Skin And The Human Body

Skin cancer is a condition where cancerous cells form in the epidermis. The epidermis is the first layer of your skin. Melanoma can be on any part of the body (Egan 23-24). This form of skin cancer can be treated in the early stages of formation. Basal cell cancer is one of the most common types of skin cancer, this cancer may also happen on the sun exposed skin and on the face (Egan 10).Squamous cells are the second most common form of skin cancer. Squamous cells form on sun exposed skin (Egan 11). For example, it could potentially form on the shoulders, neck, or hands (Egan 10-11). Each stage of skin cancer may vary depending on the person.

Although there are several types of skin cancer, the most aggressive form is melanoma. This cancer of the skin involves mass replication of the pigment producing melanocyte cells, which are located in the epidermis, below the basal layer. There are several factors involved with the onset of melanoma including, exposure to ultraviolet rays, genetic predisposition, numerous nevi (moles), immunosuppression, and environmental exposure to carcinogens.

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

There are different types of skin cell cancer. Bell cell carcinoma (BCC) involves slow growing, malignant epidermal tumors that develop from hair follicles. These tumor infiltrate surrounding tissues and invasively destroy vulnerable areas, such as skin that is chronically exposed to the sun. The sun-exposed areas of the neck and head are at highest risk, where small white or translucent lesions will likely appear. Squamous cell carcinoma is a cancer that is caused by too much UV exposure or from excessive use of sunbeds. It is technically caused by uncontrolled growth of abnormal squamous cells and medically treated through safe dermatology

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 outermost layer of the skin is the epidermis and is made up of stratified squamous epithelium. The epidermis does not contain any blood vessels and is vastly made up of keratinocytes. These cells secrete a protein called keratin which contributes to the tough feeling of skin and its water resistance. The epidermis also contains melanocytes that are responsible for skin pigmentation and Langerhans cells that work as a part of the immune system to provide an immediate defense if a foreign substance were to come in contact with the skin. There are also Merkel cells in the epidermis that are responsible for sensations such as light touch and slight pressure (Patton & Thibodeau, 2009). Aside from these features, the epidermis is also made up of five distinct layers called strata.

The thin layer of tissue forming the natural outer covering of the body of a person or animal. The skin is made up of three layers. The outermost layers of the skin is the epidermis,made up of tough keratin which has several layers that constantly grow outward. The second layer is called the stratum corneum,from the covering of dead skin. Its thickness varies due to being ten times thicker on the soles of the feet than around the eyes.The third layer is called the epidermis, it defends Langerhans cells, which alerts the body's immune system for viruses and infectious agents. The skin achieves strength and pliability by being composed of numbers of layers oriented so that each complements the others structurally and functionally.

The skin protects against heat, sunlight, injury, and infection, it also helps control body temperature and stores water and fat. Skin cancer is the most common type of cancer. It usually forms in skin that has been exposed to sunlight, but can occur anywhere on the body. Skin has several layers. Skin cancer begins in the epidermis (outer layer), which is made up of squamous cells, basal cells, and melanocytes. There are several different types of skin cancer. Squamous cell and basal cell skin cancers are sometimes called nonmelanoma skin cancers. Nonmelanoma skin cancer usually responds to treatment and rarely spreads to other parts of the body. Melanoma is more aggressive than most other types of skin cancer. If it isn’t diagnosed early,

Skin cancer is a rather common genetic disorder that occurs today within the United States. On average, nearly forty to fifty percent of Americans will experience skin cancer by the time they reach sixty-five years of age. Skin cancer comes in many different forms, yet the most common and prevalent are as follows. Basal Cell Carcinoma can be observed as uncontrolled, abnormal growths on the skin. They arise from the basal cells of the skin (found in the top layer of skin) and tend to look like lesions, open sores, scars, or bumps. BCCs (Basal Cell Carcinoma) are usually caused by intense exposure to sunlight and affects nearly four million people in the US on a yearly basis. However, this form of skin cancer usually doesn’t move from the origin of the tumor and very rarely becomes a life-threatening condition.

Skin Cancer is the most common type of cancer. Among the three types of skin cancer, basal cell carcinoma (or BCC) is the most frequently occurring type of skin cancer. BCC is a type of skin cancer that “begins in the basal cells, which are a type of cells within the skin that produce new skin cells as old ones die off” (Skincancer.org). BCCs are abnormal, uncontrollable growths of new skin cells that result in red and pink spots, lesions, and scars.

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 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

Cancer is the second biggest killer in the United States. Anyone can develop cancer, and the older we are, the more likely we are to develop the disease. Out of all the different kinds of cancers skin cancer is the most common human cancer. Approximately 40 to 50 percent of 65 year olds in the United States will develop at least one form of skin cancer. People who live closer to the beach are at a high risk of developing skin cancer due to the higher ultraviolet radiation levels at this location.

The skin is the largest organ of the body; although, it is only a few millimeters thick. It helps to protect the body from chemicals, ultraviolent light, disease, and physical damage. The epidermis is the outer layer of skin that covers almost the entire body. This layer lies above, and protects the dermis, which is the inner layer of the skin. The epidermis does not contain blood or blood vessels; however, the dermis does. There

Epidermis : this is the layer of skin that we can see, it has the thickest layer which can be found on the soles of the feet and palms of the hands, thinnest layer on the eyelids and nipples. The cells on surface are constantly shedding (the dead cells) this is called Desquamation.
