Which axon will carry the fastest nerve impulse transmission?
a) smaller-thinner
b) smaller-thicker
c) larger-thinner
d) larger-thick
Explanation it is due to less resistance to the flow of current
Synapse
Explanation Synapses refer to the points of contact between neurons where information is passed from one neuron to the next. Synapses most often form between axons and dendrites, and consist of a presynaptic neuron, synaptic cleft, and a postsynaptic neuron
Where
is the synapse present?
a) between axon terminals of two neurons
b) between dendrites of two neurons
c) between axon terminal of one neuron
and the dendrite of another neuron
d) all of these
Explanation synapse is the junction where information is transmitted
There are ……..types of synapses.
a) two
b) three
c) four
d) many
Explanation 1. Electrical synapse and 2. Chemical synapse
Which of the following synapse are specialized for rapid signal transmission?
a) electrical
b) chemical
c) physical
d) both a and b
In electrical impulses, the cells are separated by a gap, the synaptic cleft of only……..nm.
a) 20
b) 2.0
c) 0.2
d) 0.02
Explanation: The space between two neurons across which the impulse is transmitted by a neurotransmitter is known as synaptic cleft.
