- Endocrine System
- Mechanisms of hormonal regulation
- General characteristics of hormones:
- specific rates and rhythms of secretion
- Circadian or diurnal
- Pulsatile and cyclic
- Patterns that depend on levels of circulating substrates (calcium, sodium, potassium, or the hormones themselves)
- operate with feedback systems: positive or negative
- affect only cells with appropriate receptors and then act on those cells to initiate specific cell functions or activities
- steroid hormones -excreted directly by kidneys or metabolized by the liver, which inactivates them and renders the hormone more water soluble for renal excretion; peptide hormones are catabolized by circulating enzymes an eliminated in the feces or urine
- specific rates and rhythms of secretion
- Hormone release occurs in response to an alteration in the cellular environment or in the process of maintaining a regulated level of certain hormones
- hormone releases regulated by:
- chemical factors (blood glucose or calcium levels)
- endocrine factors (a hormone from one endocrine gland controlling another endocrine gland)
- neural control
- hormone classification by structure
- water soluble
- Peptides
- growth hormone
- insulin
- leptin
- parathyroid hormone
- prolactin
- Peptides
- water soluble
- General characteristics of hormones:
- Mechanisms of hormonal regulation
- glycoproteins
- follicle stimulating hormone
- luteinizing hormone
- thyroid stimulating hormone
- polypeptides
- ACTH
- ADH
- calcitonin
- endorphins
- Glucagon
- hypothalamic hormones
- lipotropins
- melanocyte stimulating hormone
- oxytocin
- somatostatin
- thymosin
- thyrotropin-releasing hormone
- animes
- Epinephrine
- norepinephrine
- lipid soluble
- thyroxine
- T4
- T3
- Steroids
- estrogens
- glucocorticoids (cortisol)
- mineralocorticoids (aldosterone)
- progestins (progesterone)
- testosterone
- derivatives of arachidonic acid (autocrine or paracrine action)
- leukotrienes
- prostacyclin
- prostaglandins
- thromboxanes
- thyroxine
