What is nerve impulse how is nerve impulse transmitted on axon and?
Answers
Reversal of electrical charge across the membrane of a resting neuron that travels down the axon of the neuron as a nerve impulse. Chemical that carries a nerve impulse from one nerve to another at a synapseThe transmission of a nerve impulse along a neuron from one end to the other occurs as a result of electrical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized—that is, there is a difference in electrical charge between the outside and inside of the membrane.
Answer:
Transmission of nerve impulse along the
axon
1. The excitable neurons iransmit ihe impulse
through changes in electrical charges across
the neuronal membrane.
2. The external tissue fuid has both Nat and K
ions.
3. This process is called sodium pump or Na-K
exchange pump.
Generation of nerve impulse : Occurs through
depolarization.
5. Saltatory conduction takes place in medullated
nerve fibres.
