unpleasant stress inducing event that happened to me lately‚ the bereavement of my mother and the last exams that I have to deal with. The malfunction of HPA axis management can result to pathological diseases (Guillians & Edwards‚ 2010). The hypothalamus particularly Hypothalamic-Pituitary-Adrenal (HPA) Axis and the sympathetic nervous system (SNS) is a part of the brain that spring into action in times of potential danger or an alteration in homeostasis due to stressor which triggers hormones

"Explain the concept of homeostasis with reference to the control of heart rate‚ breathing rate‚ body temperature and blood glucose levels" P5 Homeostasis is where the body keeps a constant internal environment. This involves all the metabolic processes taking place In the body as well as the blood‚ tissue fluid and all the contents in the body ’s cells. There are a range of variables from heart rate to the blood glucose levels that the body will take into account. Negative feedback will occur

called the posterior pituitary. The brain controls the activity of the pituitary gland in two ways. Releasing hormones from the hypothalamus control the secretions of the anterior pituitary and are carried in the bloodstream by hypophyseal portal veins. The posterior pituitary releases hormones into the bloodstream in response to nerve impulses from the hypothalamus. Anterior Pituitary Gland: The anterior pituitary consists mostly of epithelial tissue arranged around blood vessels

The kidneys are a pair of fist-sized organs located outside the peritoneal cavity on each side of the spine. The kidney is a highly specialized organ that maintains the internal environment of the body by selectively excreting or retaining various substances according to specific body needs.

(Taylor‚ 2012). Secondary appraisals is the initiation of the person’s response and coping strategies to the stress. Stress can take a toll on a person’s body. The cerebral cortex is responsible for labeling an event threatening or harmful. The hypothalamus gets information from the cerebral cortex to initiate the flight or fight response also known as sympathetic nervous system arousal. This arousal stimulates the medulla of the adrenal glands which then secrets epinephrine and norepinephrine (Taylor
