Some of the nerve endings in the skin are sensitive to changes in temperature. They are part of a negative feedback mechanism regulating body temperature. These nerve endings represent a(n) __________in the negative feedback mechanism.
A) control center
B) homeostatic balance or "ideal" value
C) receptor
D) effector

Quizplus · Accepted Answer

The sensitive nerve endings in the skin that detect changes in temperature are receptors in the negative feedback mechanism. They detect changes in temperature and send signals to the control center (the hypothalamus in the brain) which then activates the appropriate effectors (such as sweat glands or blood vessels dilating or constricting) to maintain homeostasis. The homeostatic balance or "ideal" value is not represented by the nerve endings, but rather by the set point established by the control center.
