Endocrine system 48
Study cards for endocrine system
What hormones are produced by the thyroid?
What hormones are produced by the parathyroid?
parathyroid hormone (PTH) aka paparathormone
What is the difference between Endocrine glands and exocrine glands?
Endocrine glands do not have ducts and the hormones are secreted directly into the blood or target cell. Exocrine glands secrete their hormones through ducts.
What are normal affects of aging effects on the endocrine system?
Decreased hormone production and secretion
Altered hormone metabolism and biologic activity
Decreased responsiveness of target tissues to hormones
Alterations in circadian rhythms.
What are the 6 prevelent clinical manifestations of hyperthyroidism/Graves Disease/Toxic Goiter?
Dyspnea r/t increased O2 consumption
Exophthalmus (Abnormal protrusion of the eyeball or eyeballs)
What are the expected diagnostic studies for hyperthyroidism/Graves disease/Toxic Goiter?
T3 & T4 levels increased
TSH levels decreased if target organ is cause
TRH suppression test
Thyroid nuclear scan
Thyroid antibody studies
Why are beta blockers given to patients with Hyperthyroidism? What is a common beta blocker given?
To prevent palpatations
What hormones are produced by the Anterior Pituitary (Adenohypophysis)? (7)
Growth hormone (GH) or Somatotropin (STH)
Thyroid-stimulating hormone (TSH) or thyrotropin
Adrenocorticotropic hormone (ACTH)
---- Follicle-stimulating hormone (FSH)
---- Luteinizing hormone (LH)
Melanocyte-stimulating hormone (MSH)
What hormones are produced by the Posterior Pituitary (Neurohypophysis)?
Antidiuretic hormone (ADH) or vasopressin
What are the main signs of Thyroid Storm?
Fever-hyperthermia to 105
What hormones are produced by the Adrenal Medulla?
What are the hormones produced by the Adrenal Cortex?
Corticosteroids (e.g., cortisol, hydrocortisone)
Androgens (e.g., testosterone, androsterone) and estrogen
Mineralocorticoids (e.g., aldosterone)
What are the hormones produced by the Pancreas (Islets of Langerhans)?
Insulin (from beta cells)
Amylin (from beta cells)
Glucagon (from alpha cells)
Cortisol levels rise early in the day and decline toward evening. This is an example of
Rhythms of secretions originate in brain structures. A common physiologic rhythm is the circadian rhythm, in which a hormone level fluctuates predictably during a 24-hour period.
Which is a main advantage of a 24-hour urine collection done for hormone levels?
Short-term fluctuations are eliminated
The major advantage of a 24-hour urine sample is that the short-term fluctuations in hormone levels seen in plasma samples are eliminated
What is Laryngeal Stridor?
harsh, vibratory sound occurs during inspiration and expiration as a result of edema of the laryngeal nerve.
What are the clinical manifestations of Hyperparathyroidism?
Hint* Moans, Groans, Stones, & Bones
Muscle weakness, fatigue
Increased need for sleep
Condition of excessive secretion of growth hormone
Condition of overproduction of ADH
Syndrome of inappropriate ADH
Condition of underproduction of ADH
Diabetes Insipidus (DI)
Conditions that involves a decrease in one or more of the pituitary hormones
Autoimmune disease of thyroid enlargement and excessive thyroid hormone secretion
Condition of sustained increase in synthesis and release of thyroid hormones
Syndrome of hypermatabolism resulting in excess t
Rare acute condition in which all hyperthyroid manifestations are heightened
Thyrotoxic crisis (Thyroid Storm)
Condition inadequate circulating parathyroid hormone
Condition of excess aldosterone secretion
