What is shorter?
In response to a rise in blood sugar the pancreas releases insulin. Likewise, low blood sugar levels result in glucagon release. What type of hormone secretion regulation is this?
What is humoral?

What is the sympathetic NS?
More of these have to appear on the surface of cells to become more sensitive to a particular hormone.
What are hormone receptors?
