The possibilities of space exploration are unknown, but with the advancements that are to come interstellar travel is one of those possibilities. The propulsion systems these spacecraft are to be far more advanced that of what is in current use. As stated earlier if nuclear fusion is to be incorporated into propulsion systems the distance in which mankind is to travel throughout the universe would increase greatly. Instead of being able to reach Mars in two to three months, it could take only…

esophagus is the first place peristalsis occurs. Peristalsis is the rhythmic contractions of smooth muscle in the esophagus and the intestines that aids in the progression of food through the tract. Peristalsis is controlled by the parasympathetic nervous system. When digestion begins, signals are sent to and from the brain that controls movement and the release of enzymes or hormones. There are two types of nerves that control digestion: extrinsic and intrinsic. Extrinsic nerves control…

As a matter of fact, there is no link between vaccines and autism. There is a strong evidence between MMR and autism which states that autism won’t occur at all after a vaccine shot. Several researchers have failed to find the relationship between MMR and autism. The evidence which they found is that the vaccine or thimerosal aren’t the substances…

symptomology. Other neural networks affected include the insular and cingular cortexes that can affect how intensely people feel emotions (Etkin, Egner, Kalisch ,2011).
