Question

some of the nerve endings in the skin are sensitive to changes in temperature and are part of a negative feedback mechanism regulating body temperature. these nerve endings represent a(n) __________ in the negative feedback mechanism.
a) effector
b) receptor
c) homeostatic balance or \ideal\ value
d) control center

Explanation:

In a negative - feedback mechanism regulating body temperature, nerve endings in the skin that are sensitive to temperature changes detect the stimuli. Receptors are structures that detect changes in the environment. Effectors produce a response, the homeostatic balance is the stable state to be maintained, and the control center processes the information from receptors. These nerve endings are receptors.

Answer:

B. receptor
