Synaptic Transmission

Question 1

what is the process of synaptic transmission

Answer 1

• ICVDL

Question 2

what does ICVDL stand for

Answer 2

• impulse
• chemical
• vesicles
• diffuse
• lock and key

Question 3

process of ICVDL (I)

Answer 3

impulse travels down axon

Question 4

process of ICVDL (C)

Answer 4

signal must be transmitted chemically

Question 5

process of ICVDL (V)

Answer 5

impulse reaches pre-synaptic terminal and vesicles release neurotransmitters

Question 6

process of ICVDL (D)

Answer 6

neurotransmitters diffuse across the synapse

Question 7

ICVDL (L)

Answer 7

'’Lock and Key’’ - neurotransmitters reach post-synaptic receptor site - impulse triggered

Question 8

what is summation

Answer 8

the net charge of the neurotransmitter dictates Action Potential

Question 9

what is Action Potential

Answer 9

how likely a neuron is to fire or not (excitation/ inhibition)

Question 10

what is excitation

Answer 10

if the neurotransmitter has a positive charge - the neuron is excited and is more likely to fire

Question 11

what is inhibition

Answer 11

if the neurotransmitter has a negative charge - the neuron is inhibited and is less likely to fire
