Hormones are the body toàn thân's chemical messengers. They carry information and instructions from one set of cells to another.

The endocrine (EN-duh-krin) system influences almost every cell, organ, and function of our bodies.
What Does the Endocrine System Do?
- Endocrine glands release into the bloodstream. This lets the hormones travel to cells in other parts of the body toàn thân.
- The endocrine hormones help control mood, growth and development, the way our organs work, , and reproduction.
- The endocrine system regulates how much of each hormone is released. This can depend on levels of hormones already in the blood, or on levels of other substances in the blood, like calcium. Many things affect hormone levels, such as stress, infection, and changes in the balance of fluid and minerals in blood.
Too much or too little of any hormone can harm the body toàn thân. Medicines can treat many of these problems.
What Are the Parts of the Endocrine System?
While many parts of the body toàn thân make hormones, the major glands that make up the endocrine system are the:
- hypothalamus
- pituitary
- thyroid
- parathyroids
- adrenals
- pineal body toàn thân
- the ovaries
- the testes
The pancreas is part of the endocrine system and the digestive system. That's because it secretes hormones into the bloodstream, and makes and secretes enzymes into the digestive tract.
Hypothalamus: The hypothalamus (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 (puh-TOO-uh-ter-ee) gland is 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 hormones it makes control many other endocrine glands.
The pituitary gland makes many hormones, such as:
- growth hormone, which stimulates the growth of bone and other body toàn thân tissues and plays a role in the body toàn thân's handling of nutrients and minerals
- prolactin (pro-LAK-tin), which activates milk production in women who are breastfeeding
- thyrotropin (thy-ruh-TRO-pin), which stimulates the thyroid gland to make thyroid hormones
- corticotropin (kor-tih-ko-TRO-pin), which stimulates the adrenal gland to make certain hormones
- antidiuretic (an-ty-dy-uh-REH-tik) hormone, which helps control body toàn thân water balance through its effect on the kidneys
- oxytocin (ahk-see-TOE-sin), which triggers the contractions of the uterus that happen during labor
The pituitary also secretes endorphins (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 and the menstrual cycle in women.
Thyroid: The thyroid (THY-royd) is in the front part of the lower neck. It's shaped like a bow tie or butterfly. It makes the thyroid hormones thyroxine (thy-RAHK-sin) and triiodothyronine (try-eye-oh-doe-THY-ruh-neen). These hormones control the rate 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 toàn thân.
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 (par-uh-THY-roydz). They release parathyroid hormone, which controls the level of calcium in the blood with the help of calcitonin (kal-suh-TOE-nin), which the thyroid makes.
Adrenal Glands: These two triangular adrenal (uh-DREE-nul) glands sit on top of each kidney. The adrenal glands have two parts, each of which makes a set of hormones and has a different function:
Pineal: The pineal (pih-NEE-ul) body toàn thân, also called the pineal gland, is in the middle of the brain. It secretes melatonin (meh-luh-TOE-nin), a hormone that may help regulate when we sleep night and wake in the morning.
Reproductive Glands: The gonads are the main source of sex hormones. In boys the male gonads, or testes (TES-teez), are in the scrotum. They secrete hormones called androgens (AN-druh-junz), the most important of which is (tess-TOSS-tuh-rone). These hormones tell a boy's body toàn thân when it's time to make the changes associated with puberty, like penis and height growth, deepening voice, and growth in facial and pubic hair. Working with hormones from the pituitary gland, testosterone also tells a boy's body toàn thân when it's time to make sperm in the testes.
A girl's gonads, the ovaries (OH-vuh-reez), are in her pelvis. They make eggs and secrete the female hormones (ESS-truh-jen) and (pro-JESS-tuh-rone). Estrogen is involved when a girl starts puberty. During puberty, a girl will have breast growth, start to accumulate body toàn thân fat around the hips and thighs, and have a growth spurt. Estrogen and progesterone are also involved in the regulation of a girl's menstrual cycle. These hormones also play a role in pregnancy.
Pancreas: The pancreas (PAN-kree-us) makes insulin (IN-suh-lin) and glucagon (GLOO-kuh-gawn), which are hormones that control the level of glucose, or sugar, in the blood. Insulin helps keep the body toàn thân supplied with stores of energy. The body toàn thân uses this stored energy for exercise and activity, and it also helps organs work as they should.
Which hormone acts on the same cells that secrete them?
Autocrine action: the hormone acts on the same cell that produced it.What is the name of hormone secreted by?
- The adrenal cortex secretes glucocorticoids, mineralocorticoids, and sex hormones (androgens) . (f) Pancreas: Pancreas secretes insulin and glucagon hormone. (g) Testis: Testosterone is secreted by testis. (h) Ovary: Ovary secretes estrogen, progesterone, and relaxin.What is it called when hormones work together?
The hormones created and released by the glands in your body toàn thân's endocrine system control nearly all the processes in your body toàn thân. These chemicals help coordinate your body toàn thân's functions, from metabolism to growth and development, emotions, mood, sexual function and even sleep. Appointments 216.444.6568.What are hormones Name any two glands and its hormone secretion?
Pituitary gland The anterior pituitary makes and releases the following six hormones: Adrenocorticotropic hormone (ACTH or corticotropin). Follicle-stimulating hormone (FSH). Growth hormone (GH).
