The endocrine device is made up of glands that produce and also secrete hormones, chemistry substances created in the body that regulate the task of cell or organs. This hormones manage the body's growth, line (the physical and chemical processes of the body), and sexual advancement and function. The hormones are released into the bloodstream and may affect one or several organs throughout the body.

You are watching: Which is not characteristic of the endocrine system?

Hormones room chemical messengers developed by the body. Castle transfer details from one collection of cells to one more to name: coordinates the functions of different parts of the body.

The significant glands of the endocrine mechanism are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and also the reproductive guts (ovaries and also testes). The kidneys is additionally a part of this system; it has actually a duty in hormone production as well as in digestion.

The endocrine mechanism is regulated by feedback in much the same means that a thermostat regulates the temperature in a room. For the hormones that room regulated by the pituitary gland, a signal is sent from the hypothalamus to the pituitary gland in the type of a "releasing hormone," i m sorry stimulates the pituitary come secrete a "stimulating hormone" right into the circulation. The stimulating hormone then signals the target gland come secrete that is hormone. As the level the this hormone rises in the circulation, the hypothalamus and the pituitary gland shut under secretion that the releasing hormone and the stimulating hormone, which in turn slows the cheap by the target gland. This device results in secure blood concentrations of the hormones that room regulated through the pituitary gland.

The hypothalamus is a component of the mind that secretes hormone that control body temperature and metabolism.

The hypothalamus is situated in the lower main part of the brain. This component of the brain is vital in regulation that satiety, metabolism, and body temperature. In aHypothalamus releasing hormone signal secretion of stimulating hormones. The hypothalamus likewise secretes a hormone referred to as somatostatin, which causes the pituitary gland to stop the release of development hormone.

The pituitary gland is situated at the basic of the mind beneath the hypothalamus and also is no larger than a pea. The is often thought about the many important part of the endocrine system because it produces hormone that control many attributes of various other endocrine glands. Once the pituitary gland go not produce one or an ext of its hormone or not enough of them, the is referred to as hypopituitarism.

The pituitary gland is divided into two parts: the anterior lobe and also the posterior lobe. The anterior lobe to produce the adhering to hormones, which room regulated by the hypothalamus:

Adrenocorticotropin hormone (ACTH): Stimulates the adrenal gland to produce several connected steroid hormonesProlactin: Hormone the stimulates milk production in females

The posterior lobe to produce the adhering to hormones, which space not regulated by the hypothalamus:

The hormone secreted through the posterior pituitary are actually produced in the mind and brought to the pituitary gland v nerves. They room stored in the pituitary gland.

The thyroid gland is situated in the reduced front component of the neck. It produces thyroid hormone that regulate the body's metabolism. It also plays a duty in bone expansion and advancement of the brain and nervous system in children. The pituitary gland controls the release of thyroid hormones. Thyroid hormone also aid maintain normal blood pressure, heart rate, digestion, muscle tone, and reproductive functions.


The parathyroid glands space two pairs of tiny glands embedded in the surface ar of the thyroid gland, one pair on each side. They relax parathyroid hormone, which plays a function in regulating calcium levels in the blood and also bone metabolism.

The 2 adrenal glands are triangular-shaped glands situated on peak of each kidney. The adrenal glands are made up of two parts. The outer component is referred to as the adrenal cortex, and the inner part is called the adrenal medulla. The outer component produces hormones dubbed corticosteroids, which control the body's metabolism, the balance the salt and also water in the body, the immune system, and sexual function. The inner part, or adrenal medulla, produce hormones dubbed catecholamines (for example, adrenaline). These hormones assist the body cope v physical and emotional stress and anxiety by boosting the love rate and also blood pressure.
