(2) From site A to site B on outerside
(3) From site B to site A on innerside
(4) Both A and B
(1) From site A to site B on innerside
(2) From site A to site B on outerside
(3) From site B to site A on innerside
(4) Both A and B

Nerve impulse is transmitted from one neuron to another neuron by the means of
(1) Synapse
(2) Junction
(3) Both A and B
(4) Current only
Which of the following has not to be there in a synapse?
(1) Pre synaptic neuron
(2) Post synaptic neuron
(3) Synaptic cleft
(4) None of these
Which of the following is not associated with electrical synapse?
(1) No synaptic cleft
(2) Pre synaptic membranes and post synaptic membranes are in close association with each other
(3) Electric current flow directly from one neuron to other neuron through synapse
(4) Very common synapse in our system
Transmission of an impulse across electrical synapses
(1) Is very different to impulse conduction along a single axon
(2) Is very similar to impulse conduction along a single axon
(3) Is same as that of chemical synapse
(4) Both A and C
Which of the following is not associated with Impulse transmission across an electrical synapse?
(1) Faster than chemical synapse
(2) Rare in our system
(3) No synaptic cleft
(4) Impulse transmission is not similar as that of transmission within a neuron
Synaptic cleft is not
(1) Separated by pre synaptic and post synaptic neurons
(2) a fluid filled space
(3) A part of synapse
(4) Present in all synapses
Which of the following is not associated with axon terminals?
(1) Synaptic vesicles

Which of the following is not associated with chemical synapse?
(1) Slower than electrical synapse
(2) Synaptic cleft
(3) Release of neurotransmitter
(4) Transmission is similar as that of nerve impulse within a neuron
