CHAPTER 4 the Integumentary System
CHAPTER 4 The Integumentary System LEARNING OBJECTIVES Upon completion of this chapter, you should be able to: • Name the two layers of the skin. • Name the accessory structures of the integumentary system. • Build and pronounce medical terms of the integumentary system. • Name the disorders and treatments relating to the integumentary system. • Name the major classifi cations of pharmacologic agents used to treat skin disorders. • Analyze and defi ne the new terms introduced in this chapter. • Interpret abbreviations associated with the integumentary system. 53 54 PART TWO • BODY SYSTEMS Introduction The largest organ of the body is the skin. The skin covers the entire body—more than 20 square feet on average—and weighs about 24 pounds. It is part of the integumentary system, which also includes the accessory structures: hair, nails, and sebaceous (oil) and sudoriferous (sweat) glands. Integumentum is Latin for “covering” or “shelter.” The physician who specializes in the diag- nosis and treatment of skin disorders is called a dermatologist (dermat/o being one of the com- bining forms for skin). Coupling the root dermat/o with the previously learned suffi x -logy gives us the term dermatology , which is the term for the specialty practice that deals with the skin. Word Elements The major word elements that relate to the integumentary system consist of various anatomical components, accessory structures, colors of the skin, and abnormal conditions. The Word Ele- ments table lists many of the roots, their meanings, and examples associated

The Integumentary System
The Integumentary System THE INTEGUMENTARY SYSTEM Skin is the system of the body that makes an individual beautiful! Skin/fur coloration allows animals to be camouflaged. *The skin is the largest organ of the body. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system. The total surface area of the skin is about 1.8 m² and its total weight is about 11 kg. The skin gives us our appearance and shape. Anatomy of the Skin • Skin is made up of two layers that cover a third fatty layer. The outer layer is called the epidermis; it is a tough protective layer. The second layer (located under the epidermis) is called the dermis; it contains nerve endings, sweat glands, oil glands, and hair follicles. Under these two skin layers is a fatty layer called the subcutaneous tissue, or hypodermis. 1 • The dermis is home to the oil glands. These are also called sebaceous glands, and they are always producing sebum. Sebum is your skin's own natural oil. It rises to the surface of your epidermis to keep your skin lubricated and protected. It also makes your skin waterproof. • Skin is alive! It's made of many thin sheets of flat, stacked cells. Older cells are constantly being pushed to the surface by new cells, which grow from below. When the old ones reach the top, they become wider and flatter as they get rubbed and worn by all your activity. And, sooner or later, they end up popping off like tiles blown from a roof in a strong wind.

The Integumentary System (In Teg Yoo MEN Tuh Ree) Skin, Tissues, and You the Integumentary System Is the Body’S Outer Covering
The Integumentary System (In teg yoo MEN tuh ree) Skin, Tissues, and You ! " The Integumentary system is the body’s outer covering. It has the task of physically separating the body from the external environment. This is the first key to homeostasis. ! " Homeostasis: The internal stability or “steady state” maintained by your body. We maintain a body temperature of 98.6ºF (37ºC) ! " The Integumentary system isn’t perfect. Cuts and other injuries break the barrier of the system and allow microorganisms to enter the body. Also, extensive exposure to the sun can cause damage to the tissue. Other harmful agents can damage the system as well. http://academic.kellogg.edu/herbrandsonc/bio201_mckinley/f5-1_layers_of_the_inte_c.jpg The Skin and Tissue Tissues ! " Your body contains 250 different types of cells. ! " Groups of similar cells with common function are called tissues. ! " Tissues protect the body, connect body parts together, some lift and move the body, some transmit http://asweknowit.net/images_edu/dwa5%20tissues.jpg information. Epithelial Tissue ! " Epithelial tissue: sheets of closely packed cells that cover the entire surface of your body and form the lining of your internal organs, many different types all serve the general function of protecting the tissues and organs they cover !

Body Systems Work Together by Cindy Grigg
Body Systems Work Together By Cindy Grigg 1 You know that your body is made of cells. When groups of cells do the same kind of work, they are called tissues. The word tissue comes from a Latin word meaning to "weave." Cells that make up tissues are sometimes "woven" together. 2 You have four main types of tissues: epithelial, nervous, muscle, and connective tissue. Epithelial tissue covers the outside of the body. It also lines organs and cavities. Nervous tissue sends electrical signals. Muscle tissue helps you move. Connective tissue joins bones and cushions organs. 3 When groups of tissues work together, they are called organs. Some examples of organs are the heart, lungs, skin, and stomach. When organs work together, they are called systems. For example, your heart, lungs, blood, and blood vessels work together. They make up the circulatory system. 4 There are eleven systems in the human body: muscular system, respiratory system, digestive system, integumentary system (skin), skeletal system, circulatory (or cardiovascular) system, excretory (or urinary) system, reproductive system, nervous system, lymphatic system, and endocrine system. Each system has a special job. 5 All of your body systems have to work together to keep you healthy. Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide. 6 Your digestive system absorbs water and nutrients from the food you eat. 7 Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin.

INTEREST GRABBER – NOTEBOOK #1 AN IMPORTANT PROCESS While walking along a dusty path, you begin to cough. As you continue your walk, a small insect comes flying toward you. You blink and then duck so that it misses you. These actions are just a few examples of homeostasis. Homeostasis is the process by which organisms keep internal conditions relatively constant despite changes in their external environments. 1. List three other examples of homeostasis that occur in organisms. 2. Why is homeostasis important to an organism? INTEREST GRABBER 1. List three other examples of homeostasis that occur in organisms. Accept all reasonable student examples that show an understanding of homeostasis. 2. Why is homeostasis important to an organism? Homeostasis allows an organism to remain in balance with its environment. If homeostasis is not maintained, it can harm the organism or result in the death of the organism.

Defences: the Integumentary System
Defences: the integumentary system Components The integumentary system consists of the skin and its derivatives, including hairs, nails, sweat glands and sebaceous glands. Functions The defence of the body against invaders involves two systems, the integumentary system and the immune system. These systems interact to defend the body. The skin acts as a barrier between the external environment and the rest of the body. It retains body fluids and defends against the entry of invaders such as viruses, bacteria and parasites. It also helps to maintain a constant body temperature. Figure 1 Beneath the skin. Skin contains receptors that sense, for example, temperature, touch and pain. In sunlight vitamin D is synthesised in skin. Recent research has shown that the skin plays an important role in immunity. Key mechanisms Epidermis The epidermis of the skin consists of many layers of cells. On the inside they are living Stratum corneum and rapidly dividing. As cells are continually Stratum lucidum lost from the outer surface, new cells are Stratum granulosum formed below, pushing up new replacement layers. The outer layers become progressively keratinised, dead and flattened. The keratin Stratum spinosum is progressively cross linked as the cells mature. When they die it forms a tough airtight and almost waterproof layer at the surface. Stratum basale Dermis Dermis The dermis is immediately below the Figure 2 Structure of the epidermis. epidermis. It is a connective tissue layer containing many elastin (stretch) and collagen (strength) fibres, together with a variety of sensors (specialised nerve endings) and numerous blood vessels. Sebum secreted by the sebaceous glands helps create a skin surface that is hostile to many pathogens.
