A

superior and inferior thyroid arteries

17
Q

thyroid sits on what important nerves

A

recurrent laryngeal nerves

18
Q

the recurrent laryngeal nerves are branches of

A

the vagus nerve

19
Q

the recurrent laryngeal nerves control

A

our ability to speak

20
Q

the recurrent laryngeal nerves attach to

A

skeletal muscles of the larynx

21
Q

What controls the thyroid gland

A

The hypothalamic pituitary gland system

22
Q

What is the decision maker to stimulate the thyroid?

A

The hypothalamus

23
Q

The hypothalamus is connected to the

A

anterior pituitary gland

24
Q

TRH stands for

A

thyrotropin releasing hormone

25
TRH receptors are located
in the anterior pituitary gland
26
The anterior pituitary gland releases
TSH
27
The T on T3 or T4 indicates
how many iodines the compound has
28
which compound shuts down the pit gland's tsh release
thyroxine (t4)
29
how is the thyroid system regulated
temperature and stress
30
reduced temperature will cause
increase in thyroid hormone
31
the posterior pituitary releases
ADH
32
symptoms of thyroid storm
elevated hr, temp, o2 consumption, ventilation
