In brief: TSH
Tsh- thyroid stimulating hormone is released by the pituitary in response to low thyroid (t4) hormone levels.
Tsh then causes more T4 to be released from the thyroid. High levels of T4 turn off the release of TSH in what is called a negative feedback loop. This process keeps thyroid levels relatively constant.

In brief: TSH vs T4
Tsh stands for thyroid stimulating hormone.
Tsh is secreted by the brain to cause the thyroid to secrete thyroid hormone (t4).
