Dermis

and is based on the presence of typical lesions in a characteristic distribution, with recurrence (one accepted criterion is two recurrences over a period of 6 months)[1]. Choice “A” is not the best answer. Cellulitis is an infection involving the dermis and subcutaneous fat. Typically, there is an area of diffuse redness and swelling that develops over a couple of days. The borders of the area of redness in cellulitis are generally not sharp.…

this specific function is no longer preformed adequately. Therefore it is vital that the skin barrier is restored as soon as possible. A cutaneous wound is defined as a break in the epidermis of the skin; however the disruption could extend to the dermis, subcutaneous fat, or even further down into the muscle or even the bone. Cutaneous wounds can be clinically categorised into acute wounds or chronic wounds depending on their time frame of healing. Wounds that repair themselves and that proceed…

haphazard arrangement. • The barrier function of the epidermis is disrupted in the first 24 hours causing the skin to be drier than usual. • However, after 7 days the skin is more hydrated than before. Effects of Microdermabrasion on the Dermis • The thickness of the dermis is increased • The number of collagen fibres are increased and they are thicker, more tightly packed, and more consistently organised • The number of elastic fibres is increased and they are oriented vertically instead of…

The integumentary system is one of the largest systems in the body. This is a protective barrier to all the organs inside and if this system is damaged in any way we expose ourselves to any potential infections. According to The American Burn Association, they state that about 450,000 patients receive hospital and emergency room treatment for burns each year and a burn injury occurs about every 30 minutes. More than 3 million US burn cases occurs per year ("Burn Statistics | Burn Injury Guide").…

Skin is the body’s largest organ; it’s all over us and yet we fail to appreciate the many tasks it must do to keep us safe and disease-free. But our skin is more special and more complex than one thinks. Made up of the epidermis and dermis, our skin can resist and repair cuts and burns and many other traumas. Our skin, however, is not invincible and can sometimes fall susceptible to many different diseases and cancers, like melanoma. Melanoma Per Adam Riker, one of the authors of The…

action Skin is a multilayered organ with the ability to protect the organ¬ism against external aggressions. The skin consists of three main layers including epidermis, dermis and subcutis that are responsible for its high turnover capacity in repairing different injuries. Similar to other tissues, the stem cells existed in skin tissue play an important role in regulating the balance between cell loss and cell division [22, 23]. siRNA therapeutics are potent alternative for skin regeneration due…

Leprosy is also known as Hansen's disease. It is a curable infectious disease that causes skin lesions and nerve damage. Leprosy is caused by Mycobacterium leprae. It affects the dermis, nerves, mucous membrane in the airway, and the eyes (WHO). Anyone at any age is able to have this disease. There are at least three million people who are living with some kind of disability from leprosy. Leprosy used to be most common in Europe until it slowly went away. In the past when leprosy was more common…

of noxious substances and the entry of pathogens, as well as preventing excessive fluid loss from the body. This is the role of the upper layer of the skin, the epidermis, and in particular the stratum corneum. The epidermis is situated above the dermis and is composed of several discrete layers of cells known as keratinocytes Keratinocytes are formed in the lower level of the epidermis, known as the stratum basale, and gradually migrate to the upper layers of the epidermis. During migration…

cancer in the course of their lifetime. A study showed that from 1970 to 2009, melanoma among women age 18-39 increased 800%. The use of tanning beds, bulbs, and other devices attributed to this. The skin is formed of two layers, the epidermis and dermis. The epidermis is made of squamous cells, basal cells, and melanocytes scattered throughout the basal cells. Melanocytes are located in the deepest part of the epidermis and produce the pigments of our skin. Exposing our skin to UV radiation…

Skin considers as the largest body organ. It protects us against the infection, at the same time it is the home to huge numbers of microorganisms. Our skin was sterile only once in our life when we were in the womb, they start colonization of a newborn baby's skin usually occurs during vaginal delivery through the birth canal after birth until death. such as bacteria, fungi and virus. Generally they are non-pathogenic, many are harmless and some are actually very helpful. The number of the…
