Definition:
Hormones are signaling molecules made by your glands.
Hormones communicate btwn parts of the body.
Hormones help to regulate physiological & behavioural activities
such as sleeping, digestion, breathing etc…
Hormone agonists stimulate hormone receptors.
The pituitary gland is sometimes
called the "master" gland of the
endocrine system because it controls
the functions of many of the other
endocrine glands.
