Skin anatomy

The main cause of Skin Cancer is exposure to the sun. Caucasians are more at risk for skin cancer because people with Darker Skin are more evolved to black out the sun. The age that Skin cancer typically occurs is after 50. The incidence of skin cancer is greater in older individuals. The amount of light reaches the North and South Poles in a predictable manner. The map shows all one color near the poles. The latitude that receives the greatest amount of UV light is the equator. Based

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

The five layers of skin are stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. The stratum basale consists of basal cells. The dermal papillae, which increases the strength between the epidermis and dermis, are found there. All keratinocytes are produced here, as

triangular s-iridophores, hence the name, were found to be in the superficial part of the chameleons’ skin; male chameleons showed to possess a more developed layer of this crystal, whereas female and juvenile chameleons possessed an underdeveloped form of these crystals. The more asymmetric rectangular d-iridophores were found to be located in the deeper part of all female, male, and juvenile chameleons’ skin.

these structures however, the main component of the integumentary system is the skin. Consisting of three layers; epidermis, dermis and hypodermis, the skin plays key functional roles in the control of temperature within the body, production of essential vitamins, housing of sensory receptors, secretion of waste products and protection of the body (Kerr, 2010). The epidermis is the most superficial layer of the skin, composed of keratinized stratified squamous epithelium, providing a waterproofed

System: Anatomy and Physiology with a related disorder The integumentary system is an organ that is made of the skin, nails, hair, and the exocrine glands. The skin is the largest organ in the human body. The skin covers the outer body forming a protective barrier from chemicals, disease, UV light, and physical damage. Hair and nails both develop from the skin to protects us from environmental damages. The integumentary has four main types of glands that excrete sweat, oil, wax, and milk. (Skin) The

Anatomy Quiz #2 Chrisheena Wills 1. The layers of the epidermis from deep to most superficial are the stratum basale, stratum spinosum, stratum grandulosum, stratum lacidum, and the stratum corneum. Each of these layers are unique due to the type of cells located in them which they are named after. They all together make up the epidermis, an avascular, superficial, and made up of epithelial cells. a. The stratum basale is the basal layer of the epidermis. It is the basement layer of the epidermis

how the does the skin act as a barrier The skin is cleverly designed to perform in helping the skin acting as a physical, chemical and physical barrier for the body. The physical barrier acts as a protective cover to protect us from the environment i.e. pathogens, physical abrasions and radiation from the sun. Yet it is known to be one of the largest organs in the body in weight and in surface area. In adults, the skin makes up 16% of body weight and the skin covers an area of about 2 square meters

Therefore, although they will feel warmer superficially, body temperature will decrease. They should wear their coats. 10. A hypodermic needle is used to introduce drugs into the loose connective tissue of the hypodermis. Beginning on the surface of the skin in the region of the thigh, list, in order, the layers of the tissue the needle would penetrate to reach the hypodermis.

all directions in the dermis [90]. These fibres are scattered among the collagen bundles and become thicker in the deeper layers of the dermis [90]. Elastic fibres, as their name indicates, are extremely elastic and help in the elastic recoil of the skin and that is the reason why they are more abundant in the dermis of the face, scalp and the extensible organs, such as tendons and arteries [91, 92]. 2.2.2.3 Extrafibrillar matrix The extrafibrillar matrix includes a ground substance (glycosaminoglycans)
