The neurons are present in the brain and they transmit the signal across the synaptic junctions in the brain by creating a membrane potential. The neurons consist of the two parts, the cyton and the axon. The cyton is the cell body containing the nucleus and the other organelles like mitochondria, endoplasmic reticulum, ribosomes, and the nucleus. The axons transmit impulses in the neurons. The axons have long projections in the form of dendrites, which transmit the signal waves across the neuronal junctions.The impulses are transmitted by the movement of the ions in the voltage gated channels present in the membrane.
