Endocrine System
Hormones
-
-
-
-
-
Growth Hormone
stimulating body growth is to stimulate the liver and other tissues to secrete IGF-I. IGF-I stimulates proliferation resulting in bone growth
-
-
-
Thyroid Hormone
increase the basal metabolic rate, affect protein synthesis, help regulate long bone growth and neural maturation
Thyroxine(T4)
plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones
Triiodothyronine(T3)
plays vital roles in the body's metabolic rate, heart and digestive functions, muscle control, brain development and function, and the maintenance of bones.

-
Parathyroid Horomone
regulates calcium levels in the blood, largely by increasing the levels when they are too low
Sex Hormones
Estrogens
development of female secondary sexual characteristics. These includes breasts, endometrium, regulation of the menstrual cycle etc. In males estrogen helps in maturation of the sperm and maintenance of a healthy libido.
Androgens
regulate the function of many organs, including the reproductive tract, bone, kidneys, liver and muscle
-
Aldosterone
causes water to be reabsorbed along with sodium; this increases blood volume and therefore blood pressure
-
-
Insulin
Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy

Major Glands and Organs
Parathyroid Glands
The parathyroids produce a hormone called parathyroid hormone (PTH). PTH raises the blood calcium level by: breaking down the bone (where most of the body's calcium is stored) and causing calcium release. increasing the body's ability to absorb calcium from food
Thymus Gland
important function both in the immune system and endocrine system. Though the thymus begins to atrophy (decay) during puberty, its effect in "training" T lymphocytes to fight infections and even cancer lasts for a lifetime
Thyroid Gland
The thyroid gland produces hormones that regulate the body's metabolic rate as well as heart and digestive function, muscle control, brain development, mood and bone maintenance.
Adrenal Glands
Adrenal glands produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions.
-
Pancreas
releases juices directly into the bloodstream, and it has an exocrine function because it releases juices into ducts
Hypothalamus
The hypothalamus controls body temperature, hunger, important aspects of parenting and attachment behaviours, thirst, fatigue, sleep, and circadian rhythms.
Ovaries/Testes
These organs are responsible for producing the sperm and ova, but they also secrete hormones
Pineal Gland
Its function isn't fully understood. Researchers do know that it produces and regulates some hormones, including melatonin.
Diseases
Goiters
Not all goiters cause symptoms. Symptoms that do occur might include swelling, and cough. Rarely, symptoms may include throat tightness or trouble breathing
Graves
Symptoms include anxiety, hand tremor, heat sensitivity, weight loss, puffy eyes and enlarged thyroid
Hypothyroidism
Major symptoms include fatigue, cold sensitivity, constipation, dry skin, and unexplained weight gain
Hyperthyroidism
Symptoms include unexpected weight loss, rapid or irregular heartbeat, sweating, and irritability, although the elderly often experience no symptoms
Hyperparathyroidism
Often symptoms take a long time to develop. When they do occur, they include fragile bones, kidney stones, and excessive urination
Addison's Disease
Symptoms tend to be non-specific and include fatigue, nausea, darkening of the skin, and dizziness upon standing
Cushing's Syndrome
Signs are a fatty hump between the shoulders, a rounded face, and pink or purple stretch marks
Diabetes
Often, there are no symptoms. When symptoms do occur, they include excessive thirst or urination, fatigue, weight loss, or blurred vision
Major Functions
The endocrine system maintains homeostasis by releasing hormones, and control prolonged or continuous processes like growing, development, reproduction, and metabolism.
