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
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
brain that control thought, memory, and language. It can only be diagnosed by a histopathologic examination, to check for the presence of tangles and plaques, which are primary causes of Alzheimer's. Neurofibrillary tangles are bundles of twisted fibers that accumulate in the cell bodies of neurons. Neuritic plaques are round or oval lesions consisting of an amyloid protein core surrounded by fragments of damaged neurons. These types of lesions occur in the cerebral cortex and hippocampus, the regions
polish to the needle, reducing friction. Once, when his wife called him to dinner, he wiped the liquid from his hands onto a piece of pony-fur cloth. When he returned to his workshop, he saw that the fibers on the cloth were now standing straight. He conceived that the fluid had actually straightened the fibers. In order to confirm his theory, he decided to apply some of the fluid to the hair of a neighbor's dog. The fluid straightened the dog's hair so much, that the neighbor, not recognizing his own
Testing the strength of plant fibers Objectives: To develop knowledge and understanding of the strength of plant fiber in a plant stem. To develop problem solving and experimental skills, for example, information is accurately processed, using calculations where appropriate, experimental procedures are planned, designed and evaluated properly, the use of microscopes, producing valid results and recording results. To develop techniques of measuring the size of plant fibers under microscope using stage
a soft, fluffy, naturally occurring fiber plant that can be processed into an array of materials and goods. Many, many things that we wear, sleep on, sleep under, walk on, or utilize in wound-care, etc., contain some percentage of cotton. It is a fiber that is used everyday, by everyone, in one way or another. It has qualities that have made it a choice crop for centuries around the world. Today though, cotton is being largely displaced by synthetic fibers that have qualities that exceed the natural
Though often extensive detail may be condemned as mere flowery language, in understanding Sir Gawain and the Green Knight one must make special emphasis on it. In color and imagery itself, the unknown author paints the very fibers of this work, allowing Sir Gawain to discern the nuances of ritualistic chivalry and truth. His quest after the Green Knight is as simple as ones quest toward himself. Through acute awareness of the physical world he encounters Gawain comes to an understanding of the world
There are currently 6.5 million handloom weavers in India. The presence of this enormous workforce, second only in size to that of agriculture, points to the continued importance of the sector to Indian society, despite the pressures of modernization and globalization. With low import level and additional 4.8 million power loom weavers spread throughout the country, Indian cotton cultivation and yarn spinning have both by necessity grown to be large industries. This shows the demand and requirement
to spinning units in bale form. Types of Ginning: There are following two types of ginning; a. Roller Ginning b. Saw Ginning a. Roller Ginning: It is used for long length fibers. b. Saw Ginning: It is used for short length fibers Spinning: Spinning is the process of converting fiber into yarn. Machines in Spinning: Basically, Spinning involves following machines; 1. Blow Room 2. Carding
4.3. ACRYLIC SHEETS Acrylic is additionally celebrated by the trade names Lucite and Plexiglas. sold principally as a transparent glazing sheet, it should be worked properly to avoid cracking and breaking. Acrylic feels like glass, however, has 10-20 times the impact resistance for constant size. It’s way more able to survive stray footballs, bricks etc. Acrylic insulates higher than glass however but twins wall polycarbonate. It’s not suggested to be used because the sole layer of domestic glazing
Fiber is a threadlike material that can be found in a natural or manmade form. Natural fibers derive from various animals, plants and can even be produced by insects. These fibers have been in use since prehistoric times and are currently produced today. The most common natural fibers used are linen, wool, silk and cotton. They have been woven together to create fabrics for clothing and other items. A natural protein fiber, called wool, was discovered before 10,000 B.C.E. and woven into cloth by
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
