Evolution Of The Nervous System Through Nine Animal Phylum - 1,502 words
The only multi-cellular animals without a nervous system are sponges. They do not have any nerve cells or sensory cells. Despite this, touch or pressure to the outside of a sponge will cause a local contraction of its body. Cnidarians The jellyfish and most all other forms of cnidarians, such as the hydra and sea anemone, are characterized by a nerve net. A nerve net is a series of interconnected nerve cells that conduct impulses around the jellyfishs entire body. The strength of the jellyfishs response is proportional to the strength by which the jellyfish is being stimulated. So, in other words, the stronger the stimulus is the stronger the reaction will be. Platyhelminthes The nervous sys ...

When we discuss our brain, we usually focus on the brains ability to think. That task alone is extremely complex and involved, but the brain also has many other tasks. Most of the time the brain is on autopilot, meaning that most of the activities preformed are just automatic. Our five senses; sight, sound, touch, taste, and smell, are automatically preformed in our brains. We don't have to think about how something sounds, we just hear it and we then interpret that sound. The largest area of our brain is the area that is set aside for vision, it is located in the occipital lobe. Dr. Gerard Guarniero has been blind since birth, a defect in which he has never been able to fix. Recently, he ha ...

Metabolic Muscular And Nervous Systems - 1,672 words
... ws the cross-bridge to detach and re-attach to another active site on an actin molecule. This contraction cycle is repeated as long as free calcium is available to bind the troponin and ATP is available to provide the energy. The signal to stop contraction is the absence of the nerve impulse at the neuromuscular junction. When this occurs, an energy requiring calcium pump located within the sarcoplasmic reticulum begins to move the calcium back into the sarcoplasmic reticulum. This removal of calcium from troponin causes tropomyosin to move back to cover the binding sites on the actin molecule and cross-bridge interaction ceases. It is possible for skeletal muscle to exert force without ...

Teenage Drinking - 1,551 words
Teenage drinking is something that goes on every day. No matter how many videos you show to kids about drinking they will still drink. Surveys show that the average teen seventeen and up spends $475.00 a year on liquor, mostly beer. [That's more than books, soda, coffee, juice and milk combined]. Most parents don't know about teenage drinking unless they catch their kids doing it. Some parents say, "their kids would never do that ", and they're the ones whose kids probably drink more than the average teen. (MADD, 00) One might ask, how do kids get alcohol? Alcohol is almost as easy to get as a carton of milk, except a teen has to get someone older like a friend, brother or even someone off o ...

1984: The Quintessential Negative Utopia (Or How to become really depressed about the future of the human condition in 267 pages or less.) 1984 is George Orwell's arguably his most famous novel, and it remains one of the most powerful warnings ever made against the dangers of a totalitarian society. George Orwell was primarily a political novelist as a result of his life experiences. In Spain, Germany, and Russia, Orwell had seen for himself the peril of absolute political authority in an age of advanced technology; he illustrated that peril harshly in 1984. Orwell's book could be considered the most acknowledged in the genre of the negative utopian novel. The mood of the novel aims to portr ...

The phrase "the place where there is no darkness" works as a symbol of hope throughout the novel, as Winston recalls the dream in which O'Brien tells him about the place and says they will meet there one day. The phrase therefore orients Winston toward the end of the novel, when the phrase becomes bitterly ironic: the place where there is no darkness is the Ministry of Love, where the lights remain on in the prisons all day and all night. Winston's affair with Julia becomes an established part of each of their lives, leading up to Winston's meeting with O'Brien. Despite the risk given the thoroughnes ...

Carvers Vision - 1,977 words
In private desperation, Raymond Carver's characters struggle through their lives, knowing, with occasional clarity, that the good life they had once hoped would be achieved through hard work will not come about. In many ways, Carver's life was the model for all of his characters. Married to Maryann Burk on June 7th, 1957, at nineteen, and having two children by October of 1958, the Carvers' life was decided for years to come. Early on, Carver felt, along with his wife, that hard work would take care of nearly everything. "We thought we could do it all," he said in one interview, "We were poor but we thought that if we kept working, if we did the right things, the right things would happen" ( ...

The Inuit People Of The Arctic - 1,403 words
The Inuit are one of the many self-designations of the Eskimo people. They are considered to be of Asian decent, which is noticeable from their small hands and feet. Another distinguishing feature is the appreciable percentage of the B blood type, which seems to be totally absent from the American Indian, whom they are usually mistaken to be descendants of (Mastny 25). These Inuit are scattered in small communities across Northern Alaska, northern Canada, Greenland, and the Chukotka region of Eastern Siberia. The Inuit in these regions total around 150,000 that makes up barely 4 percent of the Arctics total population of 3.8 million (Mastny 25). The origins of the Inuit living in this region ...

Multiple Sclerosis - 742 words
Multiple Sclerosis is a disease of the central nervous system, the nerves that make up the brain and spinal cord. This disease is commonly known as MS. Its cause is unknown, it cannot be prevented, and neither a cure or a safe and effective treatment has been able to halt its progression so far. It is not fatal, and much progress is being made in treating symptoms and identifying mechanisms that trigger this disease. Sclerosis comes from the Greek word skleros, which means hard. Multiple sclerosis refers to multiple areas of patchy scarring, or plaques, that result from demyelination, which means destruction of myelin, a fatty insulation covering the nerve fibers. Myelin is made from layers ...

TOXIC SHOCK SYNDROME (TSS) was discovered almost 20 years ago. At first no one knew what was causing it, although it was quickly linked with "superabsorbent" tampons (which are no longer on the market). Eventually researchers discovered that a poison produced by a type of bacteria known as Staphylococcus aureus is responsible for TSS. Some theorized that tampons may produce small ulcerations, which allow bacteria to enter the body. Another theory is that stagnating blood within or behind the tampon may permit the bacteria to grow. Most cases of toxic shock syndrome have been associated with tampon use. However, a few have been reported in women who use a diaphragm for birth control, or durin ...

Diabetes mellitus is a group of diseases characterized by high levels of blood glucose resulting from defects in insulin secretion, insulin action, or both. Diabetes can be associated with serious complications and premature death, but persons with diabetes can take measures to reduce the likelihood of such occurrences. 15.7 million people -- 5.9% of the population -- have diabetes.

Aids - 1,384 words

You can choose between anonymous tests, in which you do not give your name to the HealthCare provider, or confidential tests, in which you do give your name.

These antibodies may not appear in your blood until three to six months after HIV infection. Therefore, a negative test for HIV doe ...
