Endocrine Systems
Hypothalamus-Secretes
Several neurohormones,
such as Dopamine, that
stimulate or inhibit
anterior pituitary function
Pineal gland-Makes
melatonin, which
regulates daily
rhythms and seasonal
reproduction in some
mammals
Parathyroid glands-Make
parathyroid hormone,
which increases blood
calcium
Thyroid-Makes thyroxine
and triiodothyronine,
which regulate metabolic
rate, growth, and
differentiation
Adrenal glands:
Medulla-Makes
epinephrine and
norepinephrine, which
mediate the “fight-orflight” response
Cortex-Makes
aldosterone, which
regulates Na and K
balance in the blood and
makes glucocotricoids
Kidneys-Secrete
erythropoietin, which
regulates production of
red blood cells; also
convert vitamin D to an
active hormone
Pituitary gland:
Anterior Pituitary glandProduces 6 hormones with
diverse actions (ACTH, GH,
TSH, PRL, LH, FSH)
Posterior Pituitary glandSecretes oxytocin and
antidiuretic hormone
Pancreas-Makes insulin,
which lowers blood
glucose, and glucagon,
which raises blood
glucose
Testes-Produce androgens,
such as testosterone,
which control reproduction
in males

Ovaries-Produce
estorgens such as
estradiol, and
progesterone, which
control reproduction in
females
Disorders:
Hyperthyroidism:
Results from excessive
production of the thyroid
hormones T-4 and T-3
Diabetes Mellitus:
The body’s immune
system destroys
pancreatic beta cells,
which make the
hormone insulin
Diabetes Insipidus:
Caused by lack of
the antidiuretic
hormone
vassopressin, which
controls water
balance by
concentrating urine.
Adrenoleukodystrophy:
The enzyme that
breaks down the very
long chain fatty acids
is not produced and
these fatty acids
accumulate in the brain
and adrenal cortex
