Epidermis Essays

The gross anatomy of human finger nail consists of the following: 1. Nail plate: The nail plate is mainly produced by the matrix which emerges via the proximal nail fold and is held in place by the lateral nail folds. It overlays the nail bed and detaches from the latter at the hyponychium which is the skin under the free edge of the plate. The nail plate has an average thickness of 0.25–0.6 mm. It is hard, yet slightly elastic, translucent, convex and is made up of approximately 25 layers of dead

etc. One major function of the skin is to protect. The skin is the protective covering of the body that prevents the invasion of microorganisms. The skin consists of two layers the epidermis and the dermis. The first layer of the skin is the epidermis which contains stratified squamous epithelium. The epidermis consists of the stratum corneum and the stratum germinativum. The stratum corneum is the outer layer of skin cells that

of two layers; the Epidermis and Dermis (under which lies the subcutaneous or fatty layer). The epidermis is the layer of skin that we can see. It varies in thickness. The thickest layer is on the soles of the feet and the palms of the hands. The thinnest layer is on the eyelids and nipples. The cells on the surface are constantly coming off (shedding) this is known as desquamation. They are also constantly being replaced from below as cells from the basal layer of the epidermis multiply and are pushed

maintenance, blood storage, as well as excretion by means of sweat. The anatomical structure of the skin can be divided into two main parts, the epidermis and dermis. The third part of the epidermis is the hypodermis, it is also known as the superficial fascia, where it is mainly comprised of adipose tissue and is therefore not examined as part of the skin. In the epidermis of the skin, there are specialized cells located in several distinct layers. The main epidermal cells are the keratinocytes and melanocytes

system turns against itself (autoimmune disease) where immune cells attack color-producing cells called melanocytes or cause them to stop functioning, causing color loss of the skin resulting in white patches of skin across the body; affecting the Epidermis. Vitiligo can affect anyone but it is mostly noticed on darker skin tones & would be found common to start at the age of 20+. Vitiligo can start as a small patch of white skin and can continue to spread over any part of the body including eyes, mouth

Introduction: In vertebrates, the skin is made up of two layers: the outer epidermis and inner dermis. The epidermis, being the outermost layer, functions as a protective barrier between the external environment and the internal organs of the body, thereby protecting the internal organs from external stresses such as pathogens, toxins, water loss, chemical and physical stresses, etc.1 A majority of physical stresses that the epidermis experiences are in the form of spring forces, osmotic pressure, tensional

homeostasis and allows the sensation of touch, heat and cold. 1.2. SKIN LAYERS Skin is called as integumentary system of three layers as following: 1. Epidermis 2. Dermis 3. Hypodermis 1.2.1. Epidermis It is the upper layer which provides waterproof barrier and creates color tone because of the presence of melanocytes, which produce melanin pigment. 95% of epidermis is consist of Keratinocytes, which are characterized by cytokeratin

coating layers. One is the epidermis, the next is the dermis, and the last layer is the subcutaneous tissue known as the hypodermis.   A. Epidermis - This outer layer has stratified squamous epithelium to keratinize the skin, and to make it solid and strong. The epidermis does not receive or give blood, but it has up to five strata. They are the stratum basale, spinosum granulosum, lucidum, and corneum. Multiple epidermises deliver keratin and the protein allows the epidermis to become a muscular protective

The skin is the largest organ of the body, covering about 1.7 m2 and comprising approximately 10% of the total body mass of an average human being. The primary function of the skin is to provide a barrier between the body and the external environment. This barrier protects against a range of noxious assaults like UV radiation, mechanical, chemical and biological insults like allergens and microorganisms. Its physical strength and elasticity provide optimal mechanical support; semi-permeability to

Have you ever seen someone with an unusual hair color? Was it a neon, or a vibrant color? Did you know that people not only can have natural hair colors, but other colors like neon? It has gotten to the point of glowing neon hair. It’s all true. Using melanins and developers, a hairstylist can dye your hair any color of your dreams. First, what makes our hair dye, or gives our hair color? Melanins. There are two types of Melanins, Eumelanins and Pheomelanin. According to Hairscience “The cells

are the cutaneous membrane, or the accessory structures. The epidermis, dermis, or superficial epithelium are two components that are

A) Skin histology and terminology : The skin consists of 2 main layers ,the epidermis and the dermis. The dermis and the epidermis are derived from a different embryologic tissue type. The subcutaneous tissue resides immediately beneath the two primary layers of skin. The outer layer of skin (the epidermis) consists of stratified squamous keratinizing epithelium and is derived from ectoderm (Fig. 1). The epidermis contains no blood vessel sand is nourished entirely from tissue fluid emanating

affected in are her elbows, her knees, and her back. Although there are five layers of the epidermis, only four layers are affected in Stephanie. I have concluded this due to the fact that her skin is extremely thin due to her condition, which means that one specific layer, known as the stratum lucidum will be absent. The layer stratum lucidum is only present in thick skin. The four layers of Stephanie’s epidermis that are affected are known as the stratum basale, stratum spinosum, stratum granulosum

is expanded when he explains what makes the epidermis. In Mr. Anderson’s video, he explains that there are three layers of skin which are the epidermis, dermis, and the hypodermis which is also known as subcutaneous. Then it gets to the part where it’s a dream within a dream except this time it’s being replaced with a layer within a layer. The first layer of skin is the epidermis which can have, at most, five stratums (layers) of skin in the epidermis. The layer that can be seen is the stratum corneum

and protecting the body. It consists of two layers: the outer epidermis and the inner epidermis. Beneath these layer is the adipose tissue, which contains fat-rich cells. PROTECTION:The outermost layers of the skin are dead cells, this protects the living cells below from Infection, Mechanical, Dehydration. The epidermis protects the body from damage and acts as barrier to prevent the loss of water and the entry of pathogens.The epidermis is the outer layer of the skin. Cells in the Malpighian layer

constant precipitation in the rainforest environments, tropical plants are constantly absorbing water in through their roots. And as said already, water will evaporate out of the plant through the pores of the leaves, specifically the stomata in the epidermis, through the process of transpiration. If there was not constant precipitation in rainforest ecosystems, tropical plants would not be able to survive, and would dry out, due to the lack of water combined with constant transpiration of water out of

pandemic Mumps - a contagious disorder with a view to reason an inflammation of the salivary glands Osteomyelitis - a continual and severe bone illness Rubella (German measles) - a contagious illness which is characterised with the aid of a rash on the epidermis Septic or infectious arthritis - an infection of a joint triggered by way of a bacterial infection Syphilis - an sexually transmitted illness brought on by using the micro organism Treponema Pallidum Joint anguish reasons Degenerative, inflammatory

also regulated to a certain extent by the skin. The skin is made up of three layers and all the layers have a key role in acting as the defense. The outermost layer which is the epidermis is an actively regenerating layer. This layer keeps on growing and differentiating to maintain the pH and moisture content. The epidermis does not work alone in keeping the skin healthy. The dermis which is the second layer is more active and hosts capillaries, blood vessels, elastin and also fibroblasts. Dermis also

the unknown microorganism was motile and produced Indole. Identification: Staphylococcus epidermis Justification: Staphylococcus epidermis is glucose fermenter. The unknown organism fermented glucose in the Phenol Red Glucose broth. Staphylococcus epidermis produces the enzyme catalase. In the PEA Agar, a catalase test was performed which showed that the organism produced catalase. Staphylococcus epidermis is not a mannitol fermenter. Mannitol fermenting organisms grow on the Mannitol Salt Agar

Introduction As we already know UV (aka sunlight and artificial UV lighting) can cause forms of skin cancers. It seems to be common sense now days but we really don’t know how or why specifically and we also don’t really know what preventative measures actually work. As we grow up every day we expose ourselves to sunlight but unless we are going out to the beach or pool, we don’t take preventative measures to keep our skin safe from radiation and some are even attempting to do the complete opposite
