Alicia Resmer, Period 5: Endocrine System

Major Functions of Endocrine System

Major endocrine glands/organs and their functions (separate by region/ body cavity)
• Include the hormones produced, their functions and their target organs

Compare and contrast steroid vs. non-steroid hormones and list the hormones for each
category

Homeostatic mechanisms of hormone regulation (negative and positive feedback)

Diseases associated with the endocrine system

Endocrine glands release hormones into bloodstreams

Metabolism, Homeostasis, Growth/Development, Sexual Function, Reproduction, Sleep-Wake Cycle, Mood

Pineal Gland

Hypothalamus

Thyroid

Pituitary Gland (Grand Master)

Thymus

Pancreas

Adrenal Glands

Kidneys

Ovaries

Testes

Parathyroid

Melatonin- helps body relax, sleep-cycle, metabolism

Growth- Regulates Growth

Estrogen- Regulates development of uterus, growth/development, Reproduction and Progesterone

Progesterone- Contraception, Luteal phase support, prepare uterus

Testosterone- Regulate Sex Drive, Bone mass, Fat distribution, Muscle Mass, RBC, Sperm

Erythropoietin- Stimulate production and maintenance of RBC's

Aldosterone- Helps control salt and water balance in kidney (keep sodium in and release potassium)

Cortisol- Control glucose levels in blood, respond to danger and stress

Insulin- Lowers blood sugar, regulates energy supply by balancing micronutrients

Glucagon- Increase blood sugar, Keeps blood sugar from getting too low

Corticotrophin- Regulates HPA axis

Thymosin- Stimulates T-Cell production for immune system, control inflammation and immunity

Thymopoietin: fuels T-Cell production and send signal to pineal gland to produce hormones

Parathyroid Hormone- control calcium levels in blood

Thyroxine- Controls Metabolic Rate

Calcitonin- Blocks osteoclasts activity (Controls calcium amount)

Thyroid Stimulating- Tells Thyroid to produce hormones

Prolactin- Controls breast milk production

Adrenocorticotrophic- tells adrenals to make hormones

Follicle Stim and Lutenising- Reproductive

Gonadotropin- Stimulates pituitary to stimuate FSH and LH

TRH- stimulate Thyroid

Steroid- Directly Active, Related to Cholesterol, Lipid Soluble

Non-Steroid: Inactive, Protein, Amino Acid, Nonlipid soluble, Pituitary and Hypothalamic

Testosterone, Progesterone, Estrogen, Aldosterone, Cortisol

Antidiuretic, Oxytocin, Thyrotropin, Gonadotropin, GH, ACTH, LH, Thyroid Stimulating, FSH

Blood Level, Sugar Level, Blood Pressure

Diabetes- Not enough insulin, high blood sugar :

PCOS- Cysts that form on ovaries

Hypothyroidism- High risk heart failure, underactive thyroid

Acromegaly- abnormal growth caused by overproduction of growth hormone

Prolactinoma- too much prolactin
