Adrenal cortex

and some neurons inhibit, stimulate or control heart rate by causing constriction which also controls the blood pressure. The cardiovascular centre receives input responses from the brain via sensory receptors. The impulse travels from the cerebral cortex and hypothalamus to affect the cardiovascular centre. Vasodilation of blood vessels…

The purpose of the homeostatic system is to maintain a stable environment despite fluctuations in the external environment, homeostasis meaning ‘same state’. Glucose homeostasis refers to maintaining blood glucose levels in the human body. Glucose is one of the most important energy sources. For various tissues in the body, such as the brain, glucose is the only substance used. It is important that there is a continuous supply of glucose for this reason. For homeostasis of the internal…

Stressed lifestyle and personality are some of the psychological factors that influence health and behaviour in our lives. However, our response to stressors determines our ability to control and manage or develop illness out of the stress. “Stress is experienced when a person’s perceived environmental, social, and physical demands exceed their perceived ability to cope, particularly when these demands are seen as endangering the person’s well-being in some way” (Cardwell & Flanagan, 2012).…

steroids are made up of androgens and estrogens. Androgens are the male hormones the body produces and estrogens are the female hormones the body produces. Corticosteroids are hormones that include cortisone and cortisol. Cortisol is secreted by the adrenal cortex and it helps with the maintenance…

Today in several cities around the country there is a place within the city that is producing lower health outcomes. It is very common to find neighborhoods within much larger cities that have higher levels of poverty than the city it surrounds. In West Side of Syracuse, New York there are many environmental, physical, social, and service problems that contribute to the quality of the neighborhood. In a city of almost 145,000 people, there are many things that can be fixed such as poverty.…

a large number of studies have been conducted to reveal further factors that impair memory performance. Previous physiological perspectives on memory have hypothesized that stress has an impact on memory as it activates the hypothalamic–pituitary–adrenal (HPA) pathway, resulting in the secretion of corticotrophin-releasing hormone and altering the brain’s chemical composition. This in turn would make access to stored information during a stressful situation harder than in normal conditions. The…

After reviewing the case of 28-year-old Owen, it is evident that he suffers from an anxiety disorder due to the simple fact that he has feelings of extreme nervousness that are interfering with his job. However, this is not his only symptom of anxiety he shows. Anxiety is usually not the only mental disorder one encounters at a time and he does show symptoms of other mental disorders as well. After reading Owen’s case the generalized anxiety disorder (GAD) stands out. GAD is a serious and common…

These individuals are serving our country and risking it to defend an American Dream. Over the years served, they are asked to fight on seas in wars and secret battles for the right to come home. These deployments or trainings can last any given period time in a year. This would cause a change in their personal, family, professional, and any other level that affects daily function to return back to a normal live. One of these biggest issues that an active duty service member, veteran or…

Aggressive Behaviour: Nature, Nurture, or both In the text, Comparative Psychology, aggressive behaviour is defined as a potentially harmful interaction between members of a species. Researchers have been examining the relative influence of nature and nurture to investigate the origin of aggressive behaviour. Literature reviews have assessed the genetic endowment on shaping aggressive behaviour (nature) or environmental influences on shaping aggressive behaviour (nurture). The motive of this…

This lab included various experiments that demonstrated how renal system responses and reacts when subjects consuming different types of fluids. Respective fluid volumes are based on each subject’s body mass. Based on each subject’s body mass, after converted from pounds to kilograms, every subjects has different volume and fluids for ingestion. For the control subject, she ingested no fluid throughout entire lab which represented the conditions of normal fluid. For the hypotonic subjects, she…
