essary, sound the alarm. (Figure 2.) The receptor, in a state of alert, immedi-
ately sends a message to the pituitary gland located at the rear of the brain.
(Figure 3.)
At this point, various important questions need to be considered.
How do these receptors know the location—and existence—of the pituitary
gland? Moreover, how did they learn that help will be forthcoming from
that gland in an emergency? No doubt that the answer to all these ques-
tions is the inspiration of our Almighty Lord. As with all the living things
He has created, Almighty God, Lord of infinite might, inspires these recep-
tors with the most perfect knowledge to fulfill their responsibilities.
As soon as the pituitary gland receives the message, it begins to re-
lease into the bloodstream greater amounts of the hormone vasopressin
stored inside it. However, what kind of message does
the pituitary gland receive?
How is the pituitary gland
able to understand a mes-
sage from another organ
and immediately go into
action by evaluating it?
These extraordinary mira-
