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. Hormones and the Endocrine System Share on Facebook Share on Twitter Share on Linkedin Share on Pinterest Share via Email Print this Page Endocrine System Adrenal Gland Procedures The endocrine system uses hormones to control and coordinate your body's internal metabolism or homeostasis energy level, reproduction, growth and development, and response to injury, stress, and environmental factors.
Consider the following hormones and their role in the workings of the endocrine system: Where the hormone is produced Hormone s secreted Hormone function Adrenal glands Aldosterone Regulates salt, water balance, and blood pressure Adrenal glands Corticosteroid Controls key functions in the body; acts as an anti-inflammatory; maintains blood sugar levels, blood pressure, and muscle strength; regulates salt and water balance Pituitary gland Antidiuretic hormone vasopressin Affects water retention in kidneys; controls blood pressure Pituitary gland Adrenocorticotropic hormone ACTH Controls production of sex hormones estrogen in women and testosterone in men and the production of eggs in women and sperm in men.
Affects growth and development; stimulates protein production; affects fat distribution. That is why too much or too little of a certain hormone can be serious. Laboratory tests can measure the hormone levels in your blood, urine, or saliva.
Your health care provider may perform these tests if you have symptoms of a hormone disorder. Home pregnancy tests are similar - they test for pregnancy hormones in your urine. The information on this site should not be used as a substitute for professional medical care or advice.

Interruptions to natural darkness impair melatonin levels and sleep quality. For instance, late-night exposure to the blue light of screens can interrupt natural sleep patterns. If you are depleted in estrogen, you may have low moods or depression.
When estrogen levels fluctuate, as they do during menopause, you may experience hot flashes, low libido, and weight gain. Low levels of testosterone cause erectile dysfunction, low sex drive, decreased semen production, loss of muscle, and low bone density.
Cortisol is the stress hormone. At The Well for Health, we know that balanced hormones are essential for your overall health and wellness.
