WebNeurones are the building blocksThe basic building block of the nervous system is a nerve cell, or neurone. Neurones are shaped differently depending on where they are in the body and what role they play. All neurones have finger-like projections called dendrites and a long fibre called an axon. 20. 24. Web17 nov. 2024 · If axons of all neurons were myelinated, nerve signals would be transmitted at higher speeds in fibers that are ordinarily unmyelinated. In which type of neuron nerve impulses are conducted very faster? Nerve impulses are conducted more rapidly in myelinated fibres than in non-myelinated fibres.
