Storyboard Text

  • Today I'm going to be teaching you about negative feedback and what it does to our bodies.
  • First if you are outside and it is very hot, you will begin to start sweating and continuously sweating until your body is back to a stable state.
  • The receptors are temperature controlled cells in the skin and brain that receive a signal that the body is too hot and unstable. So, the afferent neurons carry the impulse to the brain to acknowledge the change.
  • Then the control center which is the thermoregulatory in the brain receives the signal of being unstable and then sends a signal to the effector.
  • The effector is what fixes the body to be stable again. So when the body is hot the effector will get the body to sweat to release heat. 
  • Once the body is in a stable homeostasis again, the body will stop sweating. So, negative feedback is when the variables like heat have a counter response where everything comes back to normal.
