The Pineal GlandInvolved in: Sleep cycles, circadian rhythms
Hormone produced:Melatonin

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 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
![Page 12: The Endocrine System Biology 12 Ms. Bowie](https://reader036.vdocuments.net/reader036/viewer/2022062306/5a4d1afc7f8b9ab05998480b/html5/thumbnails/12.jpg)
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
