How information passes through neurons?​

Dear student,

Neurons in the resting state has outer membrane positively charged and inner membrane negatively charged. As the stimulus is received by neurons, sodium ion channel opens and the membrane depolarises. Sodium ion from outside moves inside of the neuron. Due to depolarisation action potential is generated. Action potential reaches the axon of neuron. Neurotransmitter are synthesised and packed in vesicles which carries the signal of action potential. Neurotransmitter filled vesicle are fused with the pre synaptic membrane of axon with the help of calcium ions released by action potential. Neurotransmitter moves through synaptic cleft and attaches to the receptor on the post synaptic neuron. Neurotransmitter depolarises post synaptic neuron and the impulse generated by action potential moves on to next neuron and so on. In this way information passes through neurons.  Reuptake of neurotransmitter occurs at the pre synaptic neuron.

The information passes through neuron in the form of impulses.the dentrites detect stimuli in form of chemical impulses and in cell body these impulses get converted into electrical impulse amd then it passes to axon and come at nerve ending and then there is a gap between the 2 neurons called snypase where there is a fluid called neurotransmitter which converts the electrical impulse into chemical impulse and this impulse is then detected by rhe next neuron

Neurons transmit information to other neurons. Information passes from the axon of the pre-synaptic neuron to the dendrites of the post-synaptic neuron. The site were a pre-synaptic terminal ends in close proximity to a receiving dendrite is called the synapse.
