How do nerve impulses get transmitted?
Answers
Nerve impulses transmit in the form electrical impulses from one nerve to another via a microscopic gap called Synapse.
Nerve impulse is transmitted from one neuron to another as a result of change in the polarity of the neuron. When the signal arrives at the neuron, change in the concentration of ions occur i.e. pottassium, sodium and calcium ions due to which action potential is generated and signal is transmitted. There is space between two neurons that is known as synapse. In case of chemical signalling, neurotransmitters are released at the synapse that bind to receptors on the next neuron and signal is transmitted. In case of electrical signalling, there is change in the concentration of ions at the synapse that result in generation of action potential and transmission of impulse.
