Important Questions on Neuron
What is saltatory conduction of a nerve impulse?
Depolarization of a nerve fibre is caused due to influx of sodium ions.
Saltatory conduction is faster than the continuous conduction.
Saltatory conduction occurs in unmyelinated axons.
Define saltatory conduction of nerve impulses.
Most of the neurons in the body are unipolar.
The neurons that have two extensions, one axon and one dendrite are called _____ neurons.
Neurons in the retina of eye are bipolar.
Multipolar neuron has one axon and many dendrites.
Unipolar neurons are found dorsal root ganglion of the spinal nerve.
Explain the structure of a multipolar neuron. Where are they found?
Which among the following form the part of a synapse?
In the given image, label the parts (i), (ii) and (iii).
The synaptic vesicles are present near the presynaptic membrane of a synaptic junction.
In the resting state of the neural membrane, diffusion due to concentration gradients, if allowed would drive
