Axon regeneration - ScienceDirect

WebAbstract. Whether an axon will regenerate after it is cut depends on the balance between the intrinisic ability of the axon to regrow and the permissiveness of the environment surrounding it. The permissiveness of the environment is determined by the glial cells at the site of injury, and in the CNS both oligodendrocytes and astrocytes produce ... WebNerve Tissue. Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell. The word "neuroglia" means "nerve glue." penny and sheldon doing laundry

WebThe Brain. Brain anatomy. Each neuron in your brain has one long cable that snakes away from the main part of the cell. This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons. Depending on the type of neuron, axons greatly vary in ...
