Final exam study guide 2023: nurs
308 NIU!! #41 questions and
answers.100% correct.
1. Stimulation of the insulin- secreting cells of the pancreas by
the autonomic nervous system are an example of what type of
control? - -neural control
-2. Know the feedback mechanism for thyroid hormones; i.e,
thyroid- stimulating hormone (TSH) and thyroxine - -Positive
feedback occurs when a neural, chemical, or endocrine response
increases the synthesis and secretion of a hormone.
Negative feedback occurs when the stimulus decreases the
synthesis and secretion of the hormone.
-3. Which hormones are water-soluble? - -Growth hormone (GH)
Insulin
Epinephrine
Norepinephrine
Prolactin
Calcitonin
-4. Identify the type of target cells responses when adapting to
high or low hormone concentrations, and either up or down-
regulation. - -Up-regulation: low concentration of hormone that
increases affinity of receptors per cell
Down-regulation: high concentration of hormone that decreases
affinity of receptors per cell
-5. Which organ inhibits prolactin-inhibiting factor from acting
on target tissue? - -Hypothalamus
-Which hormones are released from the posterior pituitary? - -
ADH & Oxytocin
