Study Notes

Hormone Regulation

Hormone release stops once an appropriate level in the blood is reached.
A change in hormone levels in the blood, either an increase or decrease, triggers the release of more hormones.

Hormones of the Anterior Pituitary

The anterior pituitary gland produces six hormones.
Two of these hormones affect non-endocrine targets.
The remaining four hormones stimulate other endocrine glands.

Thyroid Gland

The thyroid gland is located at the base of the throat.
It consists of two lobes connected by a bridge.
It produces two hormones, including thyroxine.

Pineal Gland

The pineal gland is located on the third ventricle of the brain.
It produces melatonin, which helps establish the body's wake and sleep cycles.
