Ch 10 - Synaptic Integration in CNS

Question 0

a central neuron can receive blank or blank input

Answer 0

excitatory, inhibitory

Question 1

a central nerve cell receives connections from blank neurons

Answer 1

100s-1000s

Question 2

a single central neuron responds to different inputs, each mediated by a distinct transmitter called a blank

Answer 2

neurotransmitter

Question 3

binding of neurotransmitter directly opens ion channel in this receptor

Answer 3

ionotropic

Question 4

binding of transmitter indirectly regulates a channel by second messengers in this receptor

Answer 4

metabotropic

Question 5

glutamate causes blank in the brain

Answer 5

excitation

Question 6

gaba and glycine cause blank in the cns

Answer 6

inhibitory

Question 7

when ipsp’s shape the pattern of firing

Answer 7

sculpting

Question 8

type 1 synaptic terminals

Answer 8

glutamatergic

Question 9

type 2 synaptic terminals

Answer 9

gabaergic

Question 10

there is a blank density of receptors in type 1 but not in type 2

Answer 10

high

Question 11

type 1 synaptic terminal is more dendritic and synapses at blank of the neuron

Answer 11

spine

Question 12

glutamate excitatory post synaptic current

Answer 12

central synapse

Question 13

2 epsc

Answer 13

nmda, ampa

Question 14

at resting membrane potential, blank block the pore of blank channels

Answer 14

magnesium, nmda

Question 15

drug that blocks nmda receptors

Answer 15

apv

Question 16

the currents seen with apv will be only blank because blank are blocked

Answer 16

ampa, nmda

Question 17

current decay without nmda is much blank

Answer 17

slower

Question 18

reversal potential is when the current is blank

Answer 18

0

Question 19

when the trigger zone has a high density of blank channels, the threshold is blank

Answer 19

sodium, low

Question 20

a dendrite has a blank action potential

Answer 20

back propagating

Question 21

an axon has a blank action potential

Answer 21

forward propagating

Question 22

strong depolarizing blank generates ap

Answer 22

epsp
