The integumentary system has five main functions. The five main functions of the integumentary system are protection, regulation, sensation, absorption, and secretion. It consists of the hair, nails, skin, sebaceous and sweat glands. The largest organ of the entire body is the skin. The skin consists of three different layers. The epidermis, the dermis, and the subcutaneous layer, these are the three layers of the skin. There is a layer that is deeper than the skin and contains body fat, that layer is called the hypodermis. Sweat glands are also called sudoriferous glands. One of the functions of the skin is to maintain homeostasis. Synthesis of vitamin D, excretion of urea, excretion of salts and water are a few things that the skin is also capable of. The top layer of the skin is called the epidermis. The epidermis contains five different layers. These layers are the stratum corneum, the stratum lucidum, the stratum spinosum, and the stratum basale. In the epidermis there are four different cell types. The keratinocytes which produce keratin, the merkel cells that are sensitive to touch, the langerhans cells which is a dendritic type off cell, and the melanocytes which produce melanin.
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...

...may have the same symptoms. The symptoms are red bumps that may bleed if the sores are picked over.
Another condition associated with the integumentary system is impetigo. This skin condition is mostly seen in children. This condition of the skin is very easy to diagnose and is usually done with the doctor just looking at the patients affected area. The doctor may take a piece of the sore and send it to a lab to get a clearer diagnosis of impetigo.. impetigo ia contagious and can be spread by sharing towels and close contact. It also can be spread by scratching. The symptoms of impetigo are small red bumps around the mouth and nose area. Blisters and crusty sores are also symptoms. The treatment for impetigo is antibiotics. In a mild case of impetigo antibiotic ointment or cream is prescribed. In severe cases the doctor prescribes antibiotic pills to the patient.
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
As a result, she wanted to provide a better and memorable childhood for her children by educating them in a better way. For instance, by showing and transmit them love and at the same time doing so with other people and animals. That animals are not just an object or an insignificant life but to treat them as part of the family. She wanted to show them those principles by not having a repetitive cycle about her own experiences as a child.

These recurrent nodules and abscesses not only cause pain, but self-consciousness, social isolation and even depression. Other less common complications include severe infections, restricted movement caused by a buildup of fibrosis and a type of skin cancer called squamous cell carcinoma.
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)

Cellulitis is an acute spreading bacterial infection of the connective tissue, dermis and subcutaneous layers of the skin (ProQuest 07/2012 pg.5). Characterized by redness, swelling, warmth, tight/shiny skin and pain. It is sometimes accompanied by fever, swollen lymph nodes, chills and fatigue. Cellulitis first appears on pink-to-red minimally inflamed skin. The area of infection rapidly becomes deeper red and increases in size as the infection spreads. Occasionally, red streaks may radiate outward from cellulitis. Blisters or pus filled bumps may also be present (skinsight 12/2012 pg.5). The main culprit is the bacteria Streptococcus and Staphylococcus which can enter through a break in the skin.
The four tissue layers are the mucosa, submucosa, muscularis externa, and the serosa. The mucosa is the inner most layer which also composes of its own; the epithelial, lamina propia, and muscularis mucosa. The mucosa secretes hormones, digestive enzymes and also mucus as well. The submucosa is composed of areolar connective tissue, which contains a rich blood supply, nerve fibers and lymphatic vessels and follicles. The muscularis external is the layer that is responsible for the function of segmentation and peristalsis. It contains an inner circular layer and also an outer longitudinal layer both of smooth muscle cells. The serosa is the layer that is the outermost. It is also called the visceral peritoneum and it is areolar connective tissue that is covered with mesothelium.
The skin is the largest organ in the body, covering the bones and internal organs, protecting them from injuries, it serves as a barrier to germs, and bacteria and helps to prevent fluid loss. The skin helps to control the body’s temperature and also aids in removing certain body wastes, therefore making it a vital organ just as any other organ such as the heart or brain.
The integumentary system is composed of the skin and the structures related to the skin, which include the hair, the finger nails, the sensory receptors and the glands (Shier, Butler, & Lewis, 2009). This system has an important function since it provides protection to the body, helps to maintain body temperature, and contains sensory receptors (p.117). The skin has essential function such as regulating homeostasis and body temperature, also delaying the loss of water from deeper tissues, storing sensory receptor, synthesizing biomechanical, and discharging waste from the body (p.117). The skin has two layers: the epidermis (outer layer) and the dermis (inner layer) (p.117). There is also a subcutaneous layer or hypodermis (p.117). According to Shier, Butler, and Lewis 2009 “as its name indicates, this layer is beneath the skin and not a true layer of the skin” (p.117). This layer has the blood vessels that supply the skin (p.117).
Integumentary system, It is the largest organ in the human body. This applies to exterior surface; function: It operates as insulation. Senses pain and preserve the body tissues against (pathogens) bacteria attack and control loss of fluid.
The musculoskeletal system is comprised of bones, joints, cartilage, tendons, ligaments, fascia and muscles. Together these body parts work to establish a framework that is the musculoskeletal system. This framework is what gives the body its shape, form, and figure. It stabilizes the body as well as supplies the structural support. The musculoskeletal body features not only provide a framework for your body but allows your ability to create movement. These movements are monitored by the musculoskeletal components which then determine your degree of flexibility. Overall the amount of energy your body uses comes almost entirely from these musculoskeletal functions. Which makes sense because it
While sitting around your house, watching television, you notice that you have been scratching your arm and in between your fingers for a little while. After taking a closer look you notice something that you assume is a rash and just ignore it. The next day however you notice that the rash has spread and that you think you see burrows in your skin. Then it hits you, the weekend that you spent away on vacation in that not so expensive hotel to save a couple of dollars has now cost you more money in the long run. You must go see your doctor to be treated for scabies!
The symptoms of psoriasis differ from type to type, although inflamed, scaly lesions are present in all five types. The most common form of the disease, plaque psoriasis, is identified by small bumps that begin to grow and become scaly. These lesions flake easily, but removing these patches can cause the tender skin below to bleed. In the Guttate type, small, individual, red drops form. This type does not have as much scaling as plaque psoriasis. The drops usually clear up on their own, but may also reappear as a different form of psoriasis, usually plaque. Inverse psoriasis usually occurs in places where the skin folds, such as the genitals, breasts, armpits or the backs of knees. This type will appear red, yet it will be smooth and dry. Also, no scaling will occur. Pustular psoriasis is a type that's significantly more rare. It is also more painful. In this type, blisters filled with non-infectious pus appear within a few hours and then dry up and peel within another two days. Severe medical risks exist for those who have this particular form of psoriasis, due to its side effects; exhaustion, anemia, weight loss, fever, chills, rapid pulse rate, severe itching and muscle weakness. Even less common than pustular psoriasis is erythrodermic psoriasis. This type is...
The skin has 3 main function. It has to regulate body temperature, remove waste (perspiration), and protect. The skin is made up of 3 layers. The epidermis is the outer thinner layer of the skin that is made up of dead and living cells. The dermis is the thicker middle layer of the skin that contains blood vessels and nerves. Sweat glands are found in the dermis, they secrete perspiration through ducts to pores on the skin’s surface. To avoid problems like warts, boils, moles, acne, and sunburn you can wash your body daily, wear sunscreen that is 15 or higher, and check your body often...
