Hypothalamus: The hypothalamus pronounced: hi-po-THAL-uh-mus is in the lower central part of the brain. It links the endocrine system and nervous system. Nerve cells in the hypothalamus make chemicals that control the release of hormones secreted from the pituitary gland.
The hypothalamus gathers information sensed by the brain such as the surrounding temperature, light exposure, and feelings and sends it to the pituitary.
This information influences the hormones that the pituitary makes and releases. Pituitary: The pituitary pronounced: puh-TOO-uh-ter-ee gland is at the base of the brain, and is no bigger than a pea. Despite its small size, the pituitary is often called the "master gland. The pituitary also secretes endorphins pronounced: en-DOR-fins , chemicals that act on the nervous system and reduce feelings of pain.
The pituitary also secretes hormones that signal the reproductive organs to make sex hormones. The pituitary gland also controls ovulation and the menstrual cycle in women.
Thyroid: The thyroid pronounced: THY-royd is in the front part of the lower neck. It's shaped like a bow tie or butterfly. These hormones control the rate at which cells burn fuels from food to make energy.
The more thyroid hormone there is in the bloodstream, the faster chemical reactions happen in the body. Thyroid hormones are important because they help kids' and teens' bones grow and develop, and they also play a role in the development of the brain and nervous system. Parathyroids: Attached to the thyroid are four tiny glands that work together called the parathyroids pronounced: par-uh-THY-roydz.
They release parathyroid hormone, which controls the level of calcium in the blood with the help of calcitonin pronounced: kal-suh-TOE-nin , which the thyroid makes.
The adrenal glands have two parts, each of which makes a set of hormones and has a different function:. Pineal: The pineal pronounced: pih-NEE-ul body, also called the pineal gland, is in the middle of the brain. It secretes melatonin pronounced: meh-luh-TOE-nin , a hormone that may help regulate when you sleep at night and when you wake in the morning. Reproductive Glands: The gonads are the main source of sex hormones. Most people don't realize it, but both guys and girls have gonads.
Like many glands, the adrenal glands work hand-in-hand with the hypothalamus and pituitary gland. The adrenal glands make and release corticosteroid hormones and epinephrine that maintain blood pressure and regulate metabolism. The pancreas is located across the back of the abdomen, behind the stomach. The pancreas plays a role in digestion, as well as hormone production. Hormones produced by the pancreas include insulin and glucagon, which regulate levels of blood sugar.
