2.1. Percutaneous medical devices Percutaneous medical devices are increasingly used in several medical applications and are indispensable in the medical field [1]. Percutaneous devices are defined as foreign bodies crossing the epithelial barrier connecting external systems to the internal structure of the body(fig). Table 1 summarizes the list of percutaneous medical devices. These percutaneous medical devices breach the epithelial barrier in a temporarily or permanent manner; therefore, breaking

or integument system is composed of many different sections and accessories, functions for multiple outlets, and falls at risk of disease everyday. The integument is divided by two main sections, the epidermis and dermis. (Amirlak) The outermost layer of the skin is the epidermis. The epidermis is composed

Abstract How many times have you heard, you look just like your brother or sister? Have you ever wondered why people tell you that you look like your mother and father when they were your age? Many related people appear to have several similar physical traits because they inherit half of their parents’ DNA, the genetic plan. What about fingerprint patterns? Are they inherited traits too? Fingerprints are used to identify Homo sapiens because each person has a unique fingerprint detail but has similar

II The Skin has numerous functions as it serves as a protective barrier, regulates body temperatures, controls water retention, and secretes sweat and so on. The anatomy of skin can be broken down into three different layers which include; the epidermis, dermis, and the subcutaneous tissue also known as the hypodermis. The purpose of this paper is to explain the relationship between the layers of skin and friction skin

-Skin is composed of 3 layers- the epidermis, dermis, and subcutaneous fat/hypodermis. -In addition to the epidermis, dermis, and subcutaneous fat, the skin also has sebaceous glands and sensory receptors (located in the dermis). -Sensory receptors are either interoceptors (detect stimuli in the body) or exteroceptors (detect stimuli outside the body). -These receptors can be further categorized into chemoreceptors (react with chemicals), photoreceptors (react with light energy), mechanoreceptors

The Epithelial Cell In the human body, there is such thing that exists that is part of almost every system-the epithelial cell. The epithelial cell is part of many systems, but is most commonly found in the integumentary system. This cell has is part of many like how the cell is bound together as sheets of tissue called epithelia. Lots of people experience malfunctions with this cell like acne, warts, and others. This cells is a part of many body systems, it is part of structures, and has many malfunctions

Diagnostic Considerations: Any inflammatory process that involves the skin, such as contact dermatitis, can leave areas of hypopigmentation upon healing. Examine for the following potential signs of atopic dermatitis: Eczema in the popliteal or antecubital fossa , Nipple eczema, Cheilitis , Dennie-Morgan infraorbital fold , Anterior neck folds, Wool intolerance, White dermographism and Infra-auricular fissuring. This may occur in other disorders as well, including fungal diseases (eg, tinea

compressed into the smaller surface area. To assess such a question, the following statement was made: Young and old leaves of the same plant species do not have different stomatal densities. Leaves contain, in their outermost layer of cells, called the epidermis, small pores which are regulated by two guard cells, that help balance the gas exchange and water loss within the plant. These small pores along with the guard cells are called the Stomata: they open and close due to environmental signals, allowing

Your Skin: A Very Adaptable Organ The skin is the largest organ in the body and is composed of three main layers; the epidermis, the dermis and the subcutaneous layer. (Hse.gov.uk, 2015) The top layer of the skin is the epidermis and is largely made of keratinocytes, or epidermal cells. Under the epidermis is the dermis, which is composed mainly of collagen but also contains hair follicles, apocrine glands and eccrine glands. Many blood vessels, lymphatics and nerves also pass through the dermis

Thompson, & Miller, 1992). The dermis is therefore responsible for regulating body temperature and blood pressure (Kemble & Lamb, 1984). The blood from the dermis is responsible for the nourishment of newly generated cells in the inner layer of the epidermis (MacDonald, 2009). The function of the dermal connective tissue is to provide structural support for the outer layer of the skin (Martini, Ober, & Bartholomew, 1999). Sensory nerve fibres can also be found in the dermis, which respond to touch, pain
