Epidermis

Second degree burns are a partial thickness burn that affect the epidermis and the dermis. It is not as serious as a third degree burn but is just as bad. It causes pain, swelling and blistering. The skin appears red, white or splotchy. This type of burn usually is caused by scald injuries, flames, or coming into contact with a hot object. When a second degree burn occurs it affects the inner parts of the skin which result in a red blistering appearance. Burns like this cause severe pain and…

1.1 Background Our skin comprised of two main parts – epidermis and dermis. Epidermis is the superficial and thinner portion which serves to protect the skin and underlying tissues from abrasions, heat, microbes and chemicals. The deeper and thicker connective tissue portion called as dermis hosts several accessory structures of the skin like hair follicles, oil (sebaceous) glands and sweat (sudoriferous) glands. Sebaceous glands secrete greasy substances called sebum that will moistens the…

bacteria. Archaea can be found on human tissue or epidermis, but however, their affluence is unknown and rarely studied. The number of microorganisms on the human epidermis is dependent on a variety of things. For example, the location, presence of moisture, age, sex, immune system and living conditions play an important role in the composition of the microbial communities. Only a few studies have mentioned the detection of archaea on human epidermis with archaea’s role in human skin health and…

Foundation is a colored makeup that comes in both liquid and powder forms. Foundation is used to visually even out skin discolorations, cover flaws, lessen the look of pores, level out skin texture, disguise blemishes and offer a base for other types of makeup. Being a versatile makeup, foundation can be applied in different colors, and styles. For example, foundation can be applied thinly or densely over the skin depending on the coverage needed or it can be selected based on the…

Layers of Epidermis: 1. Stratum basale: The stratum basale or stratum germinativum is a continuous layer which gives rise to keratinocytes. It is usually described as one cell thick .this is the base or bottom made of living cuboidal keratinocytes that undergo cell division (mitosis ) they also have melanocytes that make melanin( dark pigment ). 2. Stratum Spinosum: the stratum spinosum or prickle cell layer is so called because the cells are given a spiny appearance by the numerous desmosomes…

What are sudoriferous glands, and where are they located? They are sweat glands and they are located throughout the body. 11. What is sweat composed of and what are two functions of sweat? Water, salts, urea, uric acid, amino acids, ammonia, sugar, lactic acid, ascorbic acid, and pheromones. Two functions are to regulate body temperature and rid body of waste. 12. Name two types of sweat glands and differentiate between the two. Eccrine and Apocrine sweat glands. The apocrine…

The largest human organ is the human skin, which covers a humans outer being. The general shape of the human skin is much like elastic flat bread stretched to fit an entire skeleton. The human skin resides in the outer realm of the human body like nails. The skin functions as a protection from the elements such as microbes, helps regulate body temperature. Without the skin and nerves could not feel sensations such as heat and cold. Why is touching important? According to Tracy Connor, touching…

varies from 0.5mm thick on the eyelids to 4.0mm thick on the heels.. Structurally, the skin consists of two layers which differ in function, histological appearance and their embryological origin. The outer layer or epidermis is formed by epithelium and is of ectodermal origin. The underlying thicker layer, the dermis, consists of connective tissue and develops from the mesoderm. Beneath the two layers, there is a subcutaneous layer of loose connective tissue,…

The skin is made up of three layers the epidermis, dermis, and the hypodermis. The epidermis contains epithelial tissue while the dermis is composed of connective tissue. The hypodermis is not technically part of the skin, but it anchors the skin to muscle and stores fat (Marieb and Hoehn, pg.151). The epidermis is the outermost layer of the skin and its main function is for protection from invading microorganisms. It shields…

degrees of burn. Results: The layers of the human skin and the degrees of burn. Observation: The main purpose of this activity was to identify the layers of the skin and its structures. The first layer, the epidermis is the outer most layer and this layer we can see. The epidermis consist of four different types of cells and five different layers and it helps to…
