| Question | Answer |
|---|---|
| CATECHOLAMINES | epinephrine norepi dopamine |
| SEROTONIN | EXCITATORY AND INHIBITORY RESPONSIBLE FOR DEPRESSION |
| DOPAMINE | EXCITATORY AND INHIBITORY FOUND IN THE BASAL GANGLIA AND LIMBIC SYSTEM |
| AMINO ACID DERIVATIVES | 1. GLUTAMATE AND ASPARTATE 2. G.A.B.A. 3. GLYCINE |
| GLUTAMATE AND ASPARTATE | EXCITATORY IN THE BRAIN E.G. ANGEL DUST, PCP |
| G.A.B.A. | INHIBITORY IN THE BRAIN benzodiazepines enhance GABA production |
| GLYCINE | inhibitory neurotransmitter in the SPINAL CORD by altering Cl- permeability. afferent pathways can inhibit this STRYCHNINE- competes for glycine receptors, causing great excitation |
| NEUROPEPTIDES | two or more amino acids liked together SUBSTANCE P CAPSAICIN OPIODS |
| SUBSTANCE P | found in high concentrations in the SPINAL CORD and the HYPOTHALAMUS CAPSAICIN DEPLETES STORES OF THIS |
| OPIOIDS | ENDORPHINS, ENKEPHALINS, DYNORPHINS bind to same receptors such as morphine and opium |
| NITRIC OXIDE | formed from Arginine brief response relaxes endothelial cells FOUND: cerebrum, posterior pituitary, sup/inf colliculi. ERECTION OF THE PENIS |
