Lecture 5

Question 1

during ________________ the first step is a neurotransmitter activates a non specific channel permeable to NA and K leading to depolarization (excitatory post synaptic potential or EPSP

Answer 1

Synaptic integration

Question 2

__________ activate on K+ or Cl- channels (inhibitory post synaptic potential

Answer 2

Neuro transmismiters

Question 3

In a relay snapse, one presynaptic AP results from

Answer 3

More commonly a neuron integrates its many inputs to produce a single output

Question 4

common excitatory Neurotransmitter -____________________________

Answer 4

glutamate

Question 5

channel ligand gated ________________ to Na+ (inward) and K+ (outward)

Answer 5

non selective permeable

Question 6

Current- at resting potential, the driving force for Na+> K+, resulting

Answer 6

in a net inward current deploring the cell

Question 7

Common inhibitory Neurotransmitters

Answer 7

Y aminobutyric acid (Gaba)

Glycine (gly)

Question 8

_____________ bind to Gaba receptor and enhance Cl- flow through channels in response to Gaba

Answer 8

benzofiazepine (=valium) and barbiturates

Question 9

A recent discovery is that two gasses carbon monoxide (CO) and nitric oxide (NO) are used by neurons as _________________ even though they do not have the character of classic neurotransmitters

Answer 9

intercellular messengers
