thyroid is regulator of - CORRECT ANSWER - growth and metabolism
what hormones does thyroid secrete - CORRECT ANSWER - thyroxine (T4) the main
hormone
triiodothyronine (T3)
calcitonin (calcium regulation)
can we feel thyroid in EO exam - CORRECT ANSWER - only if it is abnormal, usually
not
TSH - CORRECT ANSWER - thyroid stimulating hormones relased by pituitary
TRH - CORRECT ANSWER - thyrotropin released by hypothallus
feedback of hormones - CORRECT ANSWER - Hypothalamus release TRH > pituitary
releases TSH > thyroid releases T3 and T4
in normal conditions T4 T3 synthesis are controlled by what feedback - CORRECT
ANSWER - negative feedback
hypothalamus Thyrotropin releasing hormone (TRH) stimulates the pituitary to release
(________________), which causes the thyroid to secrete ________ - CORRECT
ANSWER - thyroid stimulating hormone, T3 and T4
,if you don't have enough iodine this can cause low levels of - CORRECT ANSWER - T3
and T4, which will then increase TSH in feedback loop. we need iodine T3 and T4 to synthesis
the iodine
high TSH can indicate - CORRECT ANSWER - hypothyroidism
T4 can be used to make - CORRECT ANSWER - T3
conversion of T3 and T4 can be inhibited by - CORRECT ANSWER - fasting steriods and
some drugs
minimum daily requirement is ___ mg of iodine - CORRECT ANSWER - 75mg
thyroid - CORRECT ANSWER - growth and cellular respiration
sites of action of thyroid hormones - CORRECT ANSWER - cell nucleus, mitochondria,
cell membrane, adrenergic receptors
why are thyroid hormones important - CORRECT ANSWER - energy synthesis, proper
oxygen consumption on cellular level, healing
calcitonin regulates - CORRECT ANSWER - calcium and phosphorous levels and skeletal
remodeling

thyrotoxicisis
hyperthyroidism more common in - CORRECT ANSWER - women- puberty or
menaposal women
what can cause hyperthyroidism - CORRECT ANSWER - exctopic (extra) thyroid tissue
pituitary disease

own immune system attacks itself.
aquired immunodeficiency = HIV and can progress to aids. virus affects blood cell and immune
system gets destroyed. they become immunocompromised.
how to treat graves disease - CORRECT ANSWER - radioactive iodine, remove thyroid
which will cause hypothyroidism, but they'll die if we don't treat hyperthyroidism
