The Pineal GlandInvolved in: Sleep cycles, circadian rhythms

Hormone produced:Melatonin

The Pituitary GlandTHE MASTER GLAND

Divided in to 2 parts:The Anterior

pituitaryThe Posterior

Pituitary

The Pituitary GlandTHE MASTER GLAND

The Anterior Pituitary Involved:

Control of most other glands in the body

Produces 7 important hormones: human growth hormone

(hGH), thyroid-stimulating hormone

(TSH), follicle-stimulating hormone

(FSH), luteinizing hormone (LH), prolactin (PRL), adrenocorticotropic

hormone (ACTH), melanocyte-stimulating

hormone (MSH).

The Pituitary GlandTHE MASTER GLAND

The Posterior PituitaryInvolved:

Storage & release of 3 two hormones produced in the hypothalamus

Hormones:thyroid-stimulating

hormone (TSH),follicle-stimulating

hormone (FSH), luteinizing hormone (LH),

The Thyroid GlandInvolved in:

MetabolismBlood pressureRegulation of tissue

growthDecrease calcium

levels in blood

Hormone produced:Thyroxine Calcitonin

The Parathyroid GlandInvolved in:

Increases calcium levels in blood

Hormone produced:Parathyroid

hormone

The Thymus GlandInvolved in:

Maturation & Training of Immune Cells (T-Cells, etc.)

Hormone produced:Thymosin

The Adrenal GlandsSeparated into 2

parts:

The Adrenal

Cortex

The Adrenal

Medulla

The Adrenal CortexInvolved in:

Long term stress response Increase blood

glucose Increase blood volume

& pressure Immune suppression Water retention

Hormone produced:GlucocorticoidsMineralcorticoids

The Adrenal MedullaInvolved in:

Short term stress response (fight or flight) Increase blood glucose Increase heart rate Vasoconstriction Blood diversion from

stomach to muscles

Hormone produced:Epinephrine

(adrenaline)Norepinephrine

The PancreasIslets of Langerhans

Involved in:Blood glucose

regulation

Hormone produced:Insulin (Beta cells)

Decrease blood sugar levels

Glucagon (Alpha cells) Increase blood sugar

levels

The OvariesInvolved in:

Female reproduction

Female body shape

Hormone produced:EstrogensProgesterone

The TestesInvolved in:

Male reproduction (production of sperm)

Male sex characteristics (e.g. Deep voice, muscle mass, body hair, etc.

Hormone produced:Testosterone

(androgen)
