  1. The endocrine system Prepared by: SharinaHadjiManan Johara T. Udtog

  2. Hormones [Gk. Hormaoinstigate], are chemical messenger produced in one part of the body that controls the activity of other parts.

  3. Three types of HORMONES • Steroid Hormone • Derivatives of the Amino Acid Tyrosine • Proteins or Peptides

  4. Principal endocrine glandsandhormones in the body

  5. Endocrine Gland:HypothalamusHormone Released: Hypothalamic -releasin & release-inhibiting hormones Target Tissues/Organs: Anterior pituitary Function(s) of Hormones: Regulate anterior pituitary hormones

  6. Endocrine Gland:Posterior pituitaryHormone Released: Antidiuretic (ADH) Target Tissues/Organs: Kidneys Function(s) of Hormones: Stimulates water reabsorptionby kidneys

  7. Endocrine Gland:Posterior pituitaryHormone Released: Oxytocin Target Tissues/Organs: Uterus, mammary glands Function(s) of Hormones: Stimulates uterine muscle construction, release of milk by mammary glands

  8. Endocrine Gland:Anterior PituitaryHormone Released: Thyroid-stimulating (TSH) Target Tissues/Organs: Thyroid Function(s) of Hormones: Stimulates thyroid hormone Synthesis and secretion

  9. Endocrine Gland:Anterior PituitaryHormone Released: Adrenocorticotropic (ACTH) Target Tissues/Organs: Adrenal cortex Function(s) of Hormones: Stimulates adrenal cortex

  10. Endocrine Gland:Anterior PituitaryHormone Released: Gonadotropic [follicle-Gonads stimulating (FSH),luteinizing (LH) Target Tissues/Organs: Gonads Function(s) of Hormones: Egg and sperm production and sex hormone production

  11. Endocrine Gland:Anterior PituitaryHormone Released: Prolactin (PRL) Target Tissues/Organs: Mammary glands Function(s) of Hormones: Milk production

  12. Endocrine Gland:Anterior PituitaryHormone Released: Growth (GH) Target Tissues/Organs: Soft tissues bones Function(s) of Hormones: Cell division, protein synthesis and bone growth

  13. Endocrine Gland:Anterior PituitaryHormone Released: Melanocyte-stimulating (MSH) Target Tissues/Organs: Melanocytes in skin Function(s) of Hormones: Unknown function in humans regulates skin color in lower vertebrate

  14. Endocrine Gland:ThyroidHormone Released: Thyroxine (T4) and triidothyronine (T3) Target Tissues/Organs: All tissues Function(s) of Hormones: Increase metabolic rate; Regulates growth and development

  15. Endocrine Gland:ParathyroidHormone Released: Parathyroid (PTH) Target Tissues/Organs: Bones, kidneys, intestine Function(s) of Hormones: Raises blood calcium level

  16. Endocrine Gland:ThyroidHormone Released: Calcitonin Target Tissues/Organs: Bones, kidneys, intestine Function(s) of Hormones: Lower blood calcium level

  17. Endocrine Gland:Adrenal cortexHormone Released: Glucocorticoids (cortisol) Target Tissues/Organs: All tissues Function(s) of Hormones: Raises blood glucose level; stimulate breakdown of protein

  18. Endocrine Gland:Adrenal cortexHormone Released: Mineralocorticoids (cortisol) Target Tissues/Organs: All tissues Function(s) of Hormones: Reabsorb sodium and excrete potassium

  19. Endocrine Gland:Adrenal cortexHormone Released: Sex hormones Target Tissues/Organs: Gonads, skin, muscles, bones Function(s) of Hormones: Stimulate reproductive organs and bring about sex characteristics

  20. Endocrine Gland:Adrenal medullaHormone Released: Epinephrine and norepinephrine Target Tissues/Organs: Cardiac and other muscles Function(s) of Hormones: Emergency situations; raise blood glucose level

  21. Endocrine Gland:PancreasHormone Released: Insulin Target Tissues/Organs: Liver, muscles; adipose tissues Function(s) of Hormones: Lower blood glucose level; promotes formation of glycogen

  22. Endocrine Gland:PancreasHormone Released: Glucagon Target Tissues/Organs: Liver, muscles; adipose tissues Function(s) of Hormones: Raises blood glucose level

  23. Endocrine Gland:TestesHormone Released: Androgens (testosterone) Target Tissues/Organs: Gonads, skin, muscles, bones Function(s) of Hormones: Stimulate secondary male sex characteristics

  24. Endocrine Gland:OvariesHormone Released: Estrogens and progesterone Target Tissues/Organs: Gonads, skin, muscles, bones Function(s) of Hormones: Stimulate female sex characteristics

  25. Endocrine Gland:Pineal glandHormone Released: Melatonin Target Tissues/Organs: Brain Function(s) of Hormones: Circadian and circannual rhythms; possibly involved in maturation of sex organs
