Study Notes
Serotonin (5-HT)
- Released from neurons of the brainstem and gastrointestinal tract, and thrombocytes (platelets) during coagulation (hemostasis)
- Regulates body temperature, perception of pain, emotions, and sleep cycle
- Insufficient secretion may result in decreased immune system function, depression, anger control problems, obsessive-compulsive disorder, and suicidal tendencies
Histamine
- Released from neurons of the hypothalamus, cells of the stomach mucosa, mast cells, and basophils in the blood
- Regulates wakefulness, blood pressure, pain, and sexual behavior in the central nervous system
- Increases acidity in the stomach
- Involved in the inflammatory response, vasodilation, and regulation of the immune response to foreign bodies
- Assists in fighting against microorganisms introduced into the bloodstream, causing itching of the skin or irritations of the throat, nose, and lungs
