Where is the thyroid gland located?
2
Endocrine System Homeostatic Imbalances
Ch. 9c
3
Hypo- vs. Hyper- Hypo – Hyper – Less than normal; deficient
Hyposecretion Deficient hormone secretion Hyper – Excessive Hypersecretion Excessive hormone secretion
4
Pituitary Gland Imbalances
Hyposecretion of GH (Growth Hormone) Dwarfism Body proportions still fairly normal but with a maximum height of 4 feet Hypersecretion of GH Gigantism 8-9 feet is common Most cases of hypersecretion results from a tumor of the affected gland
5
Thyroid Gland Imbalances
Goiters (Hyposecretion) An enlargement of the thyroid due to an iodine deficiency Graves’ Disease (Hypersecretion) High metabolic rate Rapid heartbeat Bulging eyes
6
Parathyroid Gland Imbalances
Hyposecretion Low blood calcium levels irritate neurons Irritated neurons deliver rapid impulses to muscles causing uncontrollable spasms Hypersecretion Massive bone destruction Bones become very fragile and spontaneous fractures occur
7
Adrenal Gland Imbalances
Addison’s Disease (Hyposecretion) Peculiar bronze skin tone Sodium and water are lost from the body causing muscle weakness Cushing Syndrome Results from a tumor on the adrenal cortex Symptoms include a wide “moon face” and a hump ion the upper back “Moon Face” “Buffalo Hump”
