- Elevated levels of cortisol have been shown to reduce areas of the hippocampus in the brain resulting in short term memory loss in older adults.(source: Sonia J. Lupien et al. Nature Neuroscience 1, 69–73 [1998])Exposure to long-term stress results in elevated levels of cortisol in adults. Over time, cortisol may have detrimental effects on your health.Determine the effect below that is NOT a result of long-term stress.there are two biological stress pathways by which stressors produce arousal throughout the brain and body. Which are they?Which of the following hormones are NOT released in response to releasing hormones secreted by the hypothalamus? a. FSH and LH b. ADH and prostaglandin c. Oxytocin and thyroxine d. hGH and calcitonin
- A scientist studying pain processing in a mouse model administers a drug that inhibits proteolytic processing of proopiomelanocortin (POMC) in the pituitary. An increased response to painful stimuli is noted in the treated animals compared to controls. The effect of the drug is due to a lack of effective levels of Group of answer choices β-endorphin ACTH Growth Hormone α-melanocyte-stimulating hormone (α-MSH)If a patient is hypoglycemic, which of the following physiological processes will occur in an attempt to correct this situation? A). ACTH will be released by the posterior pituitary gland to stimulate the adrenal gland, B).glucocorticoid will be released by the adrenal cortex and increase serum glucose levels, C). mineralcorticoids will be released by the adrenal cortex and potentiate catecholamine effects, D). epinephrine will be secreted by the adrenal cortex in an attempt to increase blood serum glucose levels.Researchers have discovered several neurological issues in the brains of patients with affective (mood) disorders. Which of the following neurological anomalies is found in bipolar patients during a manic episode, but NOT in patients experiencing depression? A) Reduced brain tissue in prefrontal areas and hippocampus. B) Increased metabolic activity in part of the prefrontal cortex. C) Enlargement of the amygdala and hypothalamus, leading to greater stress responses and higher cortisol levels. D) Reductions in overall brain activity, and especially in prefrontal regions and other circuits that regulate emotions.
