WebAlong the axon there are periodic gaps in the myelin sheath called nodes of Ranvier, which are sites where the signal is “re-charged” as it travels along the axon. Neurons contain organelles common to many other cells, such as a nucleus and mitochondria. They also have more specialized structures, including dendrites and axons. WebHowever, technical advances in the imaging and analysis of mitochondria in living neurons and significant insights into the mechanisms that regulate mitochondrial dynamics have allowed the field to advance. Mitochondria have now been attributed important roles in the mechanism of axon extension, regeneration, and axon branching. rayleigh station essex https://billfrenette.com
