What controls thyroid gland function?
thesized in the anterior pituitary gland
When are TSH levels the highest? during sleep
The body can sense a decrease in T3 levels, and sends
a signal to the brain. The hypothalamus receives the sig-
nal, and makes TRH (thyrotropin releasing hormone). TRH
Explain the process of how T3 is produced then travels to the anterior pituitary, and signals TSH (thy-
roid stimulating hormone) to be made. TSH then travels
to the thyroid and tells the thyroid to produce more T4,
which is converted to T3 in peripheral sites in the body
How is thyroid hormone transported in the body? Thyroxine binding globulin (TBG)
are bound or unbound hormones active? unbound to plasma proteins (the free hormones)
Is T3 or T4 more active? T3 is 4x more active than T4
