A brain is the central part of nerves system in our bodies which is responsible for the collection, analysis information and manages and controls most of the members in the body. The brain is made up of millions of nerve cells when the baby is born. It goes through many physical changes in human’s lives. Here we focus on the major of these physical changes which are pruning, myelination and delegation, so these changes affected the brain’s abilities through the stages of human life, infant…
The five distinct senses act independently; However, they also team up to empower the mind to have a more useful understanding of its surroundings.

Smelt a scent and it brought back a certain place or memory? Every moment of the day at least one of our senses is working hard; replenishing the Brain with new information on how to be safe, how to…
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…
the CDC (2013), “Vaccines help develop immunity by imitating an infection. This type of infection, however, does not cause illness. The infection does cause the immune system to produce T-lymphocytes and antibodies.” The idea is to give your body a warmup fight with the infection so that if the real thing ever hit, your immune system already knew how to fight it off. Over the years, vaccines have been incorporated into society with most children…
prevent the spread of diseases and infections to others. During our health literacy research we found that the Immunize for Good website included a list of people who can benefits from vaccinations. These benefits include helping those with weak immune systems and pregnant women just to name a few. There a tons of diseases that run rapid around the world, but are uncommon in the United States because of vaccinations. Recently in 2014 the United States experienced a measles outbreak which came…
Indeed, many people assume that vaccines may cause autism and other disorders while vaccines can fight of the infections in the best possible way. 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). The mood instability seen in BPD often leads to depression in where neurotransmitter systems are dis-regulated affecting the output of serotonin, norepinephrine, and dopamine (Siever, Davis,…
Many dreadful and deadly diseases have all but been eliminated in modern society due to vaccinations. However, recently some of these diseases seem to be on the rise again which is probably due to more parents opting out of having their children vaccinated. Over the past decade, much controversy has arisen concerning whether or not to have children vaccinated. Most of the arguments against vaccination are simply based on fear and not on scientific evidence. Parents express fear of their child…
developing his ideas? Tragedy of the commons can be defined as an economic theory within a shared resource system where individual users act independently according to their own self-interest contrary to the common good of society by depleting or spoiling that resource.
