Study Notes
Endocrine System Overview
- The endocrine system comprises nine major glands and organs
- These glands produce, store, and secrete hormones
- Hormones regulate various bodily functions, including body temperature, heart rate, and blood pressure
Pineal Gland
- Often called the "mystery gland" or "third eye"
- Secretes melatonin, a hormone crucial for sleep-wake cycles, reproduction, and cancer prevention
Pituitary Gland
- Also known as the hypophysis
- Controlled by the hypothalamus
- Anterior lobe
- Produces growth hormone (GH), regulated by growth hormone releasing hormone (GHRH) and growth hormone inhibiting hormone (GHIH/somatostatin)
- Stimulated by hypothalamus
- Thyroid-stimulating hormone (TSH), which stimulates the thyroid gland and its hormone secretions, triggered by thyrotropin-releasing hormone (TRH)
- Adrenocorticotropic hormone (ACTH), which stimulates the adrenal cortex's cortisol and related hormone secretions, stimulated by corticotropin-releasing hormone (CRH)
- CRH is produced during exercise, stress, or hypoglycemia
- Posterior lobe
- Synthesizes antidiuretic hormone (ADH, or vasopressin), which increases water reabsorption by kidney tubules and decreases urine output, thus maintaining blood pressure
Thyroid Gland
- Butterfly-shaped gland
- Produces calcitonin, triiodothyronine (T3), and thyroxine (T4)
- Regulates energy and metabolism
- Requires iodine intake
- Major fluid loss can be triggered by hemorrhages; large amounts of ADH secretion will result in arteriolar vasoconstriction
- Thyroid hormones T3 and T4, stimulated by TSH, increase glucose metabolism and heat production; essential for growth, development, and reproduction
Parathyroid Gland
- Composed of four glands
- Secretes parathyroid hormone (PTH), an antagonist of calcitonin, to regulate blood calcium
- Targets bones, small intestines, and kidneys
- Maintains blood calcium levels
Adrenal Glands
-
Located superior to each kidney
-
Adrenal cortex
- Secretes steroid hormones, including mineralocorticoids (aldosterone), glucocorticoids (cortisol), and gonadocorticoids (male androgens and female estrogens)
- Essential for regulating sodium and potassium balance, as well as blood volume and pressure
-
Adrenal medulla
- Releases epinephrine and norepinephrine, also known as adrenaline and noradrenaline, the "fight or flight" hormones.
Pancreas
- Secretes somatostatin to regulate insulin and glucagon (antagonists of each other).
- Insulin, secreted by beta cells, is stimulated by hyperglycemia, enabling glucose entry into cells
- Glucagon, secreted by alpha cells, is stimulated by hypoglycemia; it facilitates liver glycogen release increasing blood glucose
Ovaries and Testes
- The female and male reproductive organs, respectively, secrete hormones governing blood circulation, mental vigor, and sex drive.
- Ovaries secrete estrogen and progesterone, essential for the female reproductive system.
- Testes produce testosterone, important for male physical development, bone density, and libido.
Additional topics
- discussed are aging effects on the endocrine system, various disorders like Pheochromocytoma and Addison's Disease, and Cushing's Syndrome
- Additional details include the effects of chronic diseases like rheumatoid arthritis, COPD, and Crohn's disease on the endocrine system
- Further topics cover Diabetes Insipidus, Syndrome of Inappropriate Antidiuretic Hormone (SIADH) along with the diagnostic testing/treatment, and various conditions affecting the pituitary gland
- Also included are dwarfism and disorders relating to the thyroid and parathyroid glands, along with their respective signs and symptoms and treatment options
- Further medical conditions such as thyroid disorders, including Hypothyroidism, and Hyperthyroidism are mentioned in the text along with their respective etiologies and presentations
- The text also details treatment for conditions like acute pain, ineffective airway clearance, risk for injury, excess fluid volume and deficient fluid volume.
- The text notes specific issues relating to various endocrine diseases as well as their potential risks like risk for injury from decreased bone density in Hyperparathyroidism
- The text also covers other important information including complications, diagnosis, symptoms, and treatment options for various conditions.
