Hormones - CORRECT ANSWER-chemical messengers secreted into the
bloodstream primarily by endocrine glands
neurotransmitters - CORRECT ANSWER-released by nerves
pineal gland, hypothalamus, pituitary gland - CORRECT ANSWER-the main
center for endocrine function on the brain
target organ cells - CORRECT ANSWER-Cells acted on by hormones
nonsteroid hormones - CORRECT ANSWER-first messengers, bind to receptors
on the target cell's membrane
steroid hormones - CORRECT ANSWER-hormones that bind to receptors within
the target cell nucleus
negative feedback - CORRECT ANSWER-A primary mechanism of homeostasis,
whereby a change in a physiological variable that is being monitored triggers a
response that counteracts the initial fluctuation.
positive feedback - CORRECT ANSWER-Feedback that tends to magnify a
process or increase its output, uncommon, only occurs in pregnancy and fevers
hypersecretion - CORRECT ANSWER-abnormally increased secretion
hyposecretion - CORRECT ANSWER-abnormally decreased secretion
target cell insensitivity - CORRECT ANSWER-produces results similar to
hyposecretion
ADH and oxytocin - CORRECT ANSWER-posterior pituitary hormones
