Answer to Question #334593 in Human Anatomy and Physiology for cornnnfrogeuu

Question

1.What is the stimulus in the feedback loop below?

2.What is the control center in the feedback loop below?

3.Mention 2 effector organs that process so that the body could return to a set point?

When body temperature drops, the hypothalamus initiates several physiological responses to increase heat production and conserve heat: Narrowing of surface blood vessels (vasoconstriction) decreases the flow of heat to the skin; shivering commences, increasing production of heat by the muscles; Adrenal glands secrete stimulatory hormones such as norepinephrine and epinephrine to increase metabolic rates and hence heat production. These effects cause body temperature to increase. When it returns to normal, the hypothalamus is no longer stimulated, and these effects cease.

(feedback mechanism)

Answer 1

1.The stimulus is when the body temperature drops below accepted( normal) line.

2.The control center is the hypothalamus.

3.Muscles and Adrenal gland.
