The pituitary gland is located in the brain and hangs below the hypothalamus. This gland is also called the master gland because it is responsible for controlling the growth and regulating the activity of other glands in the body. The pituitary gland is still controlled by information sent to the hypothalamus. It is known that the adrenal glands are responsible for changing energy level, mood, and how a person is able to deal with stress. The adrenal glands release adrenaline and norepinephrine. Adrenaline works by stimulating organs made up of smooth muscles, such as the stomach, heart and intestines. Norepinephrine interacts with the liver and pituitary gland to control a wide variety of internal sensations in the body. Since the hormones secreted by the adrenal glands are vital in an emergency situation, they also function and operate as neurotransmitters. Once adrenaline and norepinephrine turn into neurotransmitters, they become epinephrine and norepinephrine. Both have much faster effects on the body than any other type of hormone released by other glands in the endocrine system (Weebly,
