Recommended: Psoriasis lesion
Psoriasis is a disease of the integumentary system that results in a skin rash, and also sometimes the rash involves the joints and nails. The epithelial cells of the skin are hyperproliferative, and result in a thickening of the uppermost layer of skin called the epidermis. Psoriasis is chronic and so far, cannot be cured. Treatment options are available in the sense that the visual results, the lesions of the skin, can be treated but often times reoccur when the treatment is stopped. Because of of the neutrophils, dendritic cells, macrophages, other cells involved in the disease, we are led to a debate. Is psoriasis caused by the skin’s T cells, or just the skin? The first hypothesis was that psoriasis is a disorder of the epidermis due
To begin we will look at the integumentary system and its entire multitude of functions. The main components of the integumentary system are the skin, hair, nails, glands and nerves. For the purpose of this paper we will focus mainly on the levels of the skin and their functions. While the integumentary

The immune system is made up of a network of cells, tissues, and organs that work together to protect the body, and it defends the body from “foreign invaders.” Immunity can be divided in two three different defenses, and these are defined as first, second and third lines of defense. The first line of defense for the immune system is the primary defense against pathogens entering the body from the surface in order to prevent the start of disease and infection. Some examples of the first line of defense is the skin, protecting the external boundaries of the body, and the mucous membranes, protecting the internal boundaries of the body. Although the skin and mucous membranes work on the internal and external boundaries, they both release chemicals
Hair is considered one of the components of the integumentary system, along with the skin, nails, glands and nerves. Mammalian hair has many functions including protection from environmental factors and the ability to disperse sweat gland products such as pheromones. Almost every part of the human body is covered by hair except for the palms, hands and bottoms of the feet. On average, every person has about five million hairs; each of these hairs is born from a follicle or tiny tube-like structure that grows into the dermis layer of the skin. Oftentimes this follicle even reaches the subcutaneous layer, which is made of fat and connective tissue. (UXL Complete Health Research, 2001)
The autoimmune process that causes pathogenicity is the formation and activation of antibodies targeting the keratinocyte desmosomal cadherins or for simplicity desmosomes. The latter is responsible for the adherence of keratinocytes, and when it is targeted by these antibodies the desmosomes lose their ability to maintain keratinocytes together and the cells become detached. “Ultrastructural studies of pemphigus lesions have suggested that dissolution of desmosomes may result in the formation of blisters. This is a phenomenon known as acantholysis.” (Loannides, Lazaridou, Rigopolous, 2008)
More specifically, atopic eczema refers to a very characteristic itchy skin rash, which usually starts in infancy or childhood. It starts to affect different parts of the skin at different stages of the person’s development, but at some point usually comprise the skin creases (flexures) of the arms and legs.
What are these red patches of skin on my body that I can’t ever help from scratching? It is eczema, which is defined as a medical condition in which patches of skin become inflamed, with blisters that cause itching and bleeding. Genetics take a role in the possibility of having eczema, after comes the diagnosis, then being prescribed the treatment needed, and lastly their prognosis.
The first known use of dermatology was established in 1819 and only in the 1930’s did its practice become more widely accomplished, known and sought after. (“Dermatology” 2014) Since then it has extensively evolved and changed and been able to provide services for women and men around the world. Originally being a part of the medicine field can now be considered a division of the beauty industry due to availability of services and treatments for aesthetic, pampering purposes, rather than just originally founded for medical issues of resolving skin disorders and diseases. Dermatology being defined as ‘a branch of medicine dealing with the skin, its structure, functions and diseases’ (“Dermatology” 2014) now offers many professions one being a dermatologist, whic...
Atopic dermatitis: This is a chronic type of eczema characterized by itchy and inflamed skin. It is common among individuals with a history of asthma and hay fever.
The integumentary system consists of three layers, which include the epidermis, dermis, and subcutaneous layer. Various tissues, such as hair, nails, sebaceous glands, and sudorferous glands identify the integument as an organ. The layers and tissues protect the organ system against environmental threats, such as heat, sunlight (solar), and infections. However, when skin is damaged by ultraviolet rays, secondary lesions called actinic keratoses (solar keratoses) may develop.
The second layer of the skin is called the dermis and is also known as the middle layer. The dermis is what holds the body together. The dermis has layers to it as well as the epidermis. There are two layers to the dermis, the papillary layer and the reticular layer. The cells of the dermis are fibroblast, macrophages, mast cells, and scattered white blood cells (wbc’s). the dermis is richly supplied with nerve fibers and BV;s. dermal BV’s is also a part of the integumentary system, dermal BV,s have converging and diverging vessels that ar...
The skin is part of the integumentary system; it is the largest organ of the body. The skin helps regulate body temperature, permits the sensations of touch, and protects the body from external infection. (Lewis, Dirksen, Heitkemper, & Bucher, 2014). Overtime mostly with bed bound patients the skin develops injuries due to prolonged pressure on the bony surface of the body and this is called pressure ulcer. A Pressure ulcer is a “localized injury to the skin and/or underlying tissue (usually over a bony prominence) as a result of pressure or pressure in combination with shear and/ or friction.” (Lewis, et al., 2014, p. 184).
Psoriasis is a chronic skin disorder, easily identified by its symptoms of white, scaly skin and red lesions, though not so easily cured or understood. In psoriasis, skin cells mature faster than the body can shed them, causing a buildup. Although there are many theories as to what the cause of such a disease might be – genetics, stress, or other triggers – no one is quite sure why the disease occurs, or what could be a possible way to fully cure it. In this essay we will explore the symptoms, types, and effects of this condition, and also some of the known treatments.
Eczema is one of the many skin diseases that humans can obtain the moment they are born. This disease is when any part of the body’s skin becomes dry, itchy, and red. Eczema is very common on the face, which can be very serious for some individuals. In the article, “What Is Eczema?” it explains how 30 million Americans have some type of eczema on various parts of the body (para7). Most individuals who suffer from any type of this skin disorder, later come to find out that they have had a type of allergy that makes their skin show symptoms of eczema. This specific skin disorder has a higher tendency for women to develop a physiological disorder more than men, because of the restriction of being able to cover up the affected areas with makeup if it’s visible, due to its peeling and itchy skin
