negative feedback to control glucose levels

If blood glucose levels are too high, insulin is released by the pancreas to signal cells to take in glucose for energy or storage.
If blood glucose levels are too low, glucagon is released by the pancreas to signal cells to break down glycogen into glucose for the blood.

Both instances are examples of negative feedback in that the hormone being released reverts the blood glucose level back to within the homeostatic range. Am I thinking about this correctly?

I was confusing the second case...
