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
Why are mitochondria needed at axon terminals? - Answers
Mitochondrial distribution throughout the neuron is coordinated by microtubule-based transport machinery. This includes an array of motor proteins and adaptors to move these organelles along the microtubule tracks. In the axon, anterograde transport (microtubule plus end directed, toward the axon terminal) of … See more Neurons have one of the largest and most complex architectures of all cells in the human body. The peripheral arbors of a neuron can extend for … See more Mitochondrial proteins encoded by the nuclear genome which are synthesized in the cytoplasm must be imported into the organelle. This is regulated, at least partially, by a … See more Mitochondrial fusion and fission are mediated by dynamin-related GTPases which are conserved across eukaryotes, from yeast to humans (Figure 1, panel 3).
