neurobio final review quiz
|Which of the following differentiates the AMPA and the NMDA glutamate-gated channels?|| The activation of NMDA receptors can cause widespread and lasting changes in the postsynaptic neuron.|
The NMDA-gated channels are permeable to both Na+ and Ca2+.
The inward current through NMDA-gated channels is voltage-dependent.
|Only EPSPs can act through spatial summation.||False.|
|The synaptic vesicles containing acetylcholine are positioned at the active zone, which is a release site on the postsynaptic terminal.||False.|
|Otto Loewi was credited for which of the following discoveries?||Showing that a soluble substance was released from the vagus nerve, altering heart rate.|
|ligands for AMPA receptor, NMDA receptor, and kaintase receptors are||agonists|
|Examples of inhibitory neurotransmitters are:||glycine and gaba.|
|Which of the following is NOT involved in vesicle exocytosis?||dynamin|
|A metabotropic neurotransmitter receptor is:|| not an ion channel |
activating second messenger systems following binding of the neurotransmitter
leading to an opening of an ion channel from the inside out
sometimes coupled to trimeric G proteins
|The following neurotransmitters are amines, except:||Glycine|
|______ causes neuromuscular paralysis by __________, whereas ___________ causes neuromuscular paralysis by _________.||DTT, inhibiting the acetylcholinesterase, curare, binding and blocking the Ach channels from opening|
