if it is a wave. On contrast‚ along myelinated axons‚ the signals are “jumping” due to the process called saltatorary conduction. An area of which myelinated axons are unmyelinated is labeled as the nodes of ranvier. Considering myelin act as an insulator‚ myelinated fibers aren’t capable to conduct impulses. Therefore along myelinated axons‚ action potentials can only take place on the nodes and thus‚ making it “jump” from nodes to nodes. By forcing the electric charge to “jump”‚ the conduction on

ABSTRACT: The overall concept of nano-technology is that working with smaller particles of nano size (ie.‚10-9). The discovery of Bucky ball created a new revolutionary in the field of nanotechnology. Bucky ball is a concept in nanotechnology which has created a great impact in various fiels like electronics‚ medical‚ drug delivery‚ strong devices etc..‚ Bucky ball is a concept which is still in a developing stage. There are so many effective things yet to be uncovered. In this article‚ we have

Jack London “To Build a Fire” Man was created intelligent and as a result he was to assert dominance over all animals; both on land and in the sea. This intelligence has been used by man to make advancements in various fields such as medicine‚ technology and many more. This creativity has seen man improve his way of life to an extent where he has come to believe he can handle anything thrown at him by Mother Nature. Animals on the other hand‚ were created with instinct which man has been able

protective myelin coating‚ and destruction of brain cells. Krabbe disease is one of a group of genetic disorders called the leukodystrophies. These disorders impair the growth or development of the myelin sheath‚ the fatty covering that acts as an insulator around nerve fibers‚ and cause severe deterioration of mental and motor skills. Myelin‚ which lends its color to the “white matter” of the brain‚ is a complex substance made up of at least 10 different enzymes. Each of the leukodystrophies affects

Lesson Plan: Electric Circuits (~130 minutes) Concepts 1. Electricity is the flow of electric charge (electrons). 2. Electric Charge is a property of subatomic particles. 3. Current is the movement of electric charge. 4. Voltage is the electric potential that exists to move a charge. 5. Power is the rate at which electric energy is flowing in a circuit. 6. Ohm’s Law: Power = Voltage x Current. 7. Resistance is a physical property that quantifies how well a charge

The statue of Liberty first arrived in America in 1886 and took up permanent residency on Bedloe’s island in New York Harbor. The statue weighs in at 280 tons and is visible for more than 42 miles on a clear day. The statue of Liberty is without a doubt‚ among the most monumental figures in American history. The Statue of Liberty is made of an aluminum scaffolding‚ an iron framework and metal skin made from copper. Originally‚ she was to be made of bronze‚ but weight problems required a switch to

The Poisoning of Our Ozone Layer The poisoning of the Earth’s ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozone’s depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is not just one effect from the poisoning of the ozone‚ but instead multiple ramifications from diseases to death. The
