The outer most layer of the skin or Epidermis contains stratified squamous, keratinized, epithelial tissue; which lacks blood vessels, and the cells are packed closely together (Sloane, 1994, p.85)

The skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of the skin is around 3000sq inches depending on age, height and body size. As well as the nails, hair, sweat glands and the sebaceous glands, the skin forms the integumentary system. Besides oroviding protection to the body, the skin also helps regulate body temperature, helps your

Skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of skin is around 3000 sq inches or roughly around 19,355 sq cm depending on age, height, and body size. The skin, along with its derivatives, nails, hair, sweat glands, and sebaceous glands forms the integumentary system. Besides providing protection to the body the skin has a host of

1. The clear, keratinized portion of a fingernail is known as the nail _PLATE_. It has a root, body, and free edge.

The skin is divided into three different parts including the epidermis, dermis, and hypodermis. The epidermis is the outermost layer of the skin. This region of the skin has no blood cells or blood vessels running through it. All of the nutrients that the epidermis needs are received through diffusion from the dermis. The epidermis is made up of stratified squamous epithelial cells. The epidermis is made of five separate layers: the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and the stratum corneum. Starting at the innermost layer, the stratum basale is where mitosis of keratinocytes takes place. This layer of the epidermis also contains melanocytes which give the skin it’s pigment. As mitosis takes place in the stratum

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

Skin is the largest organ on the body. It has two layers: the thin outer layer is made up of dead skin cells that are constantly shed and replaced by new cells. The thick inner layer is made up of blood vessels, nerves, and hair follicles, which contain glands. The glands in the hair follicles produce an oily substance called sebum, which keeps the skin and hair from drying out. Daily washing will keep the skin on the face and other areas of the body clean by removing the dirt, oil, and dead cells before they can accumulate.

1. Decide if the mineral is metallic or non-metallic based on its luster and streak.

The blood circulates around the body. The heart contract and relax, this mechanism of heart makes the blood to flow in the arteries to the body from heart and come back from body to heart through veins. The arteries carry oxygenated blood or oxygen rich blood and the veins carry deoxygenated blood or oxygen poor blood. This flow creates the pressure on the arterial wall and the pressure that is exerted on the arterial wall is known as blood pressure. Blood pressure is expressed by the

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 business letter form that the text says imparts a feeling of directness without a strong personal touch is the ________________ form.

Part II: For the following questions, provide your response in short-answer format (2–3 detailed sentences each). Use this Phase’s activities and resources to assist you in answering.

The dermis contains elastic and fibrous tissues such as fibrillin, collagen and elastin. These tissues gives

As you have seen, a pulse is measured as the distention of an artery that can be felt each time the heart contracts. Pulse is measured in number of beats per minute. You can measure pulse anywhere an artery passes close to the skin. Clinically, it is most common to measure heart rate in the radial artery on the inside of the wrist. The figure shows you the procedure.

Stratum Granulosum is another shallow layer; it is made up 3 to 5 layers of flat packed grainy cells called kertaohylain cells which act similar to a water filter, to absorb any foreign bodies. This eases water loss and keeps up hydration in the skin.
