n response to an increase in body temperature, which ONE of the following acts as an effector in the thermoregulatory negative feedback system? sensory nerve fibers sweat glands hypothalamus thermoreceptors1 points

Explain the role of the adrenal glands in responding to a decrease in body temperature. [5 marks]

Which of the following is the best description of the homeostatic mechanism of negative feedback?Adjustment made by the body to return itself to normal after detecting a changeAdjustment made by the body to decrease the rate of metabolismAdjustment made by the body to increase the rate of metabolismThe negative thoughts that occur when the body is in fight or flight mode2What is the role of the pituitary gland in regulating metabolic rate? It detects the levels of glucose in the bloodIt releases thyroxineIt releases thyroid stimulating hormoneIt controls the amount of oxygen entering the body3What happens when the amount of thyroid stimulating hormone released from the pituitary gland increases? More thyroxine is released from the thyroid, metabolic rate increasesLess thyroxine is released from the thyroid, metabolic rate decreasesMore thyroxine is released from the thyroid, metabolic rate decreasesLess thyroxine is released from the thyroid, metabolic rate increases4Which gland is located at the top of your kidneys?Adrenal glandsPituitary glandSweat glandThyroid gland5Which of the following is not a ‘flight or fight’ response caused by the release of adrenalin? Increased heart rate and breathingBreakdown of glycogen reserves to produce glucoseBlood redirected from skeletal muscles to digestive systemDilation of pupils6Which of the following hormones is not controlled by a negative feedback mechanism?AdrenalinADHInsulinThyroxine

Which of the following is an example of an ‘effector’ for negative feedback in response to cold temperature? Which of the following is an example of an ‘effector’ for negative feedback in response to cold temperature? Hypothalamus integrating information Sweat glands producing sweat Thermoreceptors Skeletal muscles shivering
