Transcript

  • 1. LOCAL HORMONE
  • 2. LOCAL HORMONESecreted by body tissue to act locally 1) histamine 2) serotonin 3) prostaglandins 4) erythropoietin 5) gastrointestinal hormones
  • 3. HISTAMINE Hormone that chemically similar to the hormone serotonin Produce by mast cells and basophilsFUNCTIONS: Plays a role in localized immune responses and allergic reaction Increase capillary permeability and vasodilatation Stimulates secretion of gastric juice
  • 4. SEROTONIN Itis a neurotransmitter and primarily found in platelet, brain and intestinal wallFUNCTIONS: Causes intestinal secretion and contraction of smooth muscles Blood clotting
  • 5. PROSTAGLANDIN produced naturally by the body derived from fatty acids, such as arachidonic acid or linoleic acid and they act as mediatorsFUNCTIONS: Inhibit aggregation Regulating blood pressure Blood clotting Uterine contraction during labour Mediating pain and inflammation
  • 6. ERYTHROPOIETIN Synthesized in the kidneysFUNCTIONS: to promote the differentiation and development of red blood cells and to initiate the production of hemoglobin, the molecule within red cells that transports oxygen.
  • 7. GASTROINTESTINAL HORMONE1. Gastrin2. secretin3. Cholecystokinin (CCK)
  • 8. GASTRIN Polypeptidehormone secreted by the mucous lining of the stomachFUNCTION: promote gastric juice secretion
  • 9. SECRETIN it stimulates adenylate cyclase activity and converts ATP to cyclic AMP as it combine with secretin receptor reduces acid secretion from the stomach by inhibiting gastrin release from G cell and helps neutralize the pH of the digestive products entering the duodenum from the stomach
  • 10. CHOLECYSTOKININ mediates a number of physiological processes, including digestion located in the small intestine causes the increased production of hepatic bile stimulates the contraction of the gall bladder and the relaxation of the Sphincter of Oddi
