An Example of a Receptor in a Negative Feedback Loop

Question

An example of a receptor in a negative feedback loop controlling body temperature would be
A) temperature sensors on the skin that detect a stimulus.
B) sweat glands that increase secretion.
C) regulatory centers that send commands to an effector.
D) effectors that cause blood vessels to dilate.
E) sweat glands that act like effectors.

Accepted Answer

Temperature sensors on the skin detect a stimulus and send signals to the regulatory centers in the brain, which then activate effectors such as sweat glands or blood vessels to restore body temperature to its set point. This is an example of a negative feedback loop as it works to counteract any deviation from the set point temperature.
