preparation material
which of the following receptors signals through coupling to a Gq - correct answer ✔✔- alpha 1
- 5-HT2
which of the following is true regarding the 5-HT pathways - correct answer ✔✔- slow wave
sleep regulation is mediated by the 5-HT2 receptor
which of the following is true for depression - correct answer ✔✔- when treatment of
depression results in greater than 50% improvement in symptoms, the patient is called to be in
response
which of the following is true for MAO - correct answer ✔✔- MAO inhibitors was originally
discovered because of antidepressive "side effect" in patients treated for tuberculosis
- increased MAO-A activity was suggested to be linked to some types of treatment-resistant
depression
which of the following is true for tricyclic antidepressants - correct answer ✔✔- tricyclic
antidepressants cause weight gain due to blockade of H1 histamine receptor
- tricyclic antidepressants was originally discovered because of the anti depressive "side effect"
in patients treated for schizophrenia
which of the following is true for alpha 1 subtype adrenergic receptors - correct answer ✔✔-
located in the sympathetic system where it controls urinary retention
which of the following is true for NE-serotonin interaction - correct answer ✔✔- terminal
adrenergic heteroreceptors inhibit adenyl cyclase activity and cause decrease in serotonin
release
, - the NE system in the brainstem acts to accelerate serotonin release
