Epidermis

and glands. • The skin- The cutaneous membrane is the toughest organ that the human body has, and it has three 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 make the skin solid and strong. The epidermis…

(cutaneous membrane), hair, nails, sweat (exocrine) glands, and other side components as well. The skin has various layers that go in a specific order. The epidermis is the outermost layer that you can…

Epidermis is the tough outermost layer of the skin, and is made up of the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale. It is mainly comprised of the protein keratin, squamous epithelial cells and melanin. The epidermis acts as a waterproof barrier and the melanin absorbs ultra violet light to prevent burns, inflammation, and swelling of the skin. Dermis is the lower layer of the skin that contains collagen, nerve fibers, lymph vessels, and blood…

1. The three major layers that make up healthy skin are the epidermis, dermis, and the subcutaneous tissue (hypodermis). The epidermis is a keratinized stratified squamous epithelium that resists abrasion and reduces water loss. It consists of four distinct cell types and five layers. The dermis, the second major skin region containing strong, flexible connective tissue. It is composed of dense irregular connective tissue. Also, the dermis contains the blood vessels, nerve fibers and lymphatic…

Somatic epidermal stem cells at the basal layer of epidermis is responsible to maintain skin homeostasis. When cutaneous injuries occur, skin homeostasis and integrity is damaged, leading to fatal traumatizing under severe conditions. Skin wound healing is an intrinsic self-saving chain-reaction, which is crucial in facilitating the replacement of damaged or lost tissue. Immense amounts of research have uncovered the mechanisms underlying this complex and highly regulated process. It is commonly…

structures include hair, nails and exocrine glands. Cutaneous membrane is the epidermis and papillary layer of the dermis. The papillary layer is the uppermost layer of the skin. The job of a integumentary system is to protect. The skin provides a protective barrier from the external environment and prevents dehydration by storing water and fat. It acts as a food source protecting our body from the effects of starvation.…

The skin is a major component of the integumentary system and forms a defensive barrier that protects the internal environment against external forces (Seeley, 2008). Studies carried out by Lowes, Suárez-Fariñas, and Krueger (2013), Cargill et al. (2007) and Tsoi et al. (2012) show that psoriasis vulgaris is a homeostatic disorder of the skin that interrupts the normal proliferation, differentiation and maturation of epithelial cells in the stratum corneum. The focul site of psoriasis vulgaris…

The skin is said to be the largest performing organ in the body due to its three layered skin which all perform different tasks simultaneously. The epidermis (outer layer) and the dermis (inner layer) are the two main top layers of the skin followed by the lower subcutaneous tissue. The epidermis is the main component of the skin because it contains millions of important cells called melanocytes (Gohara and Perez 1). These melanocytes produce melanin which provides the skin with pigment (skin…

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…

The skin is organized in two parts: the epidermis and the dermis. The epidermis is the thin outer covering of the skin. It serves as a permanent protective barrier that helps to keep out everything from water to microorganisms. Additionally, it has the task to renew itself if cut or damaged in anyway. Furthermore, the epidermis also help to produce a water resistant protein called keratin, which helps the growth of hair and fingernails. The dermis is the inner layer of the skin that is mostly…
