The pituitary gland stimulates the thyroid.

Explanation:

The pituitary gland produces thyroid stimulating hormone (TSH).

TSH stimulates the thyroid gland to produce the hormones triiodothyronine (T3) and thyroxine (T4).

The thyroid hormones in turn inhibit the pituitary to slow down/stop the production of TSH. This is negative feedback system, a neat way of the body to regulate the hormone levels.
