When two or more hormones work together to produce a particular result, their effects are said to be synergistic. These effects may be additive or complementary. The action of epinephrine and norepinephrine on the heart is a good example of an additive effect. Each of these hormones separately produces an increase in cardiac rate; acting together in the same concentrations, they stimulate an even greater increase in cardiac rate.
The synergistic action of FSH and testosterone is an example of a complementary effect; each hormone separately stimulates a different stage of spermatogenesis during puberty, so that both hormones together are needed at that time to complete sperm development.
Likewise, the ability of mammary glands to produce and secrete milk requires the synergistic action of many hormones-estrogen, cortisol, prolactin, oxytocin, and others.

Steroids
estrogen, progesterone, and testosterone
Endocrine glands release hormones. These chemical messengers control body processes.

Estrogen and Testosterone
Some examples of hormones that are derived from amino acids include epinephrine, norepinephrine, dopamine, and thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones are synthesized from tyrosine or tryptophan amino acids.

Some examples of tropic hormones include follicle-stimulating hormone (FSH), luteinizing hormone (LH), adrenocorticotropic hormone (ACTH), and thyroid-stimulating hormone (TSH). These hormones regulate the function of other endocrine glands in the body by stimulating them to produce and release their own hormones.
