Generation and Conduction and Transmission of Nerve Impulse
Generation and Conduction and Transmission of Nerve Impulse: Overview
This topic illustrates the generation and transmission of nerve impulses. It furthermore explains the process of polarisation and depolarisation. Electrical synapses and chemical synapses are also discussed here.
Important Questions on Generation and Conduction and Transmission of Nerve Impulse
Saltatory conduction is faster than the continuous conduction.
Saltatory conduction occurs in unmyelinated axons.
Define saltatory conduction of nerve impulses.
Potential difference across the resting membrane is negatively charged. This is due to differential distribution of the following ions:
Action potential in neurons is generated by a rapid influx of
Dopamine is a type of
During the transmission of nerve impulse through a nerve fibre, the potential on the inner side of the plasma membrane has which type of electric charge?
The neurotransmitter between a motor and a muscle cell is serotonin.
The potential difference between outside and inside of a nerve before excitation is known as action potential.
If the Na-K pump of a neuron disintegrates, then how the neuron function will be affected?
Which of the following option correctly defines the function of sodiumpotassium pump?

Saltatory conduction of nerve impulse means:
Which of the following factors are responsible for the polarised state of the membrane?
Choose the correct sequence of the following events involved in the mechanism of impulse transmission through a chemical synapse.
a - Movement of the synaptic vesicle towards the membrane and release of neurotransmitter
b - Arrival of the action potential at the axon terminal
c - Binding of neurotransmitters with their specific receptors
d - Generation of excitatory post-synaptic potential
e - Opening of the sodium ion channels and influx of sodium ions in post synaptic neuron.
When a stimulus is applied to a site on the polarised membrane, the membrane at that site becomes freely permeable to __________ ions. It causes rapid influx of __________ ions leading to ________ of membrane.
