Study Notes
Endocrine System Overview
- The endocrine system is a network of glands that secrete hormones to regulate body functions
- The system works smoothly when functioning properly
- The hypothalamus, pituitary gland, and nervous system form a central network that controls other glands
Hormonal Regulation
- Hormones are chemical messengers that relay information to cells and organs to regulate body functions
- The endocrine system regulates body homeostasis
Hypothalamus
- Regulates the autonomic nervous system (ANS)
- Controls various bodily functions including temperature, thirst, blood pressure, and sleep
- Controls pituitary hormone release
Corticotropin-releasing Hormone (CRH)
- A hormone released by the hypothalamus to trigger the release of cortisol from the adrenal glands
- Part of the hypothalamus "TALE" (temperature, appetite, libido, emotion) mnemonic
Thyrotropin-releasing Hormone (TRH)
- A hormone released by the hypothalamus to trigger the release thyroid-stimulating hormone (TSH) from the pituitary gland
Growth Hormone-releasing Hormone (GHRH)
- A hormone released by the hypothalamus to trigger the release of growth hormone from the anterior pituitary gland
Somatostatin
- A hormone released by the hypothalamus that inhibits the release of growth hormone
Pituitary Gland
- Considered the "master gland"
- Located near the hypothalamus
- Regulates other glands
- Anterior pituitary releases hormones like growth hormone (GH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), prolactin, luteinizing hormone (LH), thyroid-stimulating hormone (TSH)
- Posterior pituitary releases antidiuretic hormone (ADH) and oxytocin
Thyroid Gland
- Follicular cells secrete thyroxine (T4) and triiodothyronine (T3) to regulate metabolism and protein synthesis
- C cells secrete calcitonin to manage calcium and phosphorus homeostasis
Parathyroid Glands
- Release parathyroid hormone (PTH)
- Regulates calcium and phosphate homeostasis and bone calcification in blood
Adrenal Glands
- Adrenal cortex releases corticosteroids like aldosterone to regulate potassium and sodium levels and maintain fluid balance
- Examples of corticosteroids include cortisol.
Other Glands (from the figures)
- Pineal gland produces melatonin
- Thymus produces thymosin, supporting immune system T-cell development
- Pancreas produces insulin, glucagon, and amylin, regulating blood sugar
- Ovaries produce estrogen and progesterone, regulating female reproductive system and pregnancy
- Testes produce testosterone, regulating male characteristics
- Kidneys convert vitamin D into its active form
- Adrenal medulla releases epinephrine and norepinephrine, aiding the fight-or-flight response
