The Skin Or Integument System

The Integumentary is a vast organ system composed of exocrine glands, hair, nails, and the most commonly known organ, the skin. As a large system, it can be susceptible to many different types of diseases, one of these diseases are called Psoriasis. This affects a large portion of the Integumentary system, the skin. Psoriasis are considered to be a widespread, common and recurring disease that can be chronic at times. Psoriasis are defined by its appearance of light silver in color, flaky, rash on many parts of the Epidermis.

The integumentary system can be broken down into three main categories the Epidermis, Dermis, and Subcutaneous layer each of which contain certain specialized skin derivatives including hair, nails, and several kinds of glands.

The Integumentary system is defined as “an organ system consisting in the skin, hair, nails, and exocrine glands” (Integumentary System, 1999). This systems main purpose is to protect the body from the environment around it. The skin covers and protects tissues, nerves, veins, and muscles of the body. The hair and nails give extra strength in reinforcing the skin while keeping the body warm and protecting the skin from harmful UV rays. The exocrine glands of the skin include the sudoriferous glands, sebaceous glands, and the ceruminous glands. Each exocrine gland has a different function as well as location in the skin. The following text will explain the effects of melanoma on the integumentary system.

The three layers that make up healthy skin: Epidermis, Dermis and Hypodermis. Epidermis is composed of keratinized, stratified squamous epithelium. This layer provides a thick, water proof protective covering over the underlying skins. The dermis layer is composed of primarily of dense, irregular, fibrous connective tissue that is rich in collagen and elastin. The dermis contains blood vessels, nerve ending, and epidermally derived cutaneous oranges such as sweat glands, sebaceous glands and hair follicles. The last layer is Hypodermis this layer is composed primarily of loose dead skin. The fat layer provides cushioning and insulation for

The skin is the largest organ of the body and it acts as a waterproof protector for all of the internal organs, it is comprised of several layers including the Epidermis which is the outer layer and is a protective multi-layered self renewing structure which varies in thickness depending on which part of the body it covers. Under this is the Dermis, this is a layer of connective tissue which provides the skins elasticity and strength, it also contains sensory nerve endings, blood and lymph vessels, sebaceous and sweat glands. Under this layer is the Subcutaneous fat layer, this layer separates the skin from the underlying bone and muscle with a rich blood supply it also serves as an insulator and energy store. Pressure ulcers develop

The outermost layer of the epidermis is known as the stratum corneum, it is water resistant and when not damaged, it protects the body from foreign substances such as bacteria, virus etc. it also ensures the protection of muscles, blood vessels, nerves and internal organs. The skin is also thicker in regions that requires more protection such as the sole of the feet and palms.

The outer germ layer is the ectoderm that forms the outer part of the body (the skin) and the nervous system. The endoderm, the inner germ layer, forms many inner structures, including the digestive tract and many glands associated with it. Lastly, the mesoderm is the middle layer which forms much of the skeleton and muscles.

There are three primary layers of the skin: the outer layer, the epidermis and the layer beneath, the dermis and the hypodermis. The epidermis is thin, tough and waterproof while protecting the body from outside bacteria invading the body. It also contains keratinocytes which are from the basal layer which is the deepest layer of the skin. The keratinocytes reach up to the epidermis, shed and new ones form again. The dermis is the second layer of the skin and is the thickest. It is made from fibrous and elastic tissues which are made from fibrillin, elastin and collagen to create the strength and flexibility. It also contains sweat and oil glands, nerve endings, blood vessels and hair follicles. Sweat glands help the body cool off during heat

The layers of the epidermis from deep to most superficial are the stratum basale, stratum spinosum, stratum grandulosum, stratum lacidum, and the stratum corneum. Each of these layers are unique due to the type of cells located in them which they are named after. They all together make up the epidermis, an avascular, superficial, and made up of epithelial cells.

Your body is an entangled framework that comprises of numerous subsystems that assistance to keep it working legitimately. These subsystems fill an assortment of needs and require required materials to work appropriately, and also methods for imparting data to different parts of the body. In this way, the skin and different parts of the integumentary framework work with different frameworks in your body to keep up and bolster the conditions that your cells, tissues, and organs need to work appropriately.

The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

The skin is the largest organ of the body, the skin protects us from microbes and the elements, it also helps regulate body temperature, and permits the sensations of touch, heat, and cold. There are three layers of skin, this includes the epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone, the dermis, beneath the epidermis, contains tough connective tissue, which gives the skin flexibility and strength, hair follicles, produce the various types of hair found throughout our body, sweat glands, these produce sweat in response to stress and heat, blood vessels of the dermis are what help regulate our body temperature, and nerve ending, which sense pain, pressure and temperature and the hypodermis, the deeper internal tissue is made of fat and connective tissue, this functions as a protective shield for

Stratum Corneum this layer is the outer most layers; it is formed from numerous layers of compressed scale- like, overlapping cells. What makes up the surface of the skin is corneocytes, which are commonly called ‘dead skin cells’. Keratinocytes are found in the epidermis they travel up through the layer where they are formed into corneocytes. The stratum corneum layer protects against lights, chemicals, water loss, heat and bacteria.

In conclusion the skin plays an important role in the maintenance of homeostasis. It is an important barrier to infections, and diseases. The skin also plays a part in the feedback loop that regulates body temperature and synthesizes important vitamins for our

The functions of the integumentary system are far more important than most people think. Perhaps it is commonly known that this system, known as the skin, keeps the body together and protects the inner aspects of the body from harm, or cools the body. Those functions are overly simplified and only a fraction of the role this system plays in maintaining the balance, also known as homeostasis, of the body. It can be said that this system is the first line of defense or regulation. It provides these functions: resistance to trauma and infection, barrier functions, Vitamin D synthesis, sensation, and thermoregulation to fill its role (Saladin, Sullivan, & Gan, 2015, p. 177- 178).
