Biological Mechanisms of Hunger
What Causes Hunger: The Biological Mechanisms of Hunger
The biological mechanisms that trigger hunger are rather complex. In that regard, several theories have been proposed in an attempt to explain hunger and the biological mechanisms that control it. It is therefore important to note that the feeling of hunger has no single source. Indeed, as Pastorino and Doyle-Portillo (2012) point out; although the stomach plays a role in the initiation of hunger, it is not the only source of the same.
The liver according to Pastorino and Doyle-Portillo (2012) plays an important part in the regulation of hunger. This it accomplishes by closely monitoring not on the levels of glucose but also the levels of glycogen in the body. In basic terms, glucose (a form of sugar) is burnt by our bodies for energy. On the other hand, glycogen according to Pastorino and Doyle-Portillo (2012) "is the form of starch that we store along with fatty acids." Glucose deemed by the body to be in excess of the required amount is converted into glycogen and stored for future utilization...
Theoretical Perspective of the Biological Approach to Personality Psychology Personality is defined as a person's exceptional deviation on the general evolutionary design for human temperament. A personality trait refers to a durable disposition to act in a certain manner in different situations. Personality traits represent some of the most significant sets of individual disparities in organizations. It is the comparatively set of psychological characteristics that differentiates one person from another. People
Neuroscience and Human Development One of the most noticeable aspects of human beings involves the changes in shape, size, form, and function of the individual from a newly formed fetus to a fully grown adult. As the single most successful organism on Earth, human beings have developed, through millions of years of evolutionary adaptations, integrated yet malleable systems involving biological, physiological, emotional and intellectual components. This paper will review some of
Jesus' Teachings, Prayer, & Christian Life "He (Jesus) Took the Bread. Giving Thanks Broke it. And gave it to his Disciples, saying, 'This is my Body, which is given to you.'" At Elevation time, during Catholic Mass, the priest establishes a mandate for Christian Living. Historically, at the Last Supper, Christ used bread and wine as a supreme metaphor for the rest of our lives. Jesus was in turmoil. He was
R Harris "believes that parent do not shape their child's personality or character" (Lee, 2003) rather, it is the child's peers who hold more influence on the child. According to Harris, children do not use all the information they have learned from their parents. In general, children behave in the manner which they have learned from people in their social group. According to Haimowitz, family environment does not contribute much to
(Harvard School of Public Health, 2013, p.1) Energy expenditure is decreased due to sleep deprivation because there is a decrease in physical activity as well as the body temperature being lowered. (Harvard School of Public Health, 2013, p.1) Summary of Literature The literature reviewed in this study has informed the study that children who sleep less hours each night are at a higher risk of becoming obese than children who sleep more
" (Dietz, 1998). Obese children are often taller than their non-overweight peers, and are apt to be viewed as more mature. This is an inappropriate expectation that may result in adverse effects on their socialization. (Dietz, 1998). Overweight children and adolescents report negative assumptions made about them by others, including being inactive or lazy, being strong or tougher than others, not having feelings and being unclean. (American Obesity Association, 2000). This
