eg hormones

• GH (growth hormone), also called somatotropin, Promote growth of all body tissue
• TSH (thyroid-stimulating hormone)

   Stimulate thyroid gland to produce thyroid hormone
• ACTH (adrenocorticortopin hormone), Stimulates adrenal cortex to produce cortical hormones; aids in protecting body in stress situations (injury, pain)
• FSH (follicle-stimulating hormone)

   Stimulates growth and hormonal activity of ovarian follicles; stimulates growth of testes; promotes sperm cell development
• LH (luteinizing hormone)

   Causes development of corpus luteum at site of ruptured ovarian follicle in female; stimulates testosterone secretion in male
• PRL (prolactin) Stimulates milk secretion by mammary gland
• ADH (antidiuretic hormone; vasopressin) Promotes water reabsorption in kidney tubules; causes blood vessels to constrict
• oxytocin Causes uterine contraction; causes milk ejection from mammary gland
• thyroxine or tetraiodothyronine and triiodothyronine Increase metabolic rate and heat production, influencing both physical and mental activities; required for normal growth
• parathyroid hormone Regulates calcium exchange between blood and bones; increases blood calcium level
• epinephrine (adrenaline) Response to stress; increases respiration, blood pressure, and heat rate
• melatonin

  Regulates mood, sexual development, and daily cycles in response to environmental light
• cortisol (hydrocortisone) Aids in metabolism of carbohydrates, protein, and fats, active during stress
• aldosterone Aids in regulating electrolytes and water balance
• sex hormones May influence secondary sexual characteristics
• Insulin

   Aids glucose transport into cells; required for cellular metabolism of nutrient, especially glucose; decreases blood sugar levels
• glucagon Stimulates liver to release glucose, thereby increasing blood sugar levels
• testosterone development of sexual organs plus development of secondary sexual characteristics; stimulate maturation of sperm cells
• Estrogen Stimulates growth of primary sexual organs plus development of secondary sexual characteristic
• progesterone Prepare uterine lining in implantation of fertilized ovum; aids in maintaining pregnancy; stimulates development of mammary glands’ secretory tissue
