This contraction cycle is repeated as long as free calcium is available to bind the troponin and ATP is available to provide the energy. The signal to stop contraction is the absence of the nerve impulse at the neuromuscular junction. When this occurs, an energy requiring calcium pump located within the sarcoplasmic reticulum begins to move the calcium back into the sarcoplasmic reticulum. This removal o...

Human Cloning Foundation Spinal Cord
1,306 wordsWhen one thinks of cloning, what comes to mind? Movies such as Multiplicity can give the layperson a much-distorted image of cloning. In this particular movie, actor Michael Keaton plays a father who cannot handle his crazily busy lifestyle. In an effort to be the perfect father, husband and employee, he has himself cloned easily at a nearby medical center. The three clones each have their own personality: one is sarcastic and bitter, one is sweet and sensitive and one is a half-wit but all are ...

Beginning Of The End Polio Vaccine
730 wordsBefore the development of the Salk and Sabin vaccines, polio was a serious infection that affected the central nervous system; however with proper vaccinations it can be eradicated in the United States today. There are different kinds of polio. They include spinal polio, non-paralytic form, and paralytic polio. Spinal polio is the most common form that occurs when polio viruses attack nerve cells and control the muscles of the legs, arms, trunk, diaphragm, abdomen, and pelvis. Stiffness in the n...

Spina Bifida Spinal Cord
489 wordsSpina Bifida is a Latin term meaning split spine. It is the name given to a group of birth defects, which interfere with the development of the central nervous system: the brain, the spinal cord and the nerve tissues. It results from the failure of the spine to close properly during the first month of pregnancy. In severe cases, the spinal cord protrudes through the back and may be covered by skin or a thin membrane. Surgery to close a newborn's back is generally performed within 24 hours after ...

Rabies is easily associated with rage. When people think of rabies, they usually think of a mad raccoon or dog, foaming at the mouth and running around crazy; dying soon after. The thought of going crazy is a pretty reasonable guess for how rabies torments its victims. The virus enters through a bite or transfer of infected saliva and...

Down Syndrome And Spina Bifida Cause Effects Treatment
635 wordsMany individuals are born with defects due to genetic factors. Some such defects occur because the child inherits a defective gene, or genes from the parents. Others are caused through mutations- spontaneous changes that occur to a gene or chromosome. Environmental factors affecting the foetus during the uterine development may also cause defects. If, during pregnancy, a woman smokes, consumes alcohol or other drugs, or suffers dietary deficiencies, the developing foetus may be adversely affecte...

Millions Of People Defective Genes
847 wordsIn the past couple years, the topic of genetic cloning has been under heated debate by people all over the world. This debate began when Scottish scientists cloned a sheep named Dolly. The event made headlines around the world and was seen as the beginning of the end for the human race, as we were dawning on a new era in science, one that was to be filled with immoral acts that were seen as scientifically impossible a few years ago.

The disease has always had a hold on the public imagination and has been looked upon with horror. It evokes visions of raging victims, bound and howling, or asphyxiated between two mattresses (Duclaux). The treatments applied to victims were as horrible as the supposed symptoms: this included cauterizing the bite wounds ...
