What are the two major groups of hormones and what are their derivatives? - ANSWER-1- Peptide
(derived from proteins and catecholamines)
2- Steroids (derived from cholesterol)
Hormones can react with cells that have what on their cell surface? - ANSWER-Receptor

7. Hypothalamus
Name three secondary endocrine organs. - ANSWER-Heart, thymus, kidneys, gonads
Describe homeostasis in the body. - ANSWER-a set point aka thermostat. A range in which body acts
to maintain all its levels for function
During negative feedback a hormone level is high. What happens to hormone production? - ANSWER-
The brain detects the hormone level is too high and hormone production is shut off.
The action of oxytocin works through positive or negative feedback? - ANSWER-Positive feedback.
Why are the neurons in the hypothalamus called neurosecretory cells? - ANSWER-They are cells that
respond to neurotransmitters and produce hormones.

pituitary
The posterior pituitary gland stores what two main hormones? - ANSWER-ADH and Oxytocin
