Dermis

Skin A third-degree skin burn extends through the entire epidermis, dermis and hypodermis, but leaves the underlying muscle and bone tissue in a functional state. Skin is made up of three layers: the epidermis, dermis and hypodermis. The epidermis is ectodermal in origin. It is relatively void of ECM except for the basal membrane and has a distinctive keratinized layer produced by keratinocytes. Other artifacts of the epidermis include melanocytes, hair follicles, sebaceous glands, and sweat…

It is made up of two layers; an outer layer known as epidermis and layer below called dermis. The epidermis is considered as more protective layer as it’s thicker, whilst dermis contains collagen and fibre, also upholding a network of blood vessels, hair roots, glands and extensions of the inner nervous system. In addition, on the outer layer there’s an outermost covering named stratum…

Tissue Repair in Minor Wounds The skin is the biggest protector of our bodies and its organs. It is made up of two primary layers, the epidermis and the dermis. The epidermis is the outer layer of the skin and is a membranous epithelial tissue. The dermis is the inner and thicker layer of the skin and is a fibrous connective tissue that provides strength to the skin (lecture supplement, ch.6). When injury or damage occurs to the skin, it goes through 4 different phases to repair itself. The…

In an ideal scenario, the cure for epidermolysis bullosa should be able to replace the defective genes responsible. This should in turn restore proper protein function, so that the structural integrity of the skin can be restored. Ideally, the treatment should have cell, protein and gene therapy. Due to the fact that this condition is genetic, there is no way of preventing it but there are a few things one can do to be alert and informed of the situation. As early as 8 or 10 weeks of pregnancy,…

most dangerous type of radiation, but does not penetrate the earth’s ozone layer unlike ultraviolet A and B (Medicinenet, 2013). Ultraviolet A stimulates melanin pigmentation, as it is able to reach deep into the dermis. Ultraviolet B is mainly absorbed by the epidermis and upper dermis, and is also responsible for pre-vitamin D3 production in the skin as well as stimulating the production of melanin like ultraviolet A. With continuous exposure to ultraviolet radiation, there is a higher chance…

wrinkle develop around their eyes and mouth where fat is loss the dermis become thinner, and the skin may become transparent and lose its elasticity, its mostly can be found in the older patient. The integument (of skin provides several important functions, namely protection from external environmental influences, thermoregulation, electrolyte balance and sensation – pain, touch, heat and cold. The skin comprises three major layers – the dermis, the epidermis and the subcutaneous fatty layer…

treatments are used. Also the advantages and the disadvantages of each treatment. Within the beauty industry today the trends are changing and they are always introducing and improving new treatments and products that will help the epidermis and the dermis of the skin. According to wedMD when the skin starts to age it goes through…

function? Connected to hair follicles; located in the dermis. Most secrete directly into follicles but some directly onto the skin. Their gland shape differs depending on location. Function is to secrete oil. 16. Describe the structure of hair and list some functions of hair. Shaft consists of the medulla - inner layer, air spaces; cortex - middle layer, pigments; cuticle - outermost layer, hard keratin. Root- similar to shaft, but within dermis. Follicle - surrounds root. Sheath -…

sudoriferous glands (apocrine sweat glands) located in the dermis, produce the sweat that eventually ends up on my hands. Dermal papillae also assist me in gripping the wall with more ease. Keratinocytes which are found in the dermis are involved in protection. Sometimes while climbing the wall, I develop calluses which are caused by friction and come from keratinocytes. Many times while climbing the wall I start to perspire. The dermis contains apocrine glands; whose primary function is…

Introduction The infection at the wound site is a severe kind of problem and it delays regeneration of epidermis and dermis in the wound and slows wound closure. Due to the secretion of microbial enzymes by wound pathogens, a variety of extracellular matrix proteins were degraded. Synthetic antimicrobial therapy used in the wound management and eradication of pathogens. However, it has many shortcomings such as anti-microbial resistance, cyto-toxicity against host tissue and absence of…
