Sense: The Vomeronasal Organ "We are all more influenced by smell than we know." (Hercule Poirot) ....Murder in Retrospect, Agatha Christie Biologists have long realized that the noses of most vertebrates actually contain two sensory channels. The first is the familiar olfactory system, which humans possess. The second channel is the vomeronasal complex, a system that has its own separate organs, nerves, and connecting structures in the brain. The function of the vomeronasal system is the
research, a study by Stern and McClintock on pheromones in women's underarm secretion gives the most solid evidence for the existence of human pheromones ((5)). It has been hypothesized that the brain detects these pheromones through an organ known as the vomeronasal organ (VNO), by receptors, or by the terminal nerve in the nostrils ((5)). Despite the fact that pheromones and how they are detected in humans is controversial, it has been suggested that selectivity for certain pheromones might explain
when Case goes to Japan in hopes of finding a cure on Japan's black market. They have a big supplier of organs there. This demonstrates the struggle in Japan. In Case's time there is such a high demand for organs that they will sell them illegally over the black market. The black market most of the time represents the scum of society. There crime runs rampant. People will get killed for their organs, just so someone can make a few extra dollars. The next sign of this book being a dystopia is Ratz.
scientists; that the brain is an accommodating organ. It will attempt to carry out the same function, even when part of it is damaged, by redirecting the function to another area of the brain. As opposed to previous mainstream scientist's understanding that the brain is compartmentalized, it is now more acceptable that the individual "parts" of the brain could be somewhat interchangeable (1). For the purpose of scientific exploration, are the sensory organs interchangeable as well? Could a nose function
account for more than eighty-eight percent of new cases in this age group (Davidnow, 2004). Chlamydia is a disease that can cause permanent damage to the sexual organs. An estimated three million people are infected with Chlamydia each year (Witmer, nd). Once inside the blood, the microbes can spread to the joints, skin, and major body organs. With this disease, up to twenty percent of men may not have symptom but a bigger problem is that up to eighty percent of women do not experience symptoms.
maintenance of life depends upon various physiological and biochemical activities. The body is made up of many cells (e.g. brain cells). Many specialised cells group up to form a tissue (e.g. blood). Tissues group up to form organs (e.g. the heart), these organs can then conn... ... middle of paper ... ... page 566 Significance of homeostasis --------------------------- Homeostasis is so important that most disease is regarded as a result of its disturbance, a condition called
magician, this mans name was Flagg. He was evil and wanted to corrupt the kingdom. He had eventually put a poison in Rolands wine that peter took to him every night. He put a substance called Dragon Sand in it. What it does is it melts your interior organs and sets you ablaze until you are completely melted. When Roland died it had made it look like peter had killed him, because Flagg planted the remaining sand in peters room and since peter took him wine every night then it looked like peter had done
their exercise or manifestation depends on organization. 3. That the brain is an organ of all the propensities, sentiments, and faculties. 4. The brain is composed of many particular organs as there are different propensities, sentiments, and faculties which differ from one another. 5. That the form of the head or cranium represents the form of the brain, and thus represents the relative development of the brain organs. Gall linked the faculties with precise brain localizations through careful observation
The effects drinking has can cause long term problems. Drinking can affect an individual mental and physical abilities. It can cause slurr speach, flush skin, loss of balance, sexual problems, birth defects in pregnancy, and problems with socity. There are some positive effects to drinking as well as negative effects,although there are more negative effects than positive. For instant, moderate drinking can affect the blood and act as a blood thinner, which can have both positive and negative health
How long do you want to live? It is not surprising that no one gave me the answer: 1000 years, or, forever. Because we all know death is human faith.But today I want to tell you: Immortality can soon be reality.There’s no doubt that we’re living longer than previous generations. 100 years ago, the average human life span was 30 years. Today, we extend it to almost 70 years. So it is reasonable to ask: How much more can human life span increase?Over 4000 years ago, a Sumerian king seeks eternal life
In fig 5, Cardiac output shows the same trend in relation to heart rate from fig 3, as heart rate slows down approximately 32% (fig 3). Total peripheral resistance was increased in fig 2, this is so that more oxygen can be improved for the vital organs. The increased levels of total peripheral resistance is also to allow more of the blood ...
exists today. Many modern day sport hunters do not follow this ideal. A lot of hunters stuff and mount their kills as trophies, or decorations. This is a waste of the animal. Before the dead animal is stuffed, the taxidermist removes the internal organs and scrapes the skin clean. The waste is then dumped into a garbage bin and disposed of. This is an enormous waste of the animal. While some hunters do eat the animals they kill, and use most of it, the majority do not.
Gastrointestinal stromal tumors develop in the connective tissue and muscle layers in the wall of the colon and rectum. Lymphomas are cancers of immune system cells that typically develop in lymph nodes but may also start in the colon and rectum or other organs. Colorectal cancers are thought to develop slowly over a period of several years. Before a true cancer develops, there usually are precancerous changes in the lining of the colon or rectum. These changes might be dysplasia or adenomatous polyps. A
analogy represents society with the human body and social structures and institutions are represented by the body’s organs. For a human being to survive, the body must perform certain functions to solve problems and meet needs. For example, we must circulate blood, remove waste, and biologically reproduce. Survival depends on the individual organs and how they perform together. Each organ does something to keep the system going. In order for society to survive and keep order, individual institutions
animal around its environment, and controls the sensory structures. It has a top dorsal and bottom ventral on their body structure. Some characteristics that are identified with the Platyhelminthes are: bilateral symmetry, gas exchange by diffusion, organs for digestion, reproduction, excretion, and cephalization. The digestive tracts of free-living flatworms are branched. This animal uses diffusion to exchange oxygen into carbon dioxide across the surface of their body. Some interesting facts about
The Human Heart The human heart is an organ that pumps blood through the circulatory system into the human body. The human heart is a complex organ which has special parts, a complicated way of working and further requires multiple tasks to be done to keep the heart healthy. In, order for the human heart to work properly, it uses specific parts that allow it to run. With these specific parts, the human heart works in a particular way further explain. When certain defects are formed in the heart,
There are different levels of medical conditions. Some conditions may affect specific organs or systems within the body. This is the case with medical sanguinarians or med sangs. While all sanguinarian vampires drink blood to alleviate feelings of weakening health, med sangs drink blood to alleviate symptoms of a specific medical issue. The medical sanguinarian CJ! suffers from an irritable bowel. She has tried many different remedies and medications but has found that blood is the only thing that
and left ventricles. The atria work together simultaneously and then the ventricles will work in a synchronized manner. The atria will contract and then the ventricles will in tandem. Although it seems simple enough, the heart is one extraordinary organ that has a mind of its own. It all starts with the sinoatrial (SA) node in the upper right corner
