“Charles” by Shirley Jackson is a short story about her daily life with her kindergartner Laurie. Laurie, an older brother of one infant, started kindergarten as quite a mischievous little boy. Following his daily routine in the 1950’s, he attends his local kindergarten and returns home following the completion of the school day. Unexpectedly, he did not transition as smoothly into kindergarten as they would hope he had. In addition, there was a so-called juvenile delinquent creating a disturbance among the classroom. One can only infer that his reasons to misbehave were to obtain attention. To redeem himself from his sinful acts, he became the teacher’s helper.

The skin is one of the most important organs of the whole human body. It is the largest organ in the human body and contains various functions including protecting the body from injury and preventing fluids from leaving or entering the body (Boer et al. 2016). In animals, the skin has various functions as well. The skin aids with locomotion in bats and aquatic mammals, help camouflage the body in chameleons, helps with finding mates for deer with their white tail, and serves for many other purposes. The skin is composed of three layers in the human body: the epidermis, dermis, and subcutaneous layer. Melanin is produced from melanocytes in the epidermis of the skin. Melanin is important for protection from ultra-violet (UV) rays.

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.

While the original goal of mandatory minimums was to target drug traffickers, Congress was irrefutably concerned with reducing drug use. Hastily created during the peak of the drug epidemic, the policies demonstrate a complete lack of understanding of drug addiction. Lawmakers misconceived the causes of drug crime and instead created a policy that does not accurately address the root of drug abuse. As a result, drug use, crime, and trafficking remain unaffected, even heightened, by the policy.

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

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 tough, relatively thin outer layer of the skin, or epidermis is made up of five layers of keratinocyte cells. This outer layer of the skin acts as the bodies first natural form of defense by preventing most bacteria, viruses and foreign objects from penetrating the body. Additionally, the epidermis layer of skin works to protect internal organs in the body against trauma. The epidermal layer of skin present on the palms of the hands and the bottom of the feet are much thicker to provide additional protection due to the stratum corneum, the outer keratin layer of the epidermis. Melanocytes can be found in the deepest layer of the epidermis, the basal layer, its primary function is to protect DNA from harmful exposure to ultraviolet radiation from sunlight (Holder, Robinson & Laub, 2011).

The dermis is the inner layer of the skin, and includes: hair follicles, nerves, sweat glands, small

In the epidermis there are 4-5 layers of cell, however, the skin that is most exposed to the sun is thin skin, which has 4 layers, because thick skin is located in the palm of your hands and feet. Sunlight is mostly exposed to outer surface of skin, epidermis, which also makes sense why basal and squamous cells is the most common skin cancer. In lab, we got to look at a 3D skin model, which showed all the layers of the skin. This allowed us to see where the layers of the skin are at and also what layers and structured get effected with

In the majority of the areas, just four layers can be differentiated: the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum (p.119). Another layer is the stratum lucidum which can be found in the thicker part of the skin of the palms and soles (p.119). The epidermis has major protective function such as protecting the underlying wet tissues of water loss in excessive way, and against mechanical injury (p. 119). The epidermis also protects against the effects of dangerous chemical and to keep disease that cause microorganism out of the body (p.119). Melanocyts is a cell of the epidermis that produces melanin, a dark pigment that gives the color to the skin (p.119). Although genetic plays an important part in the skin color, the quantity of melanin interferes on how dark the skin is (p.119). According to Shier, Butler, and Lewis 2009 “melanin absorbs ultraviolet radiation in sunlight, preventing mutations in the DNA of skin cells and other damaging effects.”

Once the keratinocytes migrate up to the skin surface they are gradually shed and are renewed with cells pushed up from below. The furthermost section of the epidermis, the stratum corneum, is rather waterproof. Its function is to prevent most bacteria, viruses and other foreign substances from infiltrating the body. The epidermis also protects the internal organs, muscles, nerves and blood vessels against trauma. The stratum corneum is significantly thicker in areas such as the palms of the hands and soles of the feet as they need more protection. Melanocytes are cells which produce the pigment melanin which are found scattered throughout the basal layer of the epidermis. Melanin is one of the main contributors to the colour of skin however, its primary function is to filter out ultraviolet radiation from the sun. This ultraviolet radiation is damaging for DNA which can lead to skin cancer and many other harmful effects. As well as keratinocyte and melanocyte cells, the epidermis also contains Langerhans cells. These cells help detect foreign substances, defend the body against infection and is also involved in the development of skin allergies. (MacNeal,

Melanin is a pigment that determines the colour of the skin, eyes and hair, playing a role in camouflage, heat regulation and cosmetic variation. It also plays a critical role in photoprotection due to its ability to absorb harmful ultraviolet radiation (UVR). As the skin is the largest organ of the body, it is constantly influenced by external and internal factors thus, melanin is an important defence system that protects the skin against harmful factors (Costin & Hearing, 2007). The process by which melanin is produced and distributed by the epidermal units of the skin is called melanogenesis (Videira, Moura, & Magina, 2013). Extrinsic factors, such as UVR and certain chemical compounds, and intrinsic factors, such as secretions by keratinocytes or fibroblasts, can have an influence on melanogenesis. Predetermined genetic factors, such

One form of skin cancer is melanoma, is the rarest but the most virulent of the skin cancers. It is responsible for 75% of all deaths from cancer. It is “a cancer that arises in the melanocytes, the cells that produce melanin. Melanin is the pigment that gives our skin, hair, and eyes their color and that allows us to tan” (Schofield & Robinson, 2000, p. 1). Melanocytes are located throughout the body, “in the retina of the eye and in the linings of the mouth, nose, anus, rectum, vagina, and spinal cord,” (Schofield & Robinson, 2000, p. 6). However, majority of them are located in the skin. The purpose of these cells are to make melanin to protect our skin cells from the sun’s ultraviolet rays (UV rays). The melanocyte cells are found between the dermis (the second layer of skin) and the epidermis (the outermost layer of skin). Normally every ten cells found within the epidermis and dermis are melanocytes the others are cells called keratinocytes. Melanin is made inside the melanocytes then is transferred along the cells’ long arms (dendrites) to nearby keratinocytes in the epidermis. Melanoma arises when there is an uncontrollable increase in the reproduction of melanocyte cells. Although, skin cancer mostly develops just below the skin’s surface, where an existing mole is located, it can get into the blood vessels and lymphatic

The objective of cosmetic experts is to enhance the appearances of a face by the help of permanent tattooing in place. It is also called as the micro pigmentation procedures. Under this procedure colors are mimic skin to shape the eyebrows and lip color. The Permanent makeup training Seoul is advancing in the field of their cosmetic therapies. While persuading a diploma degree courses are most highlighting aspects for any students. Many makeup artists find out about training in different fields cosmetology.
