Labeling a diagram requires applying knowledge of a concept. It is an effective form of self-assessment, enabling students to check their understanding. In the following diagram, we have illustrated the important parts of the Neuron. In the following Neuron labeled diagram, we have dendrite, cell body, axon, myelin sheath, Schwann cell, a node of Ranvier, axon terminal, and nucleus. It should be noted here that a labeled diagram can be used in mathematics, science, and language arts to help the students or researchers understand the relationship among different parts of the diagram.
