- Rating Newest Oldest. Best Answer: The Epidermis The epidermis is the outermost layer of the skin, and protects the body from the environment. The thickness of the epidermis varies in different types of skin; it is only .05 mm thick on the eyelids, and is 1.5 mm thick on the palms and the soles of the feet.

The Skin The deepest layer of the skin is called the subcutaneous layer, the subcutis, or the hypodermis. Like the dermis, the layer contains blood vessels and nerves for much the same reasons. Importantly, the subcutis contains a layer of fat. This layer of fat works alongside the blood vessels to maintain an appropriate body temperature.

Layers of the Skin The Epidermis. The epidermis is the outermost layer of the skin, and protects the body from the environment. The thickness of the epidermis varies in different types of skin; it is only .05 mm thick on the eyelids, and is 1.5 mm thick on the palms and the soles of the feet.he basal layer is the innermost layer of the epidermis, and contains small round cells called basal cells. The basal cells continually divide, and new cells constantly push older ones up toward the surface of the skin, where they are eventually shed.

The Integumentary System: The Dermal Layer Pretty gross, right? All those dead skin cells fall off the surface of your skin as new cells are made in the top layer of your skin called the epidermis. Underneath that layer is a deeper layer called the dermis. The dermis plus the epidermis make up the integument, or skin. The epidermis contains layers of cells that contain the protein keratin.

Surface Area of Human Skin Skin is composed of three layers: the epidermis (the outermost layer of skin -- about the thickness of a piece of paper), the dermis (the middle layer) and the subcutaneous layer (the deepest layer).

Picture of the Skin The skin is the largest organ of the body, with a total area of about 20 square feet. The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. Skin has three layers: 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, hair follicles, and sweat glands.

Thermal Burns Skin consists of three distinct layers: the epidermis, the dermis, and the subcutaneous layer (figure 1-1). The top layer, the epidermis, is attached to the second layer, the dermis. The dermis is thick, connective tissue. Individuals with thick skin have a relatively thick epidermis. Persons with thin skin have a thin epidermis. The subcutaneous layer, the third layer of skin, is located beneath the dermis and consists of areolar (minute spaces in tissue) and adipose (fat) tissues. The first skin layer is fixed to the second skin layer as though the two were glued together.

- Confidence votes 514. Humans have 3 major skin layers: 1. The epidermis is the outermost covering of the skin and it provides a weatherproof barrier. 2. The dermis is below the epidermis and it cushions the body from stress and strain. 3. The Hypodermis is below the dermis and is responsible for connected muscle tissue, bone, and skin.

Skin 101: The Epidermis, Melanin, and More The epidermis. This is the outermost layer of your skin. There are three sub-layers within the epidermis itself: the outer stratum corneum, the middle squamous cell layer, and the bottom basal cell layer.The stratum corneum is the visible part of the epidermis and is actually a layer of dead skin cells immediately on the skin's surface.This layer uses a protein called keratin to form a tough barrier between the outside world and the more vulnerable cells inside the skin and body. Keratinocytes or squamous cells are in the middle layer of the epidermis and produce keratin, the protein that forms the protective outer layer. 2  Keratin also is used to produce hair and nails.

Acantholysis The epidermis is the top most layer of the skin. 1  It consists of 4 layers, from deepest to most superficial: 2  Stratum basale (basal layer) 3  Stratum spinosum (spiny layer) 4  Stratum granulosum (granular layer) 5  Stratum corneum (horny layer)

What additional protective layer of protein surrounds some viruses-? The top layer of skin, called the epidermis, is the tough protective coating. It is made from keratin fibres, the same protein that makes hair and nails. 1 person found this useful. Edit.

Skin layers Your skin has three main layers: Epidermis — This is the layer you see. The surface is actually composed of dead skin cells that were made at the bottom of this layer and have risen to the top.This layer is constantly making new skin.

Simple Carbohydrates vs. Complex Carbohydrates Carbohydrates are an important nutrient found in numerous types of foods. Carbohydrates are made up of three components: fiber, starch, and sugar. Fiber and starch are complex carbs, while sugar is a simple carb. Depending on how much of each of these is found in a food determines its nutrient quality. Simple carbs are sugars.

How many layers of skin do humans have? Skin: dermal layers. The dermis, called true skin,  is the layer beneath the epidermis. Its major parts are collagen (a protein that adds strength), reticular fibers (thin protein fibers that add support), and elastic fibers (a protein that adds flexibility).

Your Largest Organ isâ¦ The top layer, which is visible on the outside of your body, is called the epidermis. The very top of this layer is actually dead cells, which are continually being replenished from below as younger living cells push the older cells upward. This cycle repeats about one thousand times during your life.

Structure, Functions and Problems of the Skin The epidermis is the relatively thin, tough, outer layer of the skin. Most of the cells in the epidermis are keratinocytes. They originate from cells in the deepest layer of the epidermis called the basal layer. New keratinocytes slowly migrate up toward the surface of the epidermis. Once the keratinocytes reach the skin surface, they are gradually shed and are replaced by newer cells pushed up from below.

Layers of the Skin The dermis is located beneath the epidermis and is the thickest of the three layers of the skin (1.5 to 4 mm thick), making up approximately 90 percent of the thickness of the skin. The main functions of the dermis are to regulate temperature and to supply the epidermis with nutrient-saturated blood.

The layers of your skin Epidermis is the top layer of the skin, the part of the skin you see. Dermis is the second layer of skin. It's much thicker and does a lot for your body. Subcutaneous fat is the bottom layer.

- Understanding the structure of the skin. Our skin is divided into three layers: the epidermis on the surface, the dermis in the middle, and the subcutaneous tissue deepest down. Each layer protects the body in a different way. The epidermis, the uppermost layer of skin, protects us from external irritation. It tends to be very thin, with a thickness of no more than around 0.1-0.3 mm. The epidermis is itself divided into four layers: the stratum corneum, the stratum granulosum, the stratum spinosum, and the stratum basale. Epidermal cells are constantly being created on a 28-day cycle of rebirth and decay. We call this the “turnover” of the skin.

What Are the Three Layers of Skin Called? Quick Answer. The top layer of skin is called the epidermis, the second layer is the dermis, and the third layer is the hypodermis. The skin is the body's largest organ, and it offers the first line of protection against bacteria and other harmful substances. The skin helps the body regulate heat and provides the sensation of touch.

Human Skin Layers The epidermis is the outer layer of the skin. This is the part we see. New cells are made in this layer constantly. The bottom of the epidermis is where this takes place. The new cells move up as they are ready to take their place in the middle of the epidermis.he epidermis is also where you will find melanin, which is produced by cells in the epidermis called melanocytes. Melanin is what gives our skin the color it has. The more melanin, the darker the skin. It provides some protection from the burning rays of the sun.
