Adrenal
Blood sugar

glands into the blood and affect cells
in another part of the body
Hormones
Hormones only work on certain cells, called?
Target Cells
What is the
difference between
nerve and hormone
control?

action is quick (think reflexes) and can
be stopped quickly. Hormone action is
slower to develop and can last a lot
longer
