its body

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 epithelial skin cell is in the Integumentary System. The Integumentary system is an organ system that includes the skin, hair, and nails (Taylor).

There is a Puritan society in the Scarlett letter which incorporates their organized religion into the political system. Nathaniel Hawthorne wrote The Scarlet Letter and inside of the text he implies a criticism and dislike of organized religion. The text itself critiques the style of organized religion by describing the people as a group of people with sad-coloured garments" and "grey steeple-crowned hats" (Hawthorne 142). Hawthorne pictures the people of the town, as a simple and dark people. The heathen of the story who divided the code of the town, Hester Prynne, is described as “beautiful from regularity of feature and richness of complexion" (Hawthorne 159). He illustrates how he believes the actions of Hester Prynne might

Skin cancer is a term used to describe cancer in skin tisssues. The skin is made of several layers. Skin cancer is classified according to the layer it develops in. Skin cancer is classified according to the layer it develops in. The epidermes is the skin’s outer layer and is made up squamous cells, basal cells and melanocytes

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

Skin cancer is rather common and often does not metastasize. Skin cancer is known to be caused by UV radiation exposure. As such, skin cancer is most often found in skin commonly exposed to the sun like the face, neck, and arms. These more common types of skin cancer are Basal Cell Carcinoma, Squamous Cell Carcinoma, or Melanoma. There is a rarer, more aggressive form of skin cancer called Merkel Cell Carcinoma (MCC). Unlike other skin cancers, this cancer is known to regularly metastasize which results in less successful treatment if not caught early (BOOKLET). Both the layer and types of cells that are abnormal classify types of skin cancer. Merkel Cell Carcinoma is a disease of uncontrolled growth of Merkel skin cells. Merkel cells are found in the basal layer of the epidermis, which is the top layer of the skin. Merkel cells are located close to nerve endings and are thought to function as a neuroendocrine cell.

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 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)
