Site Plan | I. Neurons/nerve cells A neuron is a cell specialized to conduct electrochemical impulses called nerve impulses or action potentials. Neuron is the main cellular component of the nervous system‚ a specialized type of cell that integrates electrochemical activity of the other neurons that are connected to it and that propagates that integrated activity to other neurons. They are the basic information processing structures in the CNS.

allow cell phones to be sold without pre-market testing. The rationale‚ known as the “low power exclusion‚” distinguished cell phones from dangerous microwave ovens based on the amount of power used to push the microwaves. At that time‚ the only health effect seen from microwaves involved high power strong enough to heat human tissue. The pressure worked‚ and cell phones were exempted from any type of regulatory oversight‚ an exemption that continues today. An eager public grabbed up the cell phones

A tropical cyclone is a rapidly-rotating storm system characterized by a low-pressure center‚ strong winds‚ and a spiral arrangement of thunderstorms that produce heavy rain. Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy from the evaporation of water from the ocean surface‚ which ultimately recondenses into clouds and rain when moist air rises and cools to saturation. This energy source differs from that of mid-latitude cyclonic storms‚ such

of non-melanoma skin cancer are treated in more than 3.3 million people. Despite these staggering statistics‚ skin cancer does receive nearly as much attention as other more talked-about forms of cancer. Skin cancer is just as serious as any other type cancer and should be taken seriously by the people of the United States. Many people die from skin cancer‚ and it attacks people of all ages‚ therefore people should be more aware of skin cancer and realize how serious it is. Skin cancer occurs when

him or her having Sickle Cell Disease. What this is is it’s a disease that is genetically inherited and it involves the red blood cells. Mutations in the HBB gene cause this disease. This disease is inherited in an autosomal recessive pattern‚ which means both copies of the gene in each cell will have mutations. The parents of offspring with an autosomal recessive gene each carry one copy of the mutated gene. The blood cells form an abnormal crescent shape (normal cells are in a disk form). The
