Pituitary
• Near the base of the skull is the pituitary gland, which releases hormones influencing body chemistry.

Pituitary Gland
• Hyperpituitarism (acromegaly)
• Hypopituitarism (dwarfism)
• Hormones Produced: TSH, GH, ACTH, LH, FSH, PRL, ADH

Thyroid Gland
• On either side of the larynx is the thyroid, producing thyroxine, which controls the rate at which the body converts food into useful energy.

Thyroid Gland
• Hyperthyroidism (Grave’s Disease)
• Hypothyroidism (Cretinism)
• Goiters
TSH, T3, T4, RIA, Iodine Uptake Scan

Grave’s Disease
• Overactivity of thyroid gland
• Affects primarily women 20-40
• Diagnosed by simple blood tests
• Treatment with radioactive iodine
• Treatment can cause hypothyroidism

Thymus Gland
• The thymus is located above the heart and produces lymphocytes, which form a vital part of the body's immune response.

Thymus Gland
• A person with an underactive thymus gland will be prone to getting sick often. Infection will be common and will often be chronic andprolonged

Islets of Langerhans (pancreas)
• The pancreas secretes substances for the digestion of food, such as insulin.
• Can cause problems with excess blood sugar, the major cause of diabetes.

Adrenal Glands
• At the top of the kidneys are the adrenal's that produce several hormones including adrenalin, which stimulates the "fight or flight" response

Cushing’s Disease
• Cushing’s Disease (hypersecretion of cortisol)
• Cohn’s Syndrome (hypersecretion of aldosterone)

Diabetes Insipidus
• Insufficient secretion of vasopressin and ADH which regulate kidneys to release urine
• Polyuria of 4-16 liters/day 9normal output: 2 or less liters/day
