sarz5 — 2014-02-12 19:53:51 UTC

Oestrogen is secreted by the ovaries. It is one of the females primary sex hormones. It prepares the eggs for release and thickens the lining of the womb. It helps with the problems caused by the menopaus

Growth hormone

2014-02-12 19:54:18 UTC

Produced in the Pituitary gland

Also known as somototropin or somotropin

is a peptide hormone that stimulates; growth,

cell reproduction and regeneration.

Insulin -

2014-02-12 19:54:34 UTC

Insulin is an amino acid based hormone secreted by the pancreas to regulate carbohydrate and fat metabolism.

Anti-diuretic hormone (ADH)

2014-02-12 19:54:45 UTC

ADH is made by special nerves in the hypothalmus, and is released into the bloodstream from the pituitary gland. ADH helps control blood pressure and regulate fluid volume in the body by decreasing the amount of water passed in urine

Adrenaline

2014-02-12 19:55:11 UTC

Secreted by the medulla of the adrenal gland. It increases blood pressure especially in times of stress.

Follicle stimulating hormone (FSH)

2014-02-12 19:55:13 UTC

Secreted by the pituitary gland. It regulates the development, growth, puberty and reproductive processes in humans.

Thyroid stimulating hormone (TSH)

2014-02-12 19:55:14 UTC

Releases thyroxin from the thyroid gland. Not enough TSH means the thyroid is under active too much and the thyroid is overactive.

Aldosterone

2014-02-12 19:55:16 UTC

It is a steroid hormone, produced by the adrenal cortex in the adrenal gland.

Plays central role in regulation of the blood pressure

Acts on the distal tubules and collecting ducts of the nephron

to regulate sodium levels

Glucagon

2014-02-12 19:56:23 UTC

Secreted by the pancreas.

Its function is to raise glucose levels in the blood

Growth hormone releasing hormone

2014-02-12 19:58:13 UTC

Is found in the hypothalamus and secreted by the anterior pituitary gland.

The function of GHRH is to regulate the release of the growth hormone

Thyrotropin Releasing Hormone (TRH)

2014-02-12 19:59:03 UTC

Made by nerve cells in hypothalamus

Regulates the secretion of

thyroid stimulating hormone (TSH) in the anterior pituitary gland

Prolactin

2014-02-12 20:01:35 UTC

Produced by the pituitary gland.

Is responsible for the production of milk in females.

Progesterone

sarz5 — 2014-02-12 20:02:20 UTC

Progesterone is secreted by the ovaries and the placenta. It thickens the lining of the womb. It also helps to maintain pregnancy

Corticotropin releasing hormone

2014-02-12 20:02:48 UTC

Made by the hypothalamus and stimulates the release of corticotropin by the anterior pituitary gland

Cortisol

2014-02-12 20:04:28 UTC

Produced by the adrenal cortex as a response to stress.

It increases blood sugar, suppresses the immune system and helps metabolize fat, proteins and carbohydrates.

Parathyroid Hormone/Parathormone

sarz5 — 2014-02-12 20:04:42 UTC

It helps to control the levels of calcium in the body.

Thyroxine

2014-02-12 20:05:31 UTC

Produced by the thyroid gland.

It's main function is to regulate the body's metabolism.

Adrenocorticotrophic Hormone (ACTH)

2014-02-12 20:06:24 UTC

Secreted by the pituitary gland, its main function is to stimulate the growth and and secretion of the cells within the adrenal cortex

Calcitonin

2014-02-12 20:09:02 UTC

Produced by the thyroid gland to decrease blood calcium levels by depositing calcium into the bones.

Oxytocin

2014-02-12 20:10:08 UTC

Secreted by the posterior pituitary gland, It is used clinically to induce labour, control bleeding following delivery and stimulate the production of breast milk.

Luteinising Hormone

2014-02-12 20:11:59 UTC

Produced in the anterior pituitary gland.

Triggers ovulation in females.

It stimulates the production of testosterone in men.

Testosterone
