Disorders of the Endocrine System
Hyperfunction: too much hormone being produced
Hypofunction: not enough hormone being produced
Disease Occurs due to Irregular Amounts of Hormones Being Produced
Hyperfunction of the pituitary so too much growth hormone is produced during childhood
Symptoms: ◦ Excessive height
Gigantism
Hyperfunction of the pituitary so too much growth hormone is produced in adulthood
Symptoms: Overdevelopment of bones in the face, hands, and feet; protruding chin
Acromegaly
Hypofunction of the pituitary so not enough growth hormone is produced in childhood
Symptoms: Short stature
Dwarfism
Thyroid produces too much thyroxine
Symptoms:◦ Goiter: Enlargement of
the thyroid gland◦ Exophthalmos: Bulging
eyeballs
Hyperthyroidism
Thyroid does not produce enough thyroxine Symptoms:
◦ Obesity◦ Dry, itchy skin◦ Dry, brittle hair◦ Muscle cramps
Hypothyroidism
Hyperfunction of the parathyroid causing it to produce too much parathyroid hormone
Decreased calcium levels effect the function of the nerves
Symptoms:◦ Convulsive twitching develops◦ Person dies due to spasms of the respiratory
muscles
Tetany
Hyperfunction of the adrenal cortex which causes and increase in adrenocorticosteroids
Symptoms:◦ Obesity◦ Muscle weakness◦ High blood pressure◦ Excessive hair growth◦ Buffalo hump
Cushings’ Syndrome
Hypofunction of the adrenal cortex results in not enough adrendocorticosteriods produced
Symptoms:◦ Bronzing of the skin◦ Not enough glucose in the blood◦ Low blood pressure
