Advanced Anatomy and Physiology October 2, 2016 Hypertension secondary to Pheochromocytoma Definition: Pheochromacytomas are neuroendocrine tumors of the adrenal medulla (and occasionally elsewhere) that can result in hypertension secondary to the hypersecretion of the catecholamines epinephrine and/or norepinephrine. This can be continuous or episodic and this release subsequently affects blood pressure by raising it as part of the body’s fight or flight response. According to our…

ALS is a multi-factorial neurodegenerative disease that affects the upper and lower motor neurons of the spinal cord. It is found in both familial and sporadic forms. Familial ALS is recognized by mutant SOD1 which fails to convert reactive oxygen species to hydrogen peroxide and/or water; however, studies have shown the presence of SOD1 aggregates in sporadic forms as well (Redler and Dokholyan, 2012). This is due to the ability of wild-type SOD1 to become toxic due to oxidative stresses in the…

In the 1930s, Dr. Ingle and his team set up a series of experiments in order to better understand the working relationship between the pituitary and adrenal glands. They hypothesized that the release of cortin from the adrenal cortex was regulated by the anterior lobe of the pituitary. At the time, it was established that treating animals with high doses of cortin caused the adrenal cortex to regress, and that the same effect was also observed when mice were hypophysectomized. Dr. Ingle…

The Effect of Stress on the Brain Stress is predominantly a bodily response to an environmental stimulus. Stress responses are an important warning system to indicate approaching danger. For instance, the stress of physical pain is a warning for tissue damage, the stress of hunger warns of impending low blood sugar levels, the emotional stress of loneliness warns of potential vulnerability from predators and a lack of group protection (*) There are many different sources of stress,…

Dermatology Clinic: Questions and Answers Case 1 1. What is your diagnosis? This patient exhibits signs and symptoms of iatrogenic Cushing syndrome with steroid acne due to corticosteroid withdrawal. 2. What factors may have contributed to the disease? The chronic treatment with high doses of prednisone contributed to the patient’s Cushing syndrome. However, steroid withdrawal may have caused her recent skin flare around her trunk and extremities. 3. What is the treatment of choice for this…

the release of cortisol and DHEA. Cortisol is a hormone that is released and notifies that brain to engage in flight or fight and DHEA is a cell repairing hormone correlated with cortisol (Hucklebridge, Hussain, Evans, & Clow, 2005). DHEA is released to combat the negative impact that cortisol has on tissue (Carlson, Speca, Patel, & Goodsey, 2004). The emotional stress from experiencing racial…

Happiness Leads to Less Stress It’s safe to assume that more stress leads to less happiness, but is it safe to assume that happiness leads to less stress? Questions like these are those that social psychologists ask everyday. Social psychology originates from the broader study of psychology that focuses on human behavior in social settings (McLeod, 2007). There are a variety of research methods that social psychologist can employ such as, correlational, observational, and experimental. The…

The results of the experiment showed a significant change in plasma glucose and serum cortisol concentrations of the sheep that were administered insulin which validates the hypothesis of the experiment. Glucose does not readily penetrate cell membranes as cell membranes are composed of phospholipids and glucose is hydrophilic and lipophobic due to the hydroxyl groups (Klein, 2013). Insulin, the major hormone that controls plasma glucose concentrations, increases the permeability of the liver,…
