Ella's blood test reveals high level of thyroid
stimulating hormone ( TSH) but low levels of triodothyronine (T3)
and thyroxine (T4). Are these results are normal or do they reveal
a homeostatic imbalance? Explain to support your answer?
Write a paragraph on the mechanism of thyroid stimulating hormone.
Using the following pathway:
Hypothalamus—> TRH—> blood —> Anterior pituitary—>
TSH—> blood —> thyroid gland
T3 is a thyroid hormone we learned about earlier this semester.
Researchers and workers that overwinter in Antarctica are often
subject to a disorder called Polar T3 Syndrome where they
experience cognitive impairment and mood disturbances. (10)
Why would researchers in Antarctica be subject to this syndrome
and how does it relate to metabolism?
What might be a potential way of treating the syndrome?
Which of following is not secreted by anterior pituitary?
Thyroid stimulating hormone
FSH
Oxytocin
ACTH
Antidiuretic hormone (ADH) is secreted by:
Anterior pituitary
Posterior pituitary
Hypothalamus
Kidneys
Posterior pituitary produces following hormones:
Oxytocin & prolactin
FSH & TSH
Oxytocin & antidiuretic hormone (ADH)
Insulin & ADH
Which of following hormones lowers blood glucose levels?
Insulin
Thyroid hormones
Calcitonin
FSH
What controls anterior pituitary gland?
Hypothalamus
Thalamus
Chemical signals from cerebrospinal fluid
Peripheral nervous system
Using Growth Hormone (GH) as an example, explain a hypothalamic
– pituitary – target organ relationship. A drawing may be helpful
but be sure to include words to explain the picture.
Describe the relationship between parathyroid hormone (PTH) and
blood calcium. Include the three (3) systems PTH targets to alter
blood calcium and explain the effects of inappropriate PTH
secretion (too much PTH and too little PTH).
