Q: Context: From the outside, the skin looks plain and simple, as you can see in Figure 16.5. But at a cellular level, theres nothing plain or simple about it. A single square inch of skin contains about 20 blood vessels, hundreds of sweat glands, and more than a thousand nerve endings. It also contains tens of thousands of pigment-producing cells. Clearly, there is much more to skin than meets the eye! For a dramatic introduction to the skin, watch this video: MEDIA Click image to the left or use the URL below. URL: The skin is only about 2 mm thick, or about as thick as the cover of a book. Although it is very thin, it consists of two distinct layers, called the epidermis and the dermis. You can see both layers and some of their structures in Figure 16.6. Refer to the figure as you read about the epidermis and dermis below. The epidermis is the outer layer of skin. It consists almost entirely of epithelial cells. There are no blood vessels, nerve endings, or glands in this skin layer. Nonetheless, this layer of skin is very active. It is constantly being renewed. How does this happen? 1. The cells at the bottom of the epidermis are always dividing by mitosis to form new cells. 2. The new cells gradually move up through the epidermis toward the surface of the body. As they move, they produce the tough, fibrous protein called keratin. 3. By the time the cells reach the surface, they have filled with keratin and died. On the surface, the dead cells form a protective, waterproof layer. 4. Dead cells are gradually shed from the surface of the epidermis. As they are shed, they are replaced by other dead cells that move up from below. The epidermis also contains cells called melanocytes. You can see a melanocyte in Figure 16.7. Melanocytes produce melanin. Melanin is a brown pigment that gives skin much of its color. Everyones skin has about the same number of melanocytes per square inch. However, the melanocytes of people with darker skin produce more melanin. The amount of melanin that is produced depends partly on your genes and partly on how much ultraviolet light strikes your skin. The more light you get, the more melanin your melanocytes produce. This explains why skin tans when its exposed to sunlight. The dermis is the inner layer of skin. It is made of tough connective tissue. The dermis is attached to the epidermis by fibers made of the protein collagen. The dermis is where most skin structures are located. Look again at Figure pain, pressure, and temperature. If you cut your skin and it bleeds, the cut has penetrated the dermis and damaged a blood vessel. The cut probably hurts as well because of the nerve endings in this skin layer. The dermis also contains hair follicles and two types of glands. You can see some of these structures in Figure 16.8. Hair follicles are structures where hairs originate. Each hair grows out of a follicle, passes up through the epidermis, and extends above the skin surface. Sebaceous glands are commonly called oil glands. They produce an oily substance called sebum. Sebum is secreted into hair follicles. Then it makes its way along the hair shaft to the surface of the skin. Sebum waterproofs the hair and skin and helps prevent them from drying out. Sweat glands produce the salty fluid known as sweat. Sweat contains excess water, salts, and other waste products. Each sweat gland has a duct that passes through the epidermis. Sweat travels from the gland through the duct and out through a pore on the surface of the skin. You couldnt survive without your skin. It has many important functions. In several ways, it helps maintain homeostasis. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. Melanin in the epidermis absorbs ultraviolet light. This prevents the light from reaching and damaging the dermis. The skin helps maintain a constant body temperature. It

Q: Context: Coming off a primetime victory over Cincinnati, the Colts flew to Reliant Stadium for an AFC South rematch with the Houston Texans. Heading into this game, Indianapolis had never lost a game to the Texans, winning their first 9 games against them. In the first quarter, the Colts got an early shock as RB Ron Dayne ran for a 3-yard touchdown and a 6-yard touchdown run. Indianapolis would respond with 37-yard touchdown pass from QB Peyton Manning to WR Marvin Harrison. In the second quarter, the Colts tied the game with Manning completing a 9-yard touchdown pass to WR Aaron Moorehead. However, Houston reclaimed its lead with QB David Carr's 3-yard touchdown pass to RB Vonta Leach. In the third quarter, Indianapolis crept closer with K Adam Vinatieri making a 33-yard field goal for the only score of the period. In the fourth quarter, the Texans responded with kicker Kris Brown's 42-yard field goal. Afterwards, the Colts tied the game with Manning hooking up with Harrison again on a 7-yard touchdown pass, Harrison's second of the game. However, Houston managed to pull off a huge upset with Kris Brown's game-winning 48-yard field goal as time expired, giving Indianapolis their first ever loss against them. With the loss, the Colts fell to 11-4. Colts QB Peyton Manning finished the game 21 of 27 for 205 yards passing with three touchdowns and Texans QB David Carr finished with 163 passing yards on completing 16 of 23 passes with one touchdown. Rookie RB Joseph Addai ran the ball 15 times for 100 yards and former Heisman Trophy winner Ron Dayne finished the game with 153 rushing yards on 32 carries. After this game, the Colts were now 11-4, having lost 4 of 6 after a 9-0 start and dropped to 4-4 on the road.
