significantly contributes to homeostasis (McCorry, 2006). Most of the sensory input is from the thoracic and abdominal viscera and is transmitted to the brainstem by afferent fibers of the cranial nerve X which is the vagus nerve. After the input is integrated the response is carried out by the transmission of nerve signals of the preganglionic autonomic neurons. So what are some functions of the autonomic nervous system one may ask? Blushing (my favorite) is a response from the frontal cortex and involves
Blue Whales The Blue whale is the largest creature of the sea, in fact, it is the largest creature known to man. Contrary to what most people think, even though Blue whales live in the sea, they are mammals. They breathe air, have their babies born alive and can live anywhere from 30 to 70 years. The Blue whale is a baleen whale, and instead of having teeth, Blue whales have around 300-400 baleen plates in their mouths. They fall under the category of the rorquals, which are the largest
Pectin is a complicated branched structure of acidic structural polysaccharides, established in fruits and bast fibers. Most of the structure consists of homopolymeric partially methylated poly-α-(1-4)-D-galacturonic acid residues, but there are substantial 'hairy' non-gelling areas of alternating α-(1-2)-L-rhamnosyl-α-(1-4)-Dgalacturonosyl sections containing branch-points with mostly neutral side chains (1-20 residues) of mainly L-arabinose and D-galactose (rhamnogalacturonan-I). Pectin is the
Stiffness The effect that this additive has on the polymer in terms of stiffness is that the fillers are very useful because it makes the polymers very strong and stiff. This makes it hard to break. Service life The effect of fillers on polymers is that they are very beneficial because they don’t get ruined for a long time. Glass fillers are
had to do an I-search, I was overwhelmed by the choices. I made many changes before finally settling on this topic. When I first though of how to make silk, I didn't think that it would be that hard with the right tools. Although I knew that the fibers came from the silk worm's cocoon I still didn't know how they got it unraveled. I also thought that they only made silk in China. There are many things that I didn't know about making silk. When I thought of doing this topic I didn't think that it
Bone loss and corresponding gingival recession are the first symptoms to be seen in the caries process. These result in exposed root surfaces, which are more prone to forming caries because caries does not form in the root surface while periodontal fibers are still attached. Clinically, the lesion starts on the root surface. It has been found that root caries spreads in a lateral or circumferential manner, and over time can extend completely around the tooth, undermining the enamel. (Wilkins) In general
The advantages of using sandwich composites is that they provide mechanical properties to much lower weight than other materials like metals and concrete. They have high stiffness which gives high flexural rigidity, high tensile and compressive strength, good impact resistance, better surface finish, etc. Sandwich composite materials also enable designers to engineer with extreme precision to their loading requirements. Core is one of the variables in a sandwich composite that enables this due to
The substantial improvement of mechanical properties of polymer nanocomposites can be attributed to high rigidity and aspect ratio of nanoclay combined with good affinity through interfacial interaction between polymer matrix and dispersed nanoclay. It is well reported that polymer nanocomposites have excellent barrier properties against O2, CO2 and water vapor. This depends on the type of clay, i.e., compatibility between clay and polymer matrix, structure of nanocomposites and aspect ratio of clay
has millions of nephrons which are the basic unit of the kidney. The kidney is divided into two layers. The outer cortex and the medulla. When the outer cortex is stripped off you then get the medulla. The inside you have a thick mesh of muscular fibers. This is also smooth, and very even. It is very red in color, unlike the outside which is of brownish-purplish coloring. It is more red in color because it has tiny blood vessels. The kidneys are located in the posterior part of the abdomen, on both
“clean” and acceptable. Rules or “margins” regarding eating, drinking, and socializing between classes were strictly followed because one’s home and table were the groundwork for empowering ancient Rome (68). When margins are no longer clear, the fibers that collate a national culture begin to tear at the seams. On the macrocosmic level, ancient Roman society employed a patronal system, which was upheld by a sense of moral duty that extended through the hierarchical ranks down to the most destitute
quite well known and admired, not everyone fully shared his beliefs. Niccolo Machiavelli, for instance, seemed to believe in a government that was not driven by morality, but more by practicality. In, The Prince, Machiavelli stresses that the moral fibers of government should not be so soft. Like St. Augustine, his work went on to become one of the most famous books ever written about politics. Throughout the two works there are some similarities and differences regarding politics, however it their
Alzheimer’s disease is named after a German doctor, Dr. Alois Alzheimer. In 1906, Dr. Alzheimer became aware of changes in the brain tissue of a woman who had died of an unusual mental illness. Dr. Alzheimer found irregular clusters and tangled bundles of fibers. Today, these plaques and tangles in the brain are considered signs of Alzheimer’s (Shenk 12-14). Scientists have also found other brain changes in people with Alzheimer’s. Nerve cells die in areas of the brain that are vital to memory and other mental
When asbestos is handled, its tiny fibers float through the air and enter the body. When inhaled, these fibers lodge in the lungs and stay there, eventually causing lung cancer. Asbestos exposure has also been associated with stomach cancer, laryngitis, immune system suppression, enlargement of the heart and pleural abnormalities
Kevlar Aramid Fiber is a synthetic (man-made) material known as a Polymer. A polymer is a chain that is made up of many similar molecular groups, better known as ‘monomers’ that are bonded together. ‘Monomers’ are made up of fourteen Carbon atoms, two Nitrogen atoms, two Oxygen atoms and ten Hydrogen atoms. A single Kevlar polymer chain could possibly have anywhere from one to five million monomers bonded together. A group of polymer chains can be organised together in a fiber. How the polymer
parts, and production of body heat. These muscles all consist of a mass of protein fibers grouped together, and most are of mesodermal origin. And almost all of the muscle fibers you will ever have or need were present at birth. Nearly half of your body mass is muscles, the largest and strongest being in the shoulders, upper arms, hips, and thighs. There are over five hundred muscles in the human body. Muscle fibers are basically classified according to their size and speed of contraction. There are
is a drug extracted from hemp, a plant from which coarse fibers are also obtained for the manufacture of cloth, cordage, and sacking. The development of marijuana in Colombia took place in the mid 1940s during the administration of President Mariano Ospina Perez. The government at this time imported various fibers producing species from different parts of the world in an attempt to improve the postwar textile industry. The imported fiber plant included cannabis sativa (hemp) from Asia, and jute
process in which society and culture convey the history of a particular country or region as the Caribbean. In order to fully grasp the intricacies and complexities of Caribbean one must scrutinize and in a sense deconstruct the social and cultural fibers of the Caribbean. The remnants of colonialism in the Caribbean have created a history manifested in the imagery of society and culture. History in the Caribbean can be unveiled in skin tones and rumbas. The history of the Caribbean lives in architecture
As retired people are enjoying their retirement life and spending their time with their children and grandchildren, they should give them a gift as a reminder to the grandchildren that they love them unconditionally. Designing clothes by their own hands is unique and creative to express their feelings to the recipient. Not only do they show love unconditionally to their grandchildren but they can design whatever they desire since most parents struggle to find cute and stylish clothing for their children
Ligaments are tough, non-stretchable fibers that hold bones together. Damage to cruciate ligaments, which crisscross the knee to give it stability, is one of the most common sports injuries. The “tear” occurs from changing direction rapidly, slowing down from running, or landing from a jump improperly. The A.C.L tear is one injury that worries athletes in all sports at all levels because of its devastating effects. People ages 15-25 that participate in basketball and other sports that require pivoting
referred to as muscle fibers, these fibers are skeletal muscle fibers, smooth muscle fibers and cardiac muscle fibers. The anatomy of a skeletal muscle fiber is formed during embryonic development. Skeletal muscle fibers arise from a hundred or more small mesodermal cells called myoblasts. The mature skeletal muscle fiber has a hundred or more nuclei. Once fusion occurs the skeletal muscle fiber will lose the ability to undergo cell division. This means that the number of muscle fibers is set before birth
