regulates the gonads (testes and ovaries)
Growth hormone
stimulates growth and targets bones and skeletal muscles
Half life- the length of time it takes for a hormones blood level to decrease by half; it can be anywhere from a fraction of a minute to a week

stimulates milk in females
Target cells-
what a hormone acts on and they alter cell activity by increasing or decreasing the rate of the normal cellular process

Stimulates the thyroid and causes it to secrete hormones
Tropic hormone
regulate the secretory action of other endocrine glands
Hormone-
chemical messengers released into the blood to be transported through the body
Dwarfism-
the growth hormone deficiency in children
Neural stimuli
the release of hormones in response to nerve fiber stimulation (ex: norepinephrine and epinephrine)
