a.
To determine: Whether glucagon secretion in response to declining blood glucose is positive or negative feedback.
Introduction: Glucagon is a peptide hormone released by the pancreas in response to the blood glucose level. The change in the blood glucose level of the human body is maintained by glucagon.
b.
To determine: Whether increasing milk release and secretion in response to baby’s suckling is positive or negative feedback.
Introduction: Oxytocin hormone is mainly responsible for the ejection of milk after parturition.
c.
To determine: Whether urgency in emptying one’s urinary bladder is positive or negative feedback.
Introduction: Micturition reflex is mainly responsible for urination in humans. The urination is controlled voluntarily in case of adults.
d.
To determine: Whether sweating in a response to rising body temperature is positive or negative feedback.
Introduction: Sweating helps the body to maintain the internal temperature of humans in summer.

- The hypothalamus contains the feeding and thirst control center. A. True B. Falsearrow_forwardHow do the functions of the HPA axis compare to those of the sympathetic nervous system?A. The sympathetic nervous system readies the body for brief, vigorous action, and the HPA axis controls digestion and other vegetative activities.B. The sympathetic nervous system activates the brain, and the HPA axis activates the rest of the body.C. The sympathetic nervous system readies the body for brief, vigorous action, and the HPA axis prepares the body for prolonged coping with a persistent stressor.D. The sympathetic nervous system is active during a stressful situation, and the HPA axis becomes active at the end of the stressful situation.arrow_forwardWhich of the following responses is an effector activated by the hypothalamus when the body temperature is lower than the set point? a. skeletal muscles contract b. sweat glands initiate sweating c. skin blood vessels dilate d. move to a warmer location or put on a sweaterarrow_forward

- A nursing mother who has an alcoholic drink will secrete alcohol into her milk for two to three hours afterward. Alcohol also decreases her oxytocin production.
