Question

How is hormone production and release primarily controlled?

Short answer

The hormone levels in blood are kept within a specific range in this way.

Step-by-step solution

Hormones Production

For instance, the thyroid receives a signal from the anterior pituitary to release thyroid hormones. In turn, the hypothalamus and anterior pituitary receive feedback from rising levels of these hormones in the blood, which prevents the thyroid gland from receiving additional signals.

Stimulus

A stimulus causes the release of a substance in negative feedback systems; when the substance reaches a specific level, it sends a signal that prevents further release of the substance.
