Endocrine system (Lecture) Flashcards
Thyroid function
Metabolic hormone synthesis
Cretinism
Hypo secretion of thread in infants
- Mental retardation & other physical abnormalities
Myxedema
Hyposecretion in Adults
- Iodine deficiency
- Low Metabolic rate (no retardation)
Pituitary Dwarfism
Hypo secretion of G.H.
Diabetes Mellitus
Insulin hyposecretion / failing Pancreas
Adrenal Cortex location
Above Kidney
Cushing’s Disease
- Adrenal cortex hyper secretion
- Persistent hyperglycemia
Addisons Disease
- Hyposecretion of adrenal cortex
- weight loss/ sodium levels drop / potassium levels rise / severe dehydration
Graves Disease
Thyroid Autoimmune disease
- antibodies minic Thyroid hormone (hypersecretion)
Parathyroid Gland

- Produces calcium and harvests from bone when necessary
Adrenal Medulla
Hormone controlling fight or flight reaction
Hypophysis
hormones which stimulate other endocrine glands
- small, the size of a pea
Steroids
(metabolized in the liver)
- Estrogen
- Testosterone
- Cortisone
- Androgen
- Aldosterone
