|
Function
|
Adrenocorticotrophic
hormone (ACTH)
|
Adrenal
glands
|
Stimulates the adrenal glands to produce cortisol. Cortisol is important
in controlling your metabolism, blood sugar levels and blood pressure. It is
also an anti-inflammatory agent, and helps your body to resist certain
stresses such as bleeding or fasting.
|
Follicle-stimulating
hormone (FSH)
|
Ovaries
(women)
Testes (men) |
Stimulates the ovaries to produce an ovum (egg) for fertilisation. Also
causes an increase in the hormone oestrogen.
Stimulates the testes to produce sperm. |
Growth
hormone (GH)
|
Many different cells of the body
|
The most well-known effect in children is to increase height. In adults
and children it helps to control the amount of muscle and fat in the body. It
also helps to heal injuries and it promotes your immune system.
|
Luteinising
hormone (LH)
|
Ovaries
(women)
Testes (men) |
Triggers ovulation - the release of what will become an ovum (egg) ready
for fertilisation.
Stimulates cells in the testes to produce testosterone |
Melanocyte-stimulating
hormone (MSH)
|
Brain?
|
The exact role in humans is unknown. It may influence brain activity;
when too much is present, it may cause darkening of the skin.
|
Prolactin
|
Breasts
|
Together with other hormones, prolactin stimulates the breasts to produce
milk.
It is also found in women who aren’t pregnant. Men also have prolactin, but its function is not understood well. |
Thyroid-stimulating
hormone (TSH)
|
Thyroid
gland
|
TSH stimulates the thyroid gland to produce its own hormones,
triiodothyronine (T3) and thyroxine (T4).
These hormones help to control many bodily functions, including heart rate, temperature and metabolism. |
The posterior pituitary
makes and releases just two hormones

Antidiuretic
hormone (ADH)
|
Kidneys
|
Decreases urine production. (It causes more water filtered by the kidneys
to be returned to the blood. This decreases the amount of urine.)
ADH also causes a rise in blood pressure. |
||
Oxytocin
|
Breasts
and uterus
|
Stimulates contraction of the uterus (womb) during childbirth. Helps
breasts to release milk.

Acromegalia
https://en.wikipedia.org/wiki/Acromegaly
Facial aspect of a patient with acromegaly. The nose is widened and thickened, the cheekbones are obvious, the forehead bulges, the lips are thick and the facial lines are marked. The forehead and overlying skin is thickened, sometimes leading to frontal bossing.

Compared with the hand of a typical person (left), the
hand of a patient with acromegaly (right) is enlarged, with fingers that are
widened, thickened and stubby, and with thicker soft tissue
