The Endocrine System Biology 12 Ms. Bowie

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

The Pituitary Gland THE MASTER GLAND Divided in to 2 parts: The Anterior pituitary The Posterior Pituitary

The Pituitary Gland THE 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 Gland THE MASTER GLAND The Posterior Pituitary Involved: Storage & release of 3 two hormones produced in the hypothalamus Hormones: thyroid-stimulating hormone (TSH), follicle-stimulating hormone (FSH), luteinizing hormone (LH),

The Thyroid Gland Involved in: Hormone produced: Metabolism Blood pressure Regulation of tissue growth Decrease calcium levels in blood Hormone produced: Thyroxine Calcitonin

The Parathyroid Gland Involved in: Hormone produced: Increases calcium levels in blood Hormone produced: Parathyroid hormone

The Thymus Gland Involved in: Hormone produced: Maturation & Training of Immune Cells (T-Cells, etc.) Hormone produced: Thymosin

The Adrenal Glands Separated into 2 parts: The Adrenal Cortex The Adrenal Medulla

The Adrenal Cortex Involved in: Hormone produced: Long term stress response Increase blood glucose Increase blood volume & pressure Immune suppression Water retention Hormone produced: Glucocorticoids Mineralcorticoids

The Adrenal Medulla Involved in: Hormone produced: 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 Pancreas Islets of Langerhans Involved in: Blood glucose regulation Hormone produced: Insulin (Beta cells) Decrease blood sugar levels Glucagon (Alpha cells) Increase blood sugar levels

The Ovaries Involved in: Hormone produced: Female reproduction Female body shape Hormone produced: Estrogens Progesterone

The Testes Involved in: Hormone produced: Male reproduction (production of sperm) Male sex characteristics (e.g. Deep voice, muscle mass, body hair, etc. Hormone produced: Testosterone (androgen)
