It is very much essential for a content living. A biological mechanism that motivates events associated with pleasure is known as the reward. Pleasure can lead to good effects like health and productivity, and cognition and, at the same time cause negative behaviors like the addiction. Pleasure depends on the reward circuitry which is nothing but limbic activity. Dopaminergic signaling is the most important neurotransmitter system involved in pleasure. While natural rewarding activities are crucial for appetite motivation and survival of any individual, artificial pleasurable activities have detrimental effects not only on the health of the individual but also on the family and society. Drugs and alcohol are the most common sources of artificial pleasurable activities. These substances cause-the effect by acting on the various neurotransmitter systems of the brain. Persistent intake of these substances results in addiction. People who are addicted to a particular substance cannot quit taking that substance on their own. Hence it can be said that addiction is a type of illness and needs treatment. There are many causes for the development of addictive behavior. While the drug itself leads to drug-seeking behavior, research has shown that many changes in the brain can be the main contributing factors for this condition. According to the current model that explains addiction behavior, addiction begins in the brain through pleasure and reward circuits involving dopamine. ...Download file to see next pagesRead More

...? Causes of diabetes Research proposal Insert Grade Introduction Indeed, diabetes has become a major global crisis due to its effects and scale of prevalence. It has led to an unproductive society that directly impacts its growth. Its physiological aspect is that many studies show that it majorly arises from the lifestyles that people lead (Dijk, 2012). The outcome of diabetes is profound in that it also affects the physiological well-being of a person. Dijk (2012) states that a lot of people suffer from type 2 diabetes which has been found to be on the rise with the rise in obesity. Study also shows that with its faster economic growth, Asia has become the epicenter of the disease. According to Struijs...

... of the gastrointestinal function. (15) Gastrointestinal function is regulated by the sympathic and parasympathic autonomous nervous system. The parasympathetic innervation of the gastrointestinal tract is provided by the vagal nerve (upper part of abdominal viscera) and the pelvic nerve (lower segments of colon and rectum). The sympathetic innervation is supplied by the branches of the paravertebral chain, prevertebral coeliacomesenteric and caudal mesenteric ganglia. Parasympathetic stimuli activate the peristalsis and secretion whereas the sympathetic stimuli produce opposite effect. References: Guyton, A.C. & Hall, J.E. 2000.

...The Physiology of Addictive behaviour Research has confirmed that the cause of addictive behaviour is not a single gene but a combination of several genetic factors. It is also interesting to know that addictive behavior can be present even before the drug usage habit is formed. The question that now arises is whether addictive behaviour is the result of host of genetic factors or is it the response to environmental factors. Another factor to be considered also is why the source of the behaviour not revealed during its prognosis. “Once an individual begins using psychotropic substances such as cocaine or heroin, measurable changes in brain chemistry and...

...Skeletal System Essay DESCRIBE THE DEVELOPMENT AND GROWTH OF BONES Ossification or osteogenesis begins towards the end of 8th week of gestation. All bones begin as mesenchymal condensations during the embryonic period. The fibrous condensations ossify into the membrane or dermal bones and the cellular condensations ossify in to hyaline cartilages (Gardner, 856-862). Thus, the skeletal pattern is formed in cartilage and connective tissue membranes. From here, bone development continues throughout adulthood. The 3 cell types involved in the development, growth and remodeling of bones are osteoblasts, osteocytes and osteoclasts. While osteoblasts are bone-forming cells, osteocytes are mature bone cells and osteoclasts break down... System Essay...

...High Altitude Training High altitude training is a method that has gone through extensive research over the past years. It is an interesting trainingprocedure that is being adopted by Olympic and professional athletes worldwide. Many professional athletes, today, include a section of high altitude training in their routines. They train at higher altitudes to prepare for lower altitude oxygen level. The idea behind this form of training is that if an athlete can get used to the tough environment that is present at higher altitudes, he or she would have experience a higher level of endurance when traveling to lower altitudes. The reason is that at higher altitudes, there is lesser amount of oxygen for the body and muscles... Altitude Training...

Submission: Physiology behind Pulse Rate, Temperature, Respiration and Control Mechanisms of Peripheral Heat has to be related to the skin’s surface in order to maintain a constant body temperature. After the evaporation, the cooled blood returns to the core of the body this regulating the temperature. Blood flowing through the dermis is regulated when one’s body heat is stable depending on the changes in ambient temperature. This is to ensure that differences in temperature between the environment and the skin remain constant thus preventing heat loss and attaining a constant temperature (Yagiela,...
