Insert Table Chart Text Shape Media Commant 87. What are the roles for stress hormones (glucocorticoids, epinephrine, and CRH)? How does the GAS (general adaptation syndrome) system work? Relate it to wound healing? What processes does it interfere with? 88. Endocrine pancreas. What are the effects of insulin and glucagon on anabolism and catabolism. Interpret when insulin vs. glucagon are high/ low during the day (related to eating/ fasting). Know they are antagonistic hormones. 89. What is diabetes mellitus? What is the cause of Type I vs. Type I1? Why would someone with diabetes get ketoacidasis if they are eating enough carbohydrate? What are effects of high blood glucose in diabetes? Also put some of these symptoms in terms of osmosis. 90. Melatonin is the main hormone secreted by the pineal gland. What are the major roles of melatonin? 2,032 words FI F2 FSExplanation / Answer
87.
Role of CRH (Corticotropin-releasing Hormone): It stimulates anterior pituitary to release adrenocorticotropic hormone which turn, act on adrenal cortex to liberate adrenocorticosteriods.
Role of Glucocorticoids: It promotes gluconeogenesis, suppression of inflammatory response
Role of epinephrine: It increase glycogenolysis, gluconeogenesis and decrease glycogenesis
i. GAS (General adaption Syndrome): it is introduced by Hans selye. Defined as a nonspecific general response to noxious stimuli
It is 3 stages:
a. Alarm
b. Resistance
c. Exhaustion
ii. It stimulates marcophages , immune cells to heal wounds
iii. GAS interfers immunity
88. Insulin - Hypoglycemic effect:
i. Glucose up take increased
ii. glycosis increase
iii. HMP shunt increase
iv. gluconeogenesis decrease
v. glycogenolysis decrease
Glucagon:
i. glucoenogenesis increase
ii. glycogenolysis increase
Exercise and eating a protein rich meal decrease blood glucose level which stimulates glucagon. When blood glucose levels increase, insulin is secreted to regulate it in the blood.
90.
Major of melatonin: The presence of moles on the body represents a localized severe hyperpigmentation due to hyperactivity of melanocytes.
2. Albinism is an inborn error with generalized lack of melanin synthesis
