Too much growth hormone as a kid
Gigantism
Control center Gland
Hypothalamus
How does the body maintain homeostasis in endocrine system? IE: how are most hormone levels controlled?
Negative feedback loop
You need THIS in your diet to make thyroid hormones.
Iodine
Master GLAND
Pituitary
Type of deficiency: when the gland that produces the actual hormone (not the releasing or stimulating hormones) does not produce it
Primary
These are the most vital hormones produced by the body, and their functions are essential for life: Metabolism, heart rate, growth, fertility, digestion, skin, heat, etc.
Thyroid hormone
3 hormones secreted by thyroid
T3, T4, and Calcitonin
Too much growth hormone as an adult
Acromegaly
The cellular process that occurs within the cells of the body to produce energy and facilitate cellular growth and repair for the purpose of maintaining homeostasis
Metabolism
Type of stimuli: release of hormones in response to changes in extracellular fluid levels or ion levels
Humoral stimuli
Too little growth hormone as a kid
Dwarfism
Clinical manifestations of hypothyroidism
Weight gain, fatigue, weakness, bradycardia, too much cholesterol, muscle aches and cramps, heavier period, depression, memory fog, constipation, goiter, dry skin, hoarseness, cold sensitivity
Type of deficiency: when the gland that produces the releasing or stimulating hormone does not produce it
Secondary
Clinical manifestations of hyperthyroidism
Weight loss, tachycardia, palpitations, irregular heartbeat, sweating, increased appetite, muscle fatigue, light period, nervousness, anxiety, diarrhea, goiter, fine, brittle hair, skin thinning, difficulty sleeping, heat sensitivity
Labs for thyroid disorder
TSH, T3, T4
Clinical Manifestations of Hyperparathyroidism
Bones, Stones, Moans, Groans
Bone demineralization à osteoporosis, fractures; increased risk of kidney stones; polyuria and dehydration; abdominal cramping; dysrhythmias; lethargy, depression. Remember, with too much calcium, the cells are subdued and not excitable.
Endocrine gland associated with CALCIUM
Parathyroid
Acute hypothyroidism resulting in hypotension, hypoglycemia, hypothermia, and loss of consciousness, a life-threatening complication occurring in undiagnosed or untreated elderly patients.
Myxedema coma
Clinical manifestations of HYPOparathyroidism
•Tetany, paresthesia, muscle cramps/twitching, cardiac dysrhythmias. Remember, without calcium to maintain cell stability, the cells go crazy and get excitable.
Acute situation in a patient with uncontrolled hyperthyroidism, usually precipitated by infection or surgery. It is life threatening because of the resulting hyperthermia, tachycardia, and heart failure and delirium
Thyrotoxicosis or thyroid storm
Elevated levels of adrenocorticoid hormone (ACTH) can cause elevated glucocorticoid levels secreted from the adrenal cortex above the kidney OR this can be caused by too much high-dose steroid medicine.
Cushing's Syndrome
Clinical manifestations of Cushing's Syndrome
Obesity (truncal), moon face, hypertension, cardiac hypertrophy, purple striae, muscle wasting, skin ulcers, hirsutism, amenorrhea
Clinical manifestations of Addison's Disease
Hyperpigmentation, low blood pressure, weakness, weight loss, N/V/D/C/abd pain, vitiligo
clinical manifestations of Adrenal Crisis
Fever, syncope, convulsions, hypoglycemia, hyponatremia, severe vomiting and diarrhea
