What is a hormone produced by adrenal glands?

Answer 1

The adrenal glands consist of the adrenal cortex and the adrenal medulla, which perform separate functions.

The adrenal cortex, the outer portion of the adrenal gland, secretes hormones that have an effect on the body's metabolism, on chemicals in the blood, and on certain body characteristics. The adrenal cortex secretes corticosteroids and other hormones directly into the bloodstream. The hormones produced by the adrenal cortex include:

· corticosteroid hormones

o hydrocortisone hormone - this hormone, also known as cortisol, controls the body's use of fats, proteins, and carbohydrates.

o corticosterone - this hormone, together with hydrocortisone hormones, suppresses inflammatory reactions in the body and also affects the immune system.

· aldosterone hormone - this hormone inhibits the level of sodium excreted into the urine, maintaining blood volume and blood pressure.

· androgenic steroids (androgen hormones) - these hormones have minimal effect on the development of male characteristics.

The adrenal medulla, the inner part of the adrenal gland, is not essential, but helps in coping with physical and emotional stress. The adrenal medulla secretes the following hormones:

· epinephrine (also called adrenaline) - this hormone increases the heart rate and force of heart contractions, facilitates blood flow to the muscles and brain, causes relaxation of smooth muscles, helps with conversion of glycogen to glucose in the liver, and other activities.

· norepinephrine (also called noradrenaline) - this hormone has strong vasoconstrictive effects, thus increasing blood pressure.

Answer 2

Adrenaline is a hormone secreted by the adrenal gland, it is also called Epinephrine. Adrenal Gland is either of the two small dissimilarly shaped endocrine glands, one located above each kidney. Adrenaline helps the body to adjust to sudden stress.

When a person becomes angry or frightened, the adrenal gland release adrenaline into the blood. The hormone causes changes in the body to make it more efficient for "fight or flight".

Adrenaline increases the strength and rate of the heartbeat and raises the blood pressure. It also speeds up the conversion of glycogen into glucose, which provide energy to the muscles.

One of a good example is ; When there is fire, a person can suddenly carry a heavy stuff that he/she cannot usually carry in normal condition. It is the adrenalin hormone that is responsible in that sudden strength.

Adrenaline can be extracted from the adrenal glands of animals or can be chemically synthesized and can be used to treat some sickness.

Answer 3

The adrenal glands secrete the neurotransmitter epinephrine (also called adrenalin), as well as norepinephrine. They also produce a wide range of steroids, some of which are androgens and androgen precursors. The adrenal glands are glands of the endocrine system, responsible for releasing hormones in response to stress.

Answer 4

The hormone adrenaline is a type of stress hormone. It is one of two with the other being cortisol. Adrenaline cause the 'fight or flight' response.

Answer 5

The clue is in your badly phrased question. The ADRENAL gland secretes Adrenaline.

Adrenaline and norepinephrine
