I strongly suggest having a read of your notes - they should clarify things for you.

Essentially, TRH is released from the hypothalamus which stimulates the release of TSH from the anterior pituitary, which stimulates the release of T3/4 from the thyroid. There's a negative feedback mechanism involved (so when you have plenty of T3/4, that will have a negative feedback on the production of TRH/TSH). That's a very brief overview - as I said, have a look at your notes.
