Guida verificata passo dopo passo1
Begin by understanding the structure of a neuron, which includes the cell body, dendrites, and axon.
The axon is a long, slender projection that conducts electrical impulses away from the neuron's cell body.
Identify the protective covering of the axon, which is crucial for the efficient transmission of nerve impulses.
Learn that the myelin sheath is the protective covering that insulates the axon, allowing for faster transmission of electrical signals.
Recognize that the myelin sheath is interrupted at intervals by nodes of Ranvier, which facilitate rapid conduction of nerve impulses.
