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

Context: A lonely old woman who longs for a child is given a seed by a good witch. When planted, the seed grows into a flower, and inside the blossom is a tiny girl the size of the old woman's thumb. The old woman names the girl Thumbelina and raises her as her own. Although Thumbelina loves her mother, she craves companionship from someone her own size. One night, Cornelius, the fairy prince, stumbles upon Thumbelina after hearing her beautiful singing. The two take a ride on Cornelius' bumblebee, and fall in love; during this ride Mrs. Toad and her son Grundel are enchanted by Thumbelina's singing. Cornelius promises to return the next day, but after he's gone, Mrs. Toad kidnaps Thumbelina from her bed and takes her away. Thumbelina awakens on Mrs. Toad's show boat. Mrs. Toad wants Thumbelina to join their troupe and marry Grundel, who is in love with her. They leave Thumbelina alone on a lily pad in order to fetch a priest, but a friendly swallow, Jacquimo (the narrator of the film), overhears Thumbelina's cries for help and frees her. Jacquimo's friends, the jitterbugs, promise to help Thumbelina get home safely while Jacquimo sets off to find Cornelius. Meanwhile, Cornelius learns of Thumbelina's kidnapping and ventures out to find her. While trying to get home, Thumbelina is ambushed by Berkeley Beetle, who scares the jitterbugs away. He is enamoured with her singing, and promises to show her the way home if she sings at his Beetle Ball first. Thumbelina agrees, but when she's received poorly at the Beetle Ball, Beetle kicks her out without helping her. Winter is approaching. Jacquimo accidentally impales his wing on a thorn and is knocked out by the cold, while Cornelius falls into a lake and is frozen in ice. Grundel, who is searching for Thumbelina, finds Beetle and discovers she is in love with Prince Cornelius and upon some convincing from Beetle, decides to find and kidnap Cornelius to lure Thumbelina to him. Grundel forces Beetle to help him as Grundel steals his wings and won't return them until Beetle has found and captured Cornelius. Thumbelina is taken in by Miss Fieldmouse, who tells her that Cornelius has died. The two visit Miss Fieldmouse's neighbor, Mr. Mole who tells them about a dead bird he found in his tunnel earlier that day. It turns out to be Jacquimo, who Thumbelina discovers to be only unconscious. Mr. Mole wishes to marry Thumbelina; heartbroken over Cornelius's death, Thumbelina accepts. Jacquimo awakens under Thumbelina's care and leaves to find Cornelius, refusing to believe that he is dead. Meanwhile, Beetle brings Cornelius's frozen body to Grundel and informs him that Thumbelina is going to marry the Mole. After the two leave to stop the wedding, the young jitterbugs thaw Cornelius's body out. At the wedding, Thumbelina realizes at the last moment that she can't marry someone she does not love and refuses to take the vows. Grundel and Beetle crash the wedding, but Thumbelina flees from them and Mr. Mole. Cornelius intercepts the crowd and confronts Grundel, the ensuing fight resulting in them both falling into an abyss. Once outside and free, Thumbelina is reunited with Jacquimo, who takes her to Cornelius' kingdom, the Vale of the Fairies. Cornelius appears, having survived the fall, the pair are reunited, and Thumbelina accepts his proposal of marriage. The two kiss, and Thumbelina is granted her own wings. With Thumbelina's mother and the fairy court in attendance, Thumbelina and Cornelius are married and depart on their honeymoon on Cornelius's bumblebee. Images shown during the credits reveal that Beetle resumed his singing career and had gotten his wings back, Ms. Fieldmouse married Mr. Mole, and Grundel also survived the fall with minor injuries and married a female toad (implying that he lost interest in Thumbelina).
Question: What is the name of the prince Thumbelina loves?
